Biodiesel production from rapeseed oil and low free fatty acid waste cooking oil using a cesium modified natural phosphate catalyst.

ABSTRACT: The present study focuses on the catalytic activity of cesium modified natural phosphate in biodiesel production from rapeseed oil and low free fatty acids (FFA) used in cooking oil. The catalyst was prepared by impregnation of cesium chloride (CsCl) on the natural phosphate followed by calcination up to 800 °C. The phosphate based catalyst was thermally, structurally, morphologically, and texturally characterized in order to determinate the relationship between its physicochemical properties and its catalytic activity. The chosen catalyst was demonstrated to be an active catalyst for the transesterification of rapeseed oil achieving a biodiesel yield of 99.55% under suitable reaction conditions: a methanol to oil molar ratio of 12 : 1, reaction temperature of 70 °C, catalyst amount of 4 w
