Abstract

The invention provides a catalyst having a hydrogenation catalysis effect, and a preparation method and an application thereof. The catalyst contains a support, and at least one group VIII metal element and at least one group VIB metal element which are supported on the support, the at least one group VIII metal element and the at least one group VIB metal element are respectively non-uniformly distributed along the radial cross section of the catalyst, wherein the support is a molded siliceous hydrated alumina along the radial cross section of the catalyst, and is prepared through using raw materials containing at least one hydrated alumina, at least one siliceous compound and at least one cellulose ether. The invention also provides a hydrocarbon oil hydrotreatment method. The catalyst has a high catalysis activity, a good catalysis stability and a long service life in the hydrogenation and metal removal reaction of hydrocarbon oil (especially heavy hydrocarbon oil).

Description

technical field [0001] The invention relates to a catalyst with hydrogenation catalysis, its preparation method and application, and also relates to a hydrogenation treatment method. Background technique [0002] In addition to sulfur and nitrogen, heavy oil also contains a large amount of metal impurities such as Ni, V, Fe, Ca, asphaltene and colloid. During the hydrotreating process of such raw oil, these impurities will be adsorbed on the surface of the catalyst to cover the active centers or deposited in the pores of the catalyst to block the pores, thereby causing the deactivation of the catalyst. Therefore, the metal storage capacity and anti-coking performance of the catalyst used in the heavy oil hydrotreating process will directly affect the service life of the catalyst. [0003] US4760045 discloses a heavy oil hydrotreating catalyst, which contains a porous heat-resistant oxide carrier and at least one element selected from Group VB, Group VIB and Group VIII of th...
