The performance of the bare thin film composite (TFC) and TFN nanofiltration membranes was investigated for the removal of the antidepressant fluoxetine hydrochloride (FLX) from aqueous solutions. The performance of the optimized TFN nanofiltration membrane was evaluated for the removal of sertraline hydrochloride, paroxetine hydrochloride, and nortriptyline hydrochloride antidepressants from water. The results showed that the MO_r membrane loaded with 0.005 MIL-101(Fe)-NH₂ MOFs achieved the highest FLX removal percentage of 84.7%, with a permeance of 5.08 L m^–2 h^–1 bar^–1. The water permeance, FLX, chemical oxygen demand (COD), and total organic carbon (TOC) removal efficiencies of the 0.005 wt % MIL-101(Fe)-NH₂ MOF-loaded MAq membrane were 9.16 L m^–2 h^–1 bar^–1, 77.2%, 98.1%, and 99.2%, respectively. The removal efficiency of the other antidepressants using the 0.005 wt % MIL-101(Fe)-NH₂ MOF-loaded MAq membrane was in the following order: sertraline hydrochloride (75.8%) > nortriptyline hydrochloride (73.1%) > paroxetine hydrochloride (71.5%). These results demonstrate that the loading of a low concentration of negatively charged MOFs into the aqueous phase of TFN membranes can significantly improve their membrane performance for the removal of FLX from pharmaceutical wastewater.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"157 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the reaction progressed, the double-end esterification content (DEC) increased and the <i>M</i>_w showed exponential growth accompanied by an increase in gel content. The effects of various reaction parameters, including the temperature, reaction time, types and amounts of diols, polymer concentration, and <i>M</i>_w of raw polymer, on the <i>M</i>_w and gel content of the product were investigated systematically. Furthermore, this method can effectively increase the <i>M</i>_w of various mixed olefin–MAH copolymers.

{"title":"Effect of Mechanical Recycling on Structural Modification and Mechanical Behavior of PET","authors":"Gabriela Gonçalves Marques, Marion Colella, Aline Couffin, Philippe Hajji, Raber Inoubli, Véronique Bounor-Legaré, René Fulchiron","doi":"10.1021/acs.iecr.4c03818","DOIUrl":"https://doi.org/10.1021/acs.iecr.4c03818","url":null,"abstract":"Climate change and the engendered environmental stress are putting pressure on the search for greener solutions. One striking example of environmental stress is plastic pollution (Geyer et al., Sci Adv. 2017, 3, e1700782). Besides reducing plastic consumption, recycling is today one of the applicable approaches (Damayanti and Wu, Polymers 2021, 13, 1475). In this context, poly(ethylene terephthalate) (PET) is in the spotlight. More than having unique properties, PET occupies the podium of recycled polymers worldwide today (Damayanti and Wu, Polymers 2021, 13, 1475; Welle, Resour. Conserv. Recycl. 2011, 55, 865–875). However, despite efforts in PET recycling and the extensive number of published papers on the subject, many challenges continue to restrain its development. One of the reasons for this is a lack of understanding of the structural modifications caused by processing. Moreover, these changes impact both the processing step and the final product properties. This study focused on the effect of the mechanical recycling process on the mechanical response of PET. By successive cycles of extrusion and injection molding, recycled PET (rPET) could be produced and characterized. The widely described chain scission was confirmed by size exclusion chromatography. The consequent loss of viscosity was observed during the processing and by rheological measurements, rendering the process more and more challenging. A modification of the crystallization kinetics was also brought to light by different techniques, such as differential scanning calorimetry and polarized light optical microscopy. Despite the different effects on the matrix, the mechanical characterization showed a stable response. Tensile properties showed a highly ductile material with more than 400% elongation for both virgin and rPET. The notch sensitivity of this material was also observed in Izod impact tests, remaining relatively low but stable. A better understanding of the relationship between structural modifications and final properties may enable fine-tuning of impact modifier structures to enhance rPET toughness and broaden its applications.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"15 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive characterization techniques revealed that although the introduction of Sn led to a decrease in zeolite crystallinity and introduced additional metal L-acids, it resulted in a more uniform distribution of aluminum species and reduced intersectional aluminum species content.

Under optimal conditions, the NO removal efficiency reached 94.0% within 30 min. In addition, PGBR exhibited excellent durability and regeneration properties. More importantly, the PGBR achieved a NO degradation efficiency of 94.3% under natural sunlight. The kinetic parameters determined using the particle swarm optimization algorithm in a simple FPR were utilized to model the complex PGBR through CFD simulations. The RMSE value between the corrected model results and the experimental data was 3.88%. The resolved velocity and concentration fields revealed an enhanced mass transfer effect in the PGBR.

The strontium hydroxyphosphate/zinc/aluminum layered double hydroxide (Sr-HAP/LDH) composite with an intercalated spherical structure was effectively synthesized using the in-situ growth method, and it possesses multiple synergistic anticorrosion advantages. The combination of zinc/aluminum layered double hydroxide (Zn/Al-LDH) and strontium hydroxyphosphate (Sr-HAP) improves the specific capacitance, enhances electron storage, and reduces electron transfer, thereby lowering the corrosion rate. The intercalated spherical structure of the Sr-HAP/LDH composite effectively blocks electrolyte penetration. Additionally, through the Zn/Al-LDH immobilization mechanism and anion exchange, the Sr-HAP/LDH composite releases PO₄^3– from the interlayer to chelate with Fe²⁺ and Fe³⁺, while trapping the corrosive Cl^– ions within the interlayer. The electrochemical tests showed that the corrosion resistance of the Sr-HAP/LDH composite with multiple corrosion protections was 340.0% higher than that of epoxy resin and 190.4% higher than that of Sr-HAP coatings. This research offers an innovative approach for designing efficient anticorrosion materials, with significant theoretical implications and promising practical applications.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"77 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143072072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, propylene polymerization was conducted using four TiCl₄/Di/MgCl₂-type Z–N catalysts containing different Di ions and a TiCl₄/MgCl₂ blank catalyst (Cat-B) under the same conditions. For each catalyst, the distribution of three groups of active centers producing PP chains with low, medium, and high isotacticity and their <i>k</i>_p values were determined based on quench-labeling the propagation chains and extraction fractionation of the polymer product. Using bidentate internal donors (phthalate, 1,3-diether, and diol ester) as Di led to a sharp increase in the total number of active centers ([<i>C</i>*]/[Ti]), while adding ethyl acetate (Cat-A) caused no change in [<i>C</i>*]/[Ti] as compared with Cat-B. The catalysts containing phthalate (Cat-P), 1,3-diether (Cat-E), and diol ester (Cat-O) had similar active center distribution (expressed as fractions of active centers forming atactic (<i>C</i>_a*), medium isotactic (<i>C</i>_m*), and isotactic (<i>C</i>_i*) polypropylene). In contrast, Cat-A and Cat-B had more <i>C</i>_a* and less <i>C</i>_m*. The influences of Di on intrinsic reactivities (<i>k</i>_p values without distortion by monomer diffusion limitation) were more evident than those on the active center distribution. Though Di exerted weak influences on the <i>k</i>_p of <i>C</i>_a*, it strongly influenced the <i>k</i>_p of <i>C</i>_m* and <i>C</i>_i*. <i>k</i>_p values of <i>C</i>_m* centers in the four catalysts containing Di (Cat-P, Cat-E, Cat-O, and Cat-A) were close to each other, but Cat-B had smaller <i>k</i>_p values of <i>C</i>_m* and large <i>k</i>_p values of <i>C</i>_i*. Judging by the <i>k</i>_p of <i>C</i>_i* and <i>C</i>_m* centers and the characteristics of Di-MgCl₂ interactions, the catalysts studied in this work can be divided into three categories: (1) Cat-P and Cat-A with medium <i>k</i>_p of <i>C</i>_i*; (2) Cat-E and Cat-O with large <i>k</i>_p of <i>C</i>_i*; and (3) Cat-B with large <i>k</i>_p of <i>C</i>_i* but very small <i>k</i>_p of <i>C</i>_m*.

Achieving carbon neutrality and sustainability in aviation requires replacing fossil-fuel-based kerosene with kerosene derived from renewable and sustainable energy sources. This Review focuses on recent advances and challenges in the development of sustainable aviation fuel (SAF) through the one-step conversion of CO₂, known as the CO2AF process, which offers the advantages of a short route and high efficiency. We provide an overview of the bifunctional catalyst system designed to achieve both high CO₂ conversion efficiency and high aromatic selectivity as well as the application of high-pressure fluidized bed reactors that enhance mass and heat transfer rates. In addition, we discuss the engineering challenges associated with the commercial application of the CO2AF process, specifically the stability and longevity of the bifunctional catalyst in high-pressure fluidized bed reactors. Multilevel engineering principles for scaling up the CO2AF process are highlighted, focusing on the interrelationships between molecular motion, catalyst system design, reactor configuration, and overall process integration. We also compare our approach with recent research efforts across the field, aiming to bridge the gap between fundamental science and industrial-scale SAF production. By providing insights into the multiscale research required for bridging these gaps, we hope to contribute to the accelerated development of SAF technologies.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"16 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The renewable power to ammonia system (RePtA) offers significant potential and prospect to replace a large number of fossil fuel ammonia technologies. However, the RePtA system driven by renewable electricity will be under frequent dynamic operation due to the fluctuation of renewable energy. In this paper, combined with specific resource conditions and device scale in a certain area, this is utilized to construct a renewable energy to hydrogen network and integrate the renewable power to ammonia system. Comparing steady-state and dynamic-state to renewable power to ammonia systems, the levelized cost of energy (LCOE) is $0.64/kWh lower than the steady-state to ammonia system, and the levelized cost of ammonia (LCOA) is $0.12/kg lower. In light of the hydrogen shortage situation, purchasing electricity from the grid to ensure that the hydrogen load of the RePtA system meets the demand for ammonia production emerges as the optimal strategy in terms of production economy and stationarity, which reduces the energy cost by nearly $1.00/kWh and increases the annual profit by 20%. Finally, compared with the actual RePtA project at Inner Mongolia, Hydrogen tank capacity is more reasonable, and LCOA is reduced by 0.4$/kg; it is observed that the optimization is effective. This paper proposed that the techno-economic optimization of the renewable power to ammonia system based on a flexible process provides a theoretical basis for the implementation of large-scale green ammonia projects.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"23 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
