Abstract
A method for hydrotreating residual oil which comprises utilizing a hydrotreating catalyst which contains a thermally stable composition comprising a layered metal oxide containing an interspathic polymeric oxide having a d-spacing of at least about 10 angstroms at hydrotreating conditions. Said conditions include temperature ranging from about 357.degree. C. to 454.degree. C. (675.degree. F. to 850.degree. F.), a hydrogen partial pressure of at least about 2860 kPa (400 psig) and a liquid hourly space velocity ranging between about 0.1 and 10 hr.sup.-1.
