Process for treating waxy shale oils
A process is described for treating a waxy shale oil feedstock containing organonitrogen compounds and components boiling above about 670/sup 0/F, which process comprises contacting the feedstock with a catalyst comprising a Group VIB metal component and a Group VIII metal component on a support comprising an intimate admixture of a porous refractory oxide and a crystalline zeolite having a crystal density not less than 1.6 grams per cubic centimeter, a silica-to-alumina ratio of at least 12, and a constraint index within the range of 1 to 12 at an elevated pressure and an elevated temperature less than about 800/sup 0/F and in the presence of hydrogen so as to convert less than about 25 percent of the components boiling above about 670/sup 0/F to components boiling below 670/sup 0/F and yield a product of reduced pour point and reduced organonitrogen content in comparison to the feedstock, with the reduction in organonitrogen content being over 75 percent.
