Biofuel can be produced from the cracking of waste cooking oil. Waste cooking oil can be converted into biofuels through a catalytic cracking process using a catalyst Ni.Mo / Zeolite. Metal concentration was varied at 0%; 0,5%; 1%; and 1,5%; with a variation of the reaction temperature, 380oC, 400oC and 420oC. Cracking process using nitrogen gas with a flow rate of 150 ml / min. Maximum product yield obtained at a temperature of 400oC with metal concentrations 1.5%, amounting to 108 ml with 43.06% biofuel conversion.
