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.
摘要:
A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a catalyst comprising iron oxide and alumina to form a heavy hydrocarbon slurry and hydrocracked to produce lighter hydrocarbons. The iron sulfide crystallites have diameters in the nanometer range.

摘要:
A treated decomposable compound of molybdenum, which has been prepared by the catalytic dehydrogenation of a decomposable compound of molybdenum wherein the molybdenum has a valence state greater than zero or by the treating of the decomposable compound of molybdenum with a reducing agent, is mixed with a hydrocarbon-containing feed stream. The hydrocarbon-containing feed stream containing such treated decomposable compound of molybdenum is then contacted with a catalyst composition comprising a support selected from the group consisting of alumina, silica and silica alumina and a promoter comprising at least one metal selected from the group consisting of Group VIB, Group VIIB, and Group VIII of the Periodic Table to reduce the concentration of metals, sulfur, nitrogen, Ramsbottom carbon residue and/or heavies contained in the hydrocarbon-containing feed stream.
