In this study, a one-step hydrothermal carbonization (HTC) process was utilized to dispose of such biomass waste and prepare high-performance adsorption adsorbents with the assistance of sulfuric acid. The experimental parameters were optimized through response surface methodology (RSM) to achieve excellent adsorption performance for methylene blue and mass yield. Based on the RSM results, an HTC product (HTC70–2) obtained under the optimal conditions of 70 wt % sulfuric acid concentration and 2 h of reaction time had shown maximum adsorption capacity (Qmax = 384.08 mg/g) and a higher mass yield (42.90 ± 3.29%). The optimized products were analyzed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET) analysis. The results showed that HTC70–2 had rough surfaces formed by nanoparticles, developed pore structures, and abundant functional groups. Moreover, the adsorption capacity of the sample decreased by only 12.8% after five adsorption–desorption cycle experiments, showing an outstanding renewable performance. FTIR, XPS, and zeta potential analysis were used to investigate the adsorption mechanisms, revealing that electrostatic attraction and surface complexation played a main role in the adsorption process.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"30 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142841195","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}

A key point in the development of polyurea elastomers is to explore the structure–property relationship. However, few studies have focused on the effect of soft segment structures because of the limitation that the flexible soft segments are usually commercialized amine-terminated polyether. Herein, a series of polybutadiene-based polyurea elastomers were prepared to systematically investigate the influence of the network structures on the ultimate properties of the polyurea materials. In particular, the amine-terminated liquid polybutadiene rubber with tunable molecular weights and liquid polystyrene–butadiene rubber were synthesized via the degradation method for flexible regulation of the soft segment structure. The results demonstrated that performance optimization could be achieved by manipulating the degree of hydrogen bonding, which was controlled by the network structure.

In this study, acidic phosphoric chitosan (aPCS) was employed as a complexing agent in the shear-induced dissociation coupling with ultrafiltration (SID-UF) technique for the sequential separation of Pr(III) and Nd(III). SID-UF uses shear stress to reduce membrane contamination and enables efficient metal ion separation while allowing complexing agent recovery without acid decomplexation, simplifying the process and lowering costs. The complexation kinetics of Pr(III) and Nd(III) with aPCS were investigated for the first time, following a pseudo-first-order model. The SID-UF technique achieved over 97% removal efficiency under optimized conditions, with a separation factor βPr/Nd of 12.01. DFT calculations showed greater electron transfer for Nd(III) (0.2218 e) compared to Pr(III) (0.2149 e), indicating stronger complexation with Nd(III). The interaction energies further confirmed this, with Nd(III) exhibiting a more favorable binding energy of −32.19 kcal mol–1 compared to −31.09 kcal mol–1 for Pr(III). These results highlight the high selectivity, efficiency, and environmental benefits of SID-UF, making it a promising alternative for industrial rare-earth separations.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832673","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 steel industry, which plays a pivotal role in current society both in economics and in terms of environmental impact, has long been stuck in a fossil-carbon-based production methodology that requires timely innovation. As an alternative, to the carbon route, hydrogen-based reduction of iron oxides has been explored over the last 60 years and lately at accelerated speed due to huge environmental impact of the present iron- and steel-making processes. The main objective of this review is to examine the extensive literature on experimental data and different modeling approaches, focusing on the use of hydrogen as a reducing agent of iron oxides under various operating conditions (e.g., temperature, composition of the reducing gas, etc.), for different structural properties (e.g., particle size, composition, etc.), and under different mechanistic and mathematical modeling assumptions. The large variation in experimental data and modeling interpretations collected over the years has led to a large scatter in the evaluation of kinetic parameters related to the reduction process. The average activation energies calculated for the individual reactive steps show significant deviations: hematite to magnetite Ea = 74.8 ± 49.0 kJ/mol, magnetite to wüstite Ea = 66.0 ± 57.2 kJ/mol and wüstite to iron Ea = 62.0 ± 43.9 kJ/mol. This scatter shows the need to further deepen the analysis in this area, starting from molecular and microscopic phenomena all the way to the scaleup into furnace scale.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"39 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832677","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}

However, they increase channel pressure gradients and create local stagnation zones, thereby exacerbating membrane fouling. These issues result in additional costs in the water treatment process. Now to fully utilize the potential of membrane filtration technology, it is necessary to reduce the problem of membrane fouling through the development of improved membrane feed spacers. Previously an Arch-Hole (Spacer-4) configuration was introduced, and herein three new configurations with higher channel porosity and shear force than the original Spacer-4 design have been assessed alongside that design. The four innovative feed spacers were studied experimentally under conditions that generate biofouling. Channel porosity and shear stress play important roles in biofouling development. Spatial distribution of shear stress was obtained via computational fluid dynamic simulations. Findings suggest that achieving uniformity of the shear force and eliminating dead zones are more crucial than high shear stress values. Such conditions were achieved with Spacer-4 type which maintained superior flux and gave for the module itself a relative specific energy consumption of 0.26 kWh/m3, significantly better than the next best value at 0.43 kWh/m3.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"47 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832675","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}

This study proposes a sustainable alternative, biomass-derived aldehyde acid–chrome (AA–Cr) tanning, to mitigate Cl– and Cr3+ pollution. Pretanning with 3 wt % AA effectively prevented acid-induced swelling of pelts in the absence of salts at a pickling pH of 1 to 4. The dialdehyde and carboxyl groups in AA facilitated the formation of a robust AA–Cr cross-linking network. Subsequent tanning with 3 wt % chrome tanning agent led to an exceptional Cr uptake rate that exceeded 98.5%, with the AA–Cr system exhibiting superior tanning performance compared to glyoxylic acid–Cr (GA–Cr). Compared to the Cr system, the AA–Cr system achieved 89.4% and 96.3% reductions in Cl– and Cr3+ loads, respectively, while exhibiting enhanced biodegradability. Life cycle assessment revealed that the AA–Cr system demonstrates remarkably lower carbon emissions, reduced resource consumption, and diminished human toxicity.

Thermostable cellulosomes, which function at elevated temperatures, increase reaction rates and reduce cooling costs by using cohesin–dockerin interactions to colocalize hyperthermostable cellulases. Due to the noncovalent nature of the cohesin–dockerin interaction, cellulosome stability has been limited to 75 °C. Our study leverages computational design and rapid screening to introduce two different intermolecular disulfide bridges between the same cohesin and dockerin, creating two disulfide cohesin–dockerin pairs. Both disulfide pairs withstood 100 °C and denaturing conditions. Furthermore, the two disulfide bridges retained their orthogonality, expanding the number of orthogonal cohesin–dockerin interactions. Finally, at the cellulase optimal temperature of 80 °C, disulfide assembly improved the activity of a bivalent cellulosome by 26% compared to that of its noncovalent counterpart. These disulfide cohesin–dockerin interactions can be used as building blocks to construct covalent protein complexes that can endure extreme temperatures.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"87 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832679","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 curing reaction between anhydride and epoxy monomer will generate hydroxyl and ester groups, which can undergo transesterification, endowing the epoxy resin with degradation performance. Large amounts of catalysts and an extra alcoholic compound are often required to break down the cross-linked networks for complete degradation, which results in the difficult separation of the degraded product. To solve this dilemma, we synthesized an autocatalytic high-performance recyclable epoxy resin with a tensile strength of 91.9 MPa, Young’s modulus of 2.85 GPa, and a Tg of 91.3 °C. The fully cured epoxy resin can be completely degraded in hot N,N-dimethylformamide due to the fast exchange reaction between the β-hydroxyl and ester bonds autocatalyzed by the formed ternary amine in the network, which may induce loop formation and result in degradation. This fast dynamic exchange reaction also endows the fabricated CFRP composites with a strong interlaminar shear strength of 58.65 MPa and excellent self-healing capacity with a healing efficiency of 99.5%. Moreover, the CFRP composites can also be completely degraded in N,N-dimethylformamide after being heated at 140 °C for 20 min. The recycled fibers can be reused to fabricate new composites with properties comparable to those of the original ones. The degraded product can be recycled into polyurethane with excellent mechanical performance, realizing full recycling of composite materials.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"12 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142832681","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}
