Research ArticleOpen accessEvery word in the titleLIPASE-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

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 accessEvery word in the titleMethanol-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 accessEvery word in the titleProduction 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
Research ArticleOpen accessEvery word 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 accessEvery word in the titleExperimental Study of Diesel Engine Generator Performance and Emission Characteristics Using a Mixture of Jatropha Oil and Rubber Seed Oil Biodiesels Along a Two-Step TransesterificationFana Gebremedhin Gebremichael, Joao Fernando ChidamoioThis study investigates the performance and emission properties of engine-generator powered using various dual biodiesel mixes prepared from two inedible feedstock jatropha and rubber. Jatropha and rubber oils had high acid values, which were 13.96 and 27.91 mg KOH/g, respectively. Therefore, a two-step transesterification process was conducted to lower the acid value to 0.28 and 0.42 mg KOH/g for jatropha … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 1 Jul 2024 · 5,124 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTransesterification of Palm Oil for the Production of BiodieselKhalizani Khalid, Khalisanni KhalidProblem statement: Palm oil is known as an important source of edible oil with significant values of renewable energy. Depletion of petroleum had captured much attention on producing biodiesel from the palm oil. Approach: The most concerning methods for the production of biodiesel were discussed, namely transesterification (alkali and acid), enzymetic approach and supercritical alcohol. Results: The results showed the … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 8,389 accessesView PDFCite
