The Production of Biodiesel and Ethanol from Pressed Coconut

Abstract

Cold-pressed-coconut oil was subjected to biodiesel production. Interestingly, their partial chemical and physical properties of biodiesel (this study) were similar to commercial biodiesel. Pressed-coconut contained cellulose, hemicelluloses and lignin at 16, 34 and 8%, respectively. High cellulose was achieved after pretreatment. The highest cellulose (82%) obtained from sample pretreated with autoclave. Each sample was utilized for ethanol production by Separation saccharification and fermentation using Saccharomyces cerevisiae. The sample pretreated by sonication method yield highest ethanol (2.06%) after 84 h of cultivation.
