Reduction of CO2 emission by INCAM model in Malaysia biomass power plants during the year 2016
Abstract : As the world’s second-largest palm oil producer and exporter, Malaysia could capitalize on its oil palm biomass waste for power generation. The emission factors from this renewable energy source are far lower than those from fossil fuels. This … Continue reading

Thermo-kinetic assessment of glucose decomposition to 5-hydroxymethyl furfural and levulinic acid over acidic functionalized ionic liquid
Abstract: Decomposition of biomass feedstock is a promising technique for producing versatile chemicals such as 5-hydroxymethyl furfural (5-HMF) and levulinic acid (LA). Glucose, the model compound of cellulose, is one of the most important starting components for bio-based chemical synthesis. … Continue reading

Thermo-kinetic and diffusion studies of glycerol dehydration to acrolein using HSiW-γ-Al2O3 supported ZrO2 solid acid catalyst.
Abstract: The thermo-kinetic study of gas-phase glycerol dehydration reaction using a supported g-Al2O3 nanoparticle based solid catalyst (SiW20-Al/Zr10) has been investigated. The kinetic model was established based on the reaction mechanism, taking into account two parallel reactions of glycerol degradation … Continue reading

Effects of thermal treatment on carbon cryogel preparation for catalytic esterification of levulinic acid to ethyl levulinate
Abstract: Organic catalyst, especially derived from lignocellulosic biomass, is currently being developed for application in reaction engineering. Lignin, a major constituent in biomass, is highly potential as carbon- based -derived catalyst. Carbon cryogel was prepared from acidic lignin-furfural mixtures via … Continue reading

Effectiveness of Granular Activated Carbon for Removal of Sulfamethoxazole during Ozonation
Abstract: Initial experiments were performed to screen a suitable catalyst for catalytic ozonation of sulfamethoxazole (SMX). Among catalysts investigated such as CeO2, MnO2, CeO2/MnO2, and GAC. The GAC catalyst was found appropriate for further study because it adsorbed more SMX … Continue reading

Synergistic effect in plasmonic Au/Ag alloy NPs co-coated TiO2 NWs toward visible-light enhanced CO2 photoreduction to fuels
Abstract: Plasmonic Au/Ag alloy NPs supported on TiO2 nanowires (TiO2 NWs) have been designed and synthesized through a facile hydrothermal and photo-deposition method. The samples were characterized by XRD,FE-SEM, TEM, N2-adsorption-desorption, XPS, Raman, UV–vis and PL spectroscopy. Bimetallic Au/Ag NPs … Continue reading
