The alternative fuels that are derived from non-fossil source are very promising fuels for the future. Catalytic cracking of vegetable oil sludge is an advanced method for obtaining of bio- fuels. The huge waste in the vegetable oil manufacture could be converted to bio-fuel. Cracking of vegetable oil sludge by HY catalyst using MAT5000 instrument is a precious method for studying this catalytic cracking reaction. By catalytic cracking, the LPG gas, gasoline product, LCO and HCO products are also formed of vegetable oil sludge.
