CO2 Adsorption on Mesoporous Silica Using Response Surface Methodology (RSM)

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The aim of the current study is to investigate the CO2 adsorption on the mesoporous silica. The adsorbent was characterized by XRD, TEM, SEM, and N2 adsorption desorption. The adsorption isotherms of carbon dioxide (CO2) on the silica were investigated using a static volumetric method at various temperatures.

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 ...

Ensiling and Fermentation of Rice Hulls With Ruminal Fluid for Medium‐Chain Carboxylate Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Large quantities of rice hulls are common at milling sites in Nigeria. They are a by‐product of rice processing and can contribute to environmental degradation if not properly managed. In this study, rice hulls were pretreated by ensiling at ambient temperature and then used as substrate for medium‐chain carboxylates (MCCs) production ...

Performance Investigation of Eco‐Friendly Refrigerant Mixtures as an Alternative to R134a in Vapour‐Compression Refrigeration System

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The growing impacts of climate change and energy scarcity demand environmentally sustainable refrigeration solutions. This study investigates eco‐friendly refrigerants (R152a, R290 and R600a) and their optimized ternary mixture as alternatives to R134a. Four blend compositions were analysed using experimental testing and REFPROP 10.0 modelling

Determination of selenium speciation in the muscle, kidney, and liver from different animals treated with different selenium supplements by HPLC‐ICP‐MS

open access: yesAnimal Research and One Health, EarlyView.
Dietary selenium (Se) deficiency is recognized as a global problem, and exogenous Se supplementation can effectively enrich its levels in animal bodies. Offal tissues are equally important as meat in Se enrichment. Varying properties among Se species require information beyond total Se concentration to fully evaluate health risk/benefits.
