Abstract
This invention is concerned with removing metal and sulfur contaminants from residual oil fractions by catalytic contact with an improved catalyst comprising the oxides or sulfides of a Group VIB metal and an iron group metal supported on an alumina that contains dispersed Delta and/or Theta phase alumina, the catalyst having at least 45% of its pore volume in pores 30 to 150A diameter, at least 10% of its pore volume in pores less than 30A diameter, and at least 15% of its pore volume in pores greater than 300A diameter. The process can be used to prepare feedstock for catalytic cracking.
