    摘要： The present invention relates to an ebullated bed hydrotreating process, wherein a heavy crude oil and hydrogen are introduced into an ebullated bed hydrotreating reactor from the bottom of the reactor for carrying out reaction under the heavy crude oil hydrotreating conditions, and then the reaction products are discharged from the top of the reactor; wherein a mixed catalyst is used in the ebullated bed hydrotreating reactor, said mixed catalyst is a physical mixture of at least two catalysts, A and B at a volume ratio of Catalyst A to Catalyst B being 1: (0.1-10); wherein Catalyst A has a specific surface area of 80-200m 2 /g and an average pore diameter of more than 20 nm, the pore volume of the pores having a pore diameter of 30-300nm comprises 35 vol.%-60 vol.% of the total pore volume of Catalyst A; Catalyst A contains 1.0 wt%-10.0 wt% of a metal oxide of group VIB, and 0.1 wt%-8.0 wt% of a metal oxide of group VIII, by the total weight of Catalyst A; and wherein Catalyst B has a specific surface area of 180-300m 2 /g and an average pore diameter of 9-15nm, the pore volume of the pores having a pore diameter of 5-20 nm comprises at least 70 vol. % of the total pore volume of Catalyst B; Catalyst B contains 3.0 wt%-20.0 wt% of a metal oxide of group VIB, and 0.3 wt%-8.0 wt% of a metal oxide of group VIII, by total weight of Catalyst B.
