To mitigate these issues, low-dosage hydrate inhibitors, such as antiagglomerants, are used to maintain hydrate particles in a slurry form and prevent their agglomeration. Recently, functional nanoparticles have emerged as a promising alternative dispersant. These nanoparticles can assemble at the oil–water interface, creating a physical barrier that prevents the agglomeration of hydrate particles. Unlike traditional molecular additives, nanoparticles offer several advantages: they are environmentally friendly, conveniently recyclable, and potentially cost-effective. In this study, 50 nm commercial Fe₃O₄ nanoparticles were modified with silane to tune their hydrophobicity and tested as particulate hydrate slurry dispersants in the rock-flow cell, an apparatus that can evaluate flow risk under controlled shear, temperature, and pressure conditions. The performance of the nanoparticles with different hydrophobicities and dosages was directly correlated with the morphology of hydrate distribution at steady state. A hydrate slurry phase map was used to assess the performance of the nanoparticles in mitigating hydrate agglomeration. Additionally, the reusability of the nanoparticles was also tested by recycling them with a magnet and repeating the same experiment to evaluate their performance postrecycling. This study demonstrates the potential of functional Fe₃O₄ nanoparticles as effective dispersants for enhancing gas hydrate transportability in slurry form and the associated benefit with their reusability.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"13 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816395","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 practical and facile method was proposed for preparing amino-functionalized activated carbon/graphene aerogels (KAC-GA@N) with a highly porous structure and good hydrophilicity, wherein microbubble technology, a one-step freezing process (−18 °C for 6 h), two-step hydrothermal reduction (85 and 120 °C), and amino-functionalization (in ammonium citrate solution (60 mg/mL)) were employed. Our preparation strategy provided it with extraordinary chemical and mechanical stability. It can be used as an excellent adsorbent for the removal of different organic pollutants. Moreover, KAC-GA@N had a better affinity toward cationic dye (methylene blue, MB) than anionic dye (methyl orange, MO) (183.73 mg/g vs 88.31 mg/g at equilibrium), showing a good capability of selectively separating ionic dyes. Its batch adsorption process could be well described by the pseudo-second-order kinetic model and the Langmuir isotherm model. The fixed-bed dynamical adsorption–desorption cycle experiments proved the excellent practical application potential (about 88.2% MB and 39.7% MO were separately trapped for the first filtration) and good reusability of KAC-GA@N. A possible adsorption mechanism was proposed and discussed in detail. KAC-GA@N had a higher absorption capacity and rate toward various organic solvents. The KAC-GA@N aerogel efficiently addresses the recycling issue of powdery activated carbon particles and shows strong potential for practical use in the water treatment of organic pollutants.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"21 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816393","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 study, a LaNi_<i>x</i>Fe_1–<i>x</i>O₃@SBA-15 perovskite oxygen carrier with strong oxygen storage capacity and controllable lattice transport was prepared, which was used in the chemical looping reforming process of total components of wheat straw pyrolysis volatiles, and it is expected to realize the efficient production of green hydrogen. With volatile conversion, syngas selectivity, and H₂/CO as responses, orthogonal experiments were designed and carried out based on the multifactor response surface analysis method to analyze the interaction between factors. The results showed that Ni doping reduced the metal–oxygen bond’s binding energy and improved lattice oxygen’s mobility. LaNi_0.8Fe_0.2O₃@S was considered the best oxygen carrier, whose volatile conversion and syngas selectivity were 98.0 and 84.5% and the output of H₂ and syngas was 544.9 and 880.2 mL·g^–1, respectively. Multifactor response surface analysis showed that temperature was the key factor of volatile chemical looping reforming, and there was a strong interaction between the amount of oxygen carriers and space velocity. The optimum reaction conditions were 765 °C, 150 mL·min^–1·g^–1, and 0.82 g of oxygen carriers. The experimental verification showed that the volatile conversion rate was 98.0%, and the predicted value was 98.7%, and the predicted value was basically consistent with the experimental value. Ten cycles showed that LaNi_0.8Fe_0.2O₃@S had excellent reforming performance, the volatile conversion rate had good stability with a maximum fluctuation of less than 2%, the selectivity of syngas remained around 84%, and the CH₄ content remained within 2%.

In this study, we innovatively introduced rare earth Ce species into the mesoporous zeolite ZSM-5 system through in situ synthesis and then encapsulated Pt species onto the mesoporous Ce-ZSM-5, resulting in a novel Pt/Ce-ZSM-5 catalyst with a “rare earth-zeolite-precious metal” synergistic effect. The design philosophy of this catalyst is to enhance the interaction between Ce and the zeolite carrier and to improve the dispersion of Pt nanoparticles, thereby elevating the acidity, active oxygen content, and overall catalytic performance of the catalyst. Experimental results show that when the doping amount of Ce is 10 wt % and the loading amount of Pt is 0.8 wt %, the Pt/Ce-ZSM-5 catalyst exhibits excellent catalytic activity and stability in the catalytic combustion of toluene. Through systematic characterizations, we revealed the synergistic mechanism among the mesoporous structure of the carrier, Ce species, and Pt species, which not only enhanced the chemical activity on the catalyst surface but also effectively regulated the distribution of Pt species, thus improving the catalytic efficiency. This research not only provides a new theoretical framework for the design of efficient Pt-based catalysts but also deepens our understanding of the mechanism by which rare-earth-element-doped zeolites modulate the performance of precious metal catalysts.","PeriodicalId":39,"journal":{"name":"Industrial & Engineering Chemistry Research","volume":"4 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810011","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}

SnO₂ shows potential application of the CO₂RR to HCOOH, while its low current carrier density and inappropriate adsorption energy for crucial intermediates limit its performance in terms of activity and selectivity. In this study, phthalocyanine (Pc) and tetraphenyl porphyrin (TPP) were loaded onto SnO₂ nanosheets forming composite materials with different types of N (SnO₂/Pc and SnO₂/TPP), respectively. In Pc, both pyridinic N and pyrrolic N are present, while only pyrrolic N is present for TPP. XPS analysis reveals that the obvious electronic interaction happened between the pyridinic N and Sn, regulating the electronic states of Sn sites. As a result, SnO₂/Pc composites can selectively convert CO₂ to HCOOH with a Faraday efficiency up to 90.25% and partial current density up to 16.15 mA cm^–2 at −1.3 V vs RHE, higher than SnO₂/TPP and SnO₂.
