Abstract
This invention is concerned with removing metal and sulfur contaminants from residual oil fractions by catalytic contact in a novel dual bed system. In this process the oil is first contacted with a catalyst comprising a Group VIB metal and an iron group metal oxide, such as a mixture of cobalt and molybdenum oxides, composited with an alumina support that contains delta or theta phase alumina, the catalyst having at least 60% of its pore volume in pores of 100A to 200A diameter, at least about 5% of its pore volume in pores having a diameter greater than 500A, and a surface area up to about 110m.sup.2 /g. The oil is then contacted with a second catalyst of the high surface-area, cobalt-molybdenum on alumina type. The second catalyst has a major fraction of its pores in the 30 to 100A diameter range.
