Petrochemicals like light olefins and BTX are essential feedstocks for the petrochemical industry. This study extends the scope of FCC technology by exploring the direct catalytic cracking of Arabian Extra Light (AXL) crude oil, using spray dried FCC-ZSM-5 modified with La and Ce oxides, in non-steam and steam conditions. The performance of the catalysts was evaluated based on the yield and selectivity of light olefins and BTX. The yield of light olefins for thermal cracking, catalytic cracking and steam catalytic cracking at 675 °C was 36.0 wt%, 43.3 wt% and 51.5 wt%, respectively. The study demonstrated that steam catalytic cracking using FCC-ZSM-5 (impregnated with 1 %La and 1 %Ce oxides) offered significant advantage over non-steam catalytic cracking. The presence of steam enhanced the conversion and shifts product distribution towards light olefins. Steam also modified the cracking mechanism by minimizing secondary reactions, reducing coke formation, and enhancing selectivity toward olefins. The findings in this study contribute to the development of efficient catalyst and process for the direct conversion of crude oil into high-value petrochemicals.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"23 ","pages":"Article 100794"},"PeriodicalIF":5.5,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144365420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we propose a direct regeneration process in two steps based on a hydrothermal relithiation and post-annealing at moderate temperature. Two NMC-materials went through chemical delithiation and subsequent relithiation: NMC from scrap, which is recovered with the conductive carbon from its original formulation and reference NMC for comparison. The results demonstrate that relithiation was effective during the first solution step, leading to a partially active material. The post-annealing treatment enhances electrochemical performances and the best ones are obtained for the samples annealed at 400 °C. Therefore, the results confirm that the presence of residual carbon does not impact relithiation or compromise its efficiency. The latter conserves its conductive properties after the relithiation process. However, an amount of the carbon has been lost during the second step; then this loss was compensated with an addition of fresh carbon, providing satisfactory electrochemical performances.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"23 ","pages":"Article 100795"},"PeriodicalIF":5.5,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144330839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the influence of channel geometry, flow dynamics, and polymer concentration on the size and polydispersity of poly(butylene oxide) (PBO) nanoparticles. PBO is a hydrophobic polymer with a low glass transition temperature (<em>T_g</em> = –71 °C) that typically forms large nanoparticles (&gt;176 nm) via bulk nanoprecipitation, as well as aggregates ranging from 3000 to 5000 nm. Using a hydrodynamic flow-focusing Ψ-geometry, we demonstrate that higher total flow rates increase convective mixing, reduce mixing times, and produce smaller, more monodisperse PBO nanoparticles. A comparative analysis of Ψ- and T-channel geometries across various dimensions revealed that Ψ-geometries consistently outperformed T-geometries due to their superior mixing efficiency. Decreasing the channel dimensions to 20 µm further improved mixing by shortening diffusion lengths and accelerating solvent–antisolvent interdiffusion. Using the Ψ-geometry, nanoparticles as small as 66 nm were achieved, whereas T-geometries produced significantly larger particles (&gt;500 nm). A linear trend between particle size and total flow was observed, best described by a power-law relationship, linking flow rate—and by extension, Reynolds number—to mixing speed and nanoparticle size. These findings highlight the pivotal role of microfluidic design and flow control in tailoring nanoprecipitation for low-<em>T_g</em>, hydrophobic polymers such as PBO.

However, LA fermentation requires the neutralization of LA to prevent the inactivation of LA-producing microorganisms, resulting in a significant amount of waste (gypsum, approximately 75 wt % per weight of LA produced) and high energy consumption during the purification of LA. Herein, we developed an LA fermentation method without neutralization using activated carbon (AC) and engineered yeast. This method exhibited high LA productivity comparable to that of conventional fermentation methods and generated zero waste from desalination. The high LA productivity was due to LA adsorption on AC, leading to an LA production concentration of 101.2 g L⁻¹ and glucose-to-LA conversion yield of 88.0 %. The LA adsorbed on AC was easily extracted by immersion in bioethanol near room temperature (30 °C). Therefore, the LA extraction has low energy consumption, and the LA-containing bioethanol can be directly used to produce ethyl lactate. In addition, because AC can be reused repeatedly for LA adsorption and extraction, an LA recovery rate of up to 99.9 % can be achieved. Consequently, the total electricity consumption of LA production can be reduced by up to 34.8 % compared with that of conventional methods. Our proposed fermentation method is not only waste reducing and energy saving but also highly productive, making it promising for the eco-friendly production of organic acids and biomass materials.</div></div>","PeriodicalId":9749,"journal":{"name":"Chemical Engineering Journal Advances","volume":"23 ","pages":"Article 100790"},"PeriodicalIF":5.5,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313450","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MOF crystals rich in small micropores may not be sufficient for effective heterogeneous catalysis, especially when the reactants are too large to access the micropores.
