ABSTRACT:
An improved processing technique is provided for gas oil pour point reduction and dewaxing. The improved technique comprises contacting an appropriate gas oil feedstock with a catalyst comprising a crystalline aluminosilicate zeolite characterized by a silica/alumina mole ratio of at least 12 and a constraint index, hereinafter defined, within the approximate range of 1 to 12 in the presence of a relatively large amount of co-fed water. The amount of co-fed water is maintained at from about 0.5 to about 15 moles of water/mole of gas oil feedstock.
