ABSTRACT:
A process for catalytic hydrodewaxing of a wax-containing feed wherein the feed is subjected to hydrodewaxing conditions in a first reaction zone containing a wax-cracking catalyst, the effluent from the first reaction zone is charged to a second reaction zone containing a hydrotreating catalyst that produces an exothermic reaction and the effluent from the second reaction zone is charged to a third reaction zone containing a wax-cracking catalyst, the exothermic reaction in the second reaction zone effecting heating of the effluent, which is charged to the third reaction zone.
