Abstract
A catalyst is provided which comprises a hydrogenation component and a support comprising agglomerates of alumina having initially not more than 0.20 cubic centimeters per gram of its pore volume in pores greater than about 400 Angstroms in diameter and a minor amount of silica. A process for the hydroconversion of hydrocarbonaceous oils utilizing the catalyst is also provided.
Claims12
A hydroconversion process which comprises contacting a hydrocarbonaceous feedstock in the presence of hydrogen at hydroconversion conditions with a catalyst comprising:
- (a) a support having initially a surface area ranging from about 350 to about 500 m.sup.2 /g, a total pore volume of about 1.0 to about 2.5 cc/g, not more than about 0.2 cc/g of said pore volume being in pores having a diameter of more than about 400 Angstroms, said support comprising agglomerates of alumina and silica, said silica comprising less than about 10 weight percent of said support, and
- (b) a hydrogenation component selected from the group consisting of metal, metal oxide, metal sulfide of a Group VIB metal and elemental metal, metal oxide and metal sulfide of a Group VIII metal and mixtures thereof of the Periodic Table of elements.
