Abstract
The pour point reduction of petroleum hydrocarbon stocks is obtained by the process of reducing the nitrogen concentration of the petroleum hydrocarbon stock to an acceptable level and thereafter contacting the petroleum hydrocarbon stock in the presence of hydrogen with a catalyst comprising titanium and a Group VIII noble metal on a decationized crystalline mordenite support under pour point reduction conditions of temperature, pressure and space velocity.
