The variations in the proposed configurations lie in the technologies used for off-gas treatment (such as pressure swing adsorption, oxyfuel combustion, autothermal reforming, and chemical absorption) and the intensification of separation (including the incorporation of the hydration reaction of ethylene oxide) within the process. Energy efficiency analysis, techno-economic analysis (in minimum required selling price, MRSP), and life cycle assessment (on global warming potential, GWP) were conducted to evaluate all proposed schemes. Overall, this study suggests that enhancing the selectivity towards propanol and implementing a suitable off-gas treatment strategy are crucial for this process. Based on the findings, we recommend Scheme 4, which involves auto-thermal reforming for off-gas treatment, as the optimal configuration. It leads to an energy efficiency of 45.33 %. Despite the higher MRSP (3.12 USD/kg when using grey H, 7.45 USD/kg when using green H, commercial process: 1.4 to 1.6 USD/kg), it significantly reduces GWP (3.19 kg-CO-eq/kg when using grey H, 1.59 kg-CO-eq/kg when using green H) created from the conventional process (6.77 kg-CO-eq/kg). Given appropriate economic incentives, the proposed process could serve as a more environmentally friendly option for propanol production.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"266 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211245","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}

Therefore, in this study, porous carbon materials were prepared using sawdust through hydrothermal carbonization (HTC) to produce hydrochar, followed by KOH activation. The results showed that KOH-activated hydrochar had a specific surface area of 646–1195 m/g, and a micropore area of 547–1059 m/g, indicating a microporous structure was developed. The highest CO adsorption capacity at tested adsorption temperatures was achieved from activated hydrochar obtained at 750 °C (40 °C: 0.95 mmol/g; 75 °C: 0.80 mmol/g), which is higher than pristine hydrochar (40 °C: 0.05 mmol/g; 75 °C: 0.04 mmol/g). Physisorption through pore diffusion and surface coverage and chemisorption involving formation of covalent bonds between adsorbent’s surface functionality and CO both contributed to CO adsorption. Importantly, the presence of N-containing chemicals, particularly the presence of N-containing functional groups on the surface, played an important role in CO adsorption capacity. Based on the current results and relevant literature, the development of ultra-micropore and the introduction of more N-containing functional groups to the surface would be the research focuses to further increase the CO adsorption capacity.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"17 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211255","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}

To investigate the effect of the aromatization degree of MP on the properties of carbon fibers, this study prepared MP with varying aromatization degrees using the self-pressurization/N-blowing two-stage thermal condensation method with refined coal tar pitch as raw material. Mesophase pitch-based carbon fibers (MPCFs) were obtained through melt spinning, pre-oxidation, and carbonization processes. Results show that the C/H atomic ratio rises from 2.067 to 2.318 as the aromatization degree of MP increases. After carbonization at 1300 ℃, the microcrystalline structure of MPCFs becomes ordered, with obvious axial radiation in the cross-section. The carbon layers in MPCFs are tightly stacked in parallel, significantly improving tensile strength and modulus. When the C/H atomic ratio of MP exceeds 2.262, the resulting MPCFs exhibit a maximum tensile strength of 1389 MPa and a maximum tensile modulus of 167 GPa. However, when the C/H atomic ratio of MP exceeds 2.318, the excessive aromatization degree makes the MPCFs structure prone to cracking due to circumferential volume shrinkage, and the appearance of cracks reduces the tensile strength of MPCFs.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"11 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211250","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}

Converting CO into valuable products offers an attractive strategy to mitigate its environmental impact. Here, we present a highly efficient, solvent-free method for CO₂ fixation into cyclic carbonates using a novel green catalyst, β-cyclodextrin, linked to an imidazolium-based ionic liquid (β-CD-ImBr). This catalyst facilitates the conversion of various terminal and internal epoxides into cyclic carbonates with exceptional performance. Notably, β-CD-ImBr achieves up to 98 % conversion of styrene oxide to its corresponding carbonate within 24 h at 120 °C, demonstrating significant activity without needing a co-catalyst. Operating under solvent-free conditions, this method avoids environmentally harmful synthetic pathways by utilizing the hydroxyl groups of cyclodextrins as hydrogen bond donors and employing the bromine counterion to facilitate epoxide ring opening. Mechanistic studies reveal that β-CD-ImBr enhances catalytic performance by lowering the activation energy of the rate-limiting step through its hydrogen bond acceptor properties. Importantly, the catalyst is both recyclable and reusable, highlighting its cost-effectiveness and environmental benefits. This approach represents a significant advancement in sustainable chemistry, offering a green alternative for CO₂ fixation.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"26 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142211249","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}

Two cases were performed to optimize the ethane and ethylene separation process. In the first scenario, ethylene recovery was optimized under a purity constraint, resulting in an enhancement from 65.28 % to 87.19 %. In the second scenario, both ethylene recovery and energy consumption were simultaneously optimized with the purity constraint, leading to the generation of a Pareto front. From this Pareto front, two operating conditions were determined: one using TOPSIS and the other aimed at reducing energy consumption from a conventional distillation column to 0.733 MJ/kg-ethylene. Compared to conventional distillation, the vacuum pressure swing adsorption (VPSA) process showed 82.8 % recovery with 0.747 MJ/kg-ethylene and 72.21 % recovery with 0.683 MJ/kg-ethylene.

Among them, the solid phase is simulated by the Multiphase Particle-In-Cell (MP-PIC) method, and the gas phase turbulence is accurately captured by the large eddy simulation (LES) method. The flow field characteristics distribution and the reaction kinetic of NO under different parameters (coal, raw meal, tertiary air) in the gasifier were investigated, and the operating condition values for guiding industrial applications are obtained. The simulation results show that the gasifier can completely remove NO from the rotary kiln at 2.8 kg/s for coal, 30 kg/s for raw meal and 2.5 kg/s for tertiary air. The application results show that under 1.6 kg/t.cl of ammonia water combined with SNCR, NO emission and ammonia slip can be controlled below 50 mg/Nm and 5 mg/Nm, respectively.
