Development and evaluation of biodiesel fuel and by-products from jatropha oil

Abstract

ABSTRACT:Biodiesel is an environmentally friend renewable diesel fuel alternative. Jatropha seeds can be a feedstock to produce a valuable amount of oil to be converted to biodiesel using transesterification reaction. Jatropha plant has been successfully grown in southern Egypt using primary treated municipal wastewater for its irrigation. A bench scale production of biodiesel from Jatropha oil (using methyl alcohol and sodium hydroxide as catalyst) was developed with methyl esters yield of 98 %. Biodiesel was produced on a pilot scale based on the bench scale experiment results with almost the same methyl esters yield of 98 %. The produced biodiesel was evaluated as a fuel and compared with petroleum diesel according to its physical and chemical parameters such as viscosity, flash point, pour point, cloud point, carbon residue, acid value and calorific value. The experimental techniques and product evaluation results show that such properties of the produced biodiesel are near to that of petroleum diesel. A mass balance representing the transesterification process is presented in this study. Glycerol of 85 % purity was produced and evaluated as a valuable byproduct of the process. Free fatty acids and sodium phosphate salts which have industrial interesting are also produced and evaluated.

Pre-Treatment of Waste Frying Oils for Biodiesel Production

“…Therefore, WFO can be used effectively for the biodiesel synthesis, and it is found to be an economically feasible method (Supple et al, 2002). Biodiesel from WFO can reduce the cost of biodiesel production since the feedstock costs constitutes approximately 70-95% of the overall cost of biodiesel production (Diwani et al, 2009;Lam et al, 2010;Asri et al, 2014;Alves et al, 2013). The property of biodiesel depends on the type of fresh cooking oil used.…”

Examining the physicochemical properties and engine performance of biodiesel from whole seed and extracted kernels of egusi (Citrullus lanatus)

“…Two separate layers containing glycerol (bottom layer) and biodiesel (top layer) were observed. The glycerol was removed leaving only the biodiesel in the funnel 17 . The biodiesel was then washed with warm distilled water to remove soap and excess glycerol.…”

Biodiesel Production from Waste Cooking Oil Using Co-solvent Technique

“…The method we use to produce biodiesel is co-solvent method. The relevance of using a co -solvent for the production of biodiesel is studied and its effect in the reaction time, reaction temperature and yield of biodiesel [2]. The produced biodiesel from waste cooking oil are checked with the ASTM Standards to clarify the quality of biodiesel obtained in the experiment.…”
