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

open access: yesAsia-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

open access: yesAsia-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

open access: yesAsia-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.

Humidity‐Corrected Thermodynamic Modeling of Ammonium Chloride Crystallization Temperature Mechanisms and Application

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT As refineries process increasingly inferior crude oils, ammonium salt corrosion has intensified. Accurate prediction of ammonium salt crystallization temperatures and their influencing factors is therefore crucial for safe and stable operations.

Energy‐Efficient and Sustainable Design Optimization for Ternary Mixture Separation: A Comparative Analysis of Sequential Iterative Optimization and Non‐Dominated Sorting Genetic Algorithm II

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents a comparative analysis of two optimization approaches: Sequential Iterative Optimization (SIO) and Non‐dominated Sorting Genetic Algorithm II (NSGA‐II) applied to the separation of ternary mixtures (1‐butanol, isobutanol, and 2‐butanol) using Dual‐Column Distillation (DCD) and Dividing‐Wall Column (DWC) processes.
