SSZ‐13 Zeolite with Isolated Co2+ Sites as an Efficient and Durable Catalyst System for Non‐Oxidative Ethane Dehydrogenation

Angewandte Chemie International Edition, EarlyView.
Catalysts with the isolated Co2+ species in the 6MR (Co2+─Z2) and 8MR ([Co(OH)]+─Z) windows of the SSZ‐13 zeolite were synthesized for non‐oxidative ethane dehydrogenation to ethene. The Co2+─Z2 species demonstrate an unexpectedly high rate of ethene formation in comparison with the ([Co(OH)]+─Z species.

Ultrafast Biodiesel Synthesis via K2CO3‐Supported Mg‐Al Hydrotalcite Catalyst With Tailored Basicity and Mesoporous Structure

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT With the increasing global energy demand and the growing prominence of environmental issues, biodiesel has garnered significant attention as a renewable, low‐emission green energy source. Conventional hydrotalcite‐based catalysts often suffer from insufficient basicity and limited accessibility of active sites, leading to relatively long ...

Homologous Bio‐Tar and Bio‐Tar Pitch as Co‐Carbonization Agents in the Preparation of Mesophase Pitch

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The present work systematically compares the performance differences between two novel homologous materials employed as co‐carbonization agents in the synthesis of mesophase pitch. Low‐cost FCC slurry was used as the raw material, with bio‐tar (BT) and bio‐tar pitch (BTP) as co‐carbonization agents.

Mechanistic Insights Into Cellulose Dissolution in Solvents for Advanced Industrial Applications: A Systematic and Bibliometric Review

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Cellulose dissolution is important for various industries, including textiles, bioplastics, foods and pharmaceuticals, yet achieving efficient dissolution remains challenging. Deep eutectic solvents (DES) have emerged as promising alternatives to traditional solvents due to their low toxicity, biodegradability and sustainability.
