Abstract:
1. A method of hydrocracking heavy oil comprising the step of hydrocracking the heavy oil in a fixed bed, a moving bed, or an ebulltaing bed with a hydrocarbon catalyst under the conditions of a pressure of 8 to 20 MPa, a temperature of 380 to 450° C., a LHSV of 0.1 to 1.0 hr −1 and an H 2 /oil ratio of 350 to 1500 Nm 3 /kL-oil, the hydrocracking catalyst comprising activated carbon extrudate as a carrier, which is activated with steam and has a proportion of pores having a pore diameter in the range of 20 to 200 nm of at least 20 vol %, the ratio by volume of pores having a pore diameter in the range of 38 to 90 nm to pores having a pore diameter in the range of 20 to 200 nm is at least 40% and has a pore size distribution having a peak in the range of 20 to 200 nm, the pore volume being measure by mercury porosimetry, wherein the catalyst consists of the said activated carbon extrudate and a member selected from the group consisting of nickel, cobalt, molybdenum, nickel and molybdenum, and cobalt and molybdenum.
