Enzymatic Alholysis For Biodiesel Production From Waste Cooking Oil
Huge efforts have been carried out in recent years in order to develop an alternative fuel from renewable resources, such as biodiesel fuel. Therefore, the use of cooking oil as raw material is a very interesting alternative for the production of biodiesel. In this work, waste frying oil was used as raw material for enzymatic biodiesel production. Moreover, this study analyzes the influence of ...
متن کاملA Two-step Catalytic Production of Biodiesel from Waste Cooking Oil
Waste cooking oil (WCO) was used as a potential feedstock for biodiesel production. High levels of free fatty acids (9.85% w/w) in WCO made it an undesirable substrate for direct transesterification reaction. To solve this issue, a two-step process was implemented in this research. Firstly, esterification reaction was performed in presence of sulfuric acid as a common acid catalyst to reduce th...
متن کاملWaste Cooking Oil as an Alternate Feedstock for Biodiesel Production
As crude oil price reach a new high, the need for developing alternate fuels has become acute. Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work, biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax, Nova Scotia, Canada. Ethyl alcohol with sodium hydroxide as a catalyst was use...
متن کاملOptimized Production of Biodiesel from Waste Cooking Oil by Lipase Immobilized on Magnetic Nanoparticles
Biodiesel, a non-toxic and biodegradable fuel, has recently become a major source of renewable alternative fuels. Utilization of lipase as a biocatalyst to produce biodiesel has advantages over common alkaline catalysts such as mild reaction conditions, easy product separation, and use of waste cooking oil as raw material. In this study, Pseudomonas cepacia lipase immobilized onto magnetic nano...
متن کاملBiodiesel Production from Used Cooking Oil
Production of biodiesel was involved transesterification process that implicated the reaction between used cooking oil and methanol with aid of KOH. The reaction was carried out at 15 min, 30 min, 60 min, 90 min, and 120 min to evaluate the effect of reaction time on the yield of fatty acid methyl ester (FAME). The highest yield of FAME was obtained at reaction time 60 min. Besides that, the yi...
