ABSTRACT:
A hydrotreating process, particularly a hydroconversion process, wherein a hydrogenation catalyst is contacted with a hydrocarbon or hydrocarbonaceous feed containing 1050.degree. F.+ materials at a preselected high initial temperature and maintained essentially at this temperature throughout an operating run. In accordance with such mode of operation certain advantages are obtained, these including: (1) greater overall conversion of 1050.degree. F.+ to 1050.degree. F.- hydrocarbon products at a given level of hydrodesulfurization, catalyst consumption rate, with the same reactor volume and pressure requirements; (2) greater overall reduction of Con carbon; and (3) improved overall feed metals reduction.
