Research ArticleOpen accessPhrase in the titleThe Biodiesel Production from Roast Thai Sausage Oil by Transesterification ReactionWasan Theansuwan, Kitrichai TriratanasirichaiProblem statement: This research is to study the feasibility of biodiesel production from roast Thai sausage oil by transesterification process. Approach: The objective of this study was to investigate the effects of potassium Hydroxide (K2OH3) as heterogeneous catalyst (3-9% (wt) of the feedstock) and methanol-oil molar ratio (3:1-12:1) on the yield and properties (flash point and fire point) of the … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,157 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleImmobilization of Lipase from Candida rugosa on Chitosan Beads for Transesterification ReactionM. Nasratun, H. A. Said, A. Noraziah, A.N. Abd AllaProblem statement: Further study is recommended to improve the immobilization technique and the immobilized lipase’s performance as catalysis in transesterification reaction. Approach: To investigate the ability of immobilized lipase on chitosan beads to catalyze the transesterification of cooking oil to an ester. The porous bead of chitosan was used for immobilization of lipase from Candida rugosa by physical adsorption. Parameters … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnzymatic Kinetics of Fatty Acids Methyl Ester from Kapok Seed Oil (Ceiba Petandra) Using Lipozyme TL IMErin Ryantin Gunawan, Dedy Suhendra, Baiq Rizkia Miftahatul HasanahSynthesis of Fatty Acids Methyl Ester (FAME) utilizing oil extracted from kapok seeds (Ceiba petandra) and catalyzed by lipozyme TL. 1M via enzymatic kinetics transesterification was succesfully conducted A mixture of different FAME, widely known as biodiesel is one of the sources of renewable energy. A kinetic analysis was investigated to identify the reaction model and the rate equation and … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 2 Jan 2018 · 9,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnzymatic Synthesis of Palm Alkyl Ester Using Dialkyl Carbonate as an Alkyl DonorsRoila Awang, Choo Yuen MayProblem statement: Though efficient in terms of reaction yield and time, the chemical approach to synthesizing alkyl ester has drawback such as difficulties in the recovery of glycerol and the need for removal of salt residue. On the other hand, biocatalyst allow for synthesis of specific alkyl esters and easy recovery of glycerol. However, the solvent-free alcoholysis, does not give … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethanol-Based Transesterification Optimization of Waste Used Cooking Oil over Potassium Hydroxide CatalystCholada Komintarachat, Sathaporn ChuepengProblem statement: Waste used Cooking Oil (WCO) harmfully affected to environment and human’s health can be a feedstock for producing biodiesel. Approach: The conversion of Fatty Acid and Free Fatty Acid (FFA) of WCO with 15.0% w/w FFA content to biodiesel was studied through transesterification reactions. This work investigated the effects of alcohol and catalyst quantity, reaction time and temperature … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 9,739 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,467 accessesView PDFCite
