Abstract
Waxy shale oil feeds containing organonitrogen and/or organosulfur components are contacted with a catalyst comprising a Group VIB metal component on a support containing a crystalline aluminosilicate zeolite of the ZSM-5 type and a porous refractory oxide under conditions of elevated temperature and pressure and in the presence of hydrogen so as to simultaneously reduce its pour point and its organosulfur and/or organonitrogen content.
