The research of jatropha cator oil hydrocracking by using Co/Mo Montmorillonite pillared Ti02 catalayst has been done. The hydrocracking process was conducted at 500 °C of temperature, 2 g of catalyst weight and 0.5; 1.5; 2.5; 3.5 mL/sec of hydrogen gas flow rate variation. The product of hydrocracking was calculated in percentage of non polar, polar, coke, and gas one. The density of the non …
