Abstract
Disclosed is an improved hydroconversion process for the hydroconversion of heavy hydrocarbon feedstocks containing asphaltenes, metals, and sulfur compounds which process minimizes the production of carbonaceous insoluble solids and catalyst attrition rates. The process is characterized by the use of a catalyst which has about 0.1 to about 0.3 cc/gm of its pore volume in pores having diameters greater than 1,200.ANG. and no more than 0.1 cc/gm of its pore volume in pores having diameters greater than 4,000.ANG..
