Abstract: Energy crisis and threats of global warming has accelerated the thrust for new renewable energy resources. Recycling greenhouse gases seems eminently potential to produce sustainable fuels as well as to reduce carbon emission. Various possibilities for implementing low carbon … Continue reading →

Abstract: The synthesis of fatty acid ethyl esters (FAEEs) by a two-step in situ (reactive) esterification/transesterification from Jatropha curcas L. (JCL) seeds using microwave system has been investigated. Free fatty acid was reduced from 14% to less than 1% in … Continue reading →

Abstract: Glycerol, an alcohol and oxygenated chemical from biodiesel production, has enormous potential to be converted into higher value-added fuels and chemicals. Conversion of glycerol to olefins, although relatively new, has been proven viable by the limited number of literatures … Continue reading →

Abstract: In this work, a set of hybrid catalysts were synthesized, characterized and tested for the conversion of glucose to levulinic acid. The hybrid catalysts with 1:1, 1:2 and 2:1 weight ratios of CrCl3 and HY zeolite were prepared via the … Continue reading →

Abstract: 5-Hydroxymethylfulfural (5-HMF) is a versatile compound obtained from renewable resources such as agricultural residue and biodegradable waste. 5-HMF has potentials to replace fuel-based petroleum and fine chemicals. Glucose, a monosaccharide is often used as a model compound to produce … Continue reading →

Abstract: Fossil fuel depletion, environmental concerns, and steep hikes in the price of fossil fuels are driving scientists to search for alternative fuels. The characteristics of biodiesel have made the pursuit of high quality biodiesel production attractive. Utilization of waste … Continue reading →

Abstract: Transesterification of waste cooking oil with heterogeneous (heteropoly acid) catalyst and methanol has been investigated. Response Surface Methodology (RSM) and Artificial Neural Network (ANN) were employed to study the relationship between process variables and free fatty acid conversion and … Continue reading →

Abstract: The production of lignin from empty fruit bunch (EFB) has been carried out using liquefaction method with 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) ionic liquid (IL), in presence of sulfuric acid (H2SO4) as a catalyst. Response surface methodology (RSM) based on a … Continue reading →
