摘要：
A process for producing lube oil basestocks wherein a wax containing lube oil boiling range feedstream is converted into a basestock suitable for use in motor oil applications by contacting it with a hydrodewaxing catalyst containing a medium pore molecular sieve having deposited thereon an active metal oxide and at least one hydrogenation metal selected from the Group VIII and Group VIB metals.
