Abstract In the biodiesel industry, homogeneous alkaline catalysts such as NaOH, KOH and NaOCH3 are used most widely. These catalysts provide high transesterification reaction yield and ester content with a minimal reaction time. However, homogeneous basic catalysts can not be regenerated for repeated use. Usually after the synthesis process homogeneous alkaline catalysts that are in a high concentration in the crude biodiesel and glycerol, are neutralized by using mineral acids and isolated in the form of salts. These operations and following washing and drying of crude biodiesel significantly increase the cost of biodiesel production. Therefore the use of effective heterogeneous catalysts for the transesterification reaction in biodiesel production would enable the development of a non-waste technology and would give an economic benefit. This abstract summarizes the results of investigation the influence of various synthesised heterogeneous catalysts on the rapeseed oil methanolysis process.
