<p>In a catalytic dewaxing process, a catalyst comprising from 40 to 80 wt% of ZSM-48 having a silica to alumina molar ratio of less than 200:1 and from 0.3 to 1.5 wt% of a metal or metal compound from Groups 8 to 10 of the Periodic Table of the Elements is provided in a reaction zone. The catalyst is periodically contacted in the reaction zone under dewaxing conditions with a first hydrocarbon feedstock having a wax content of less than 50 wt% and with a second hydrocarbon feedstock having a wax content of 50 wt% or more.</p>
