Abstract

The invention provides a catalyst with a hydrogenation catalytic function, a preparation method, and applications thereof. The catalyst comprises a carrier, at least one metal selected from the VIII group metals, and at least one metal selected from the VIB group metals, wherein the metals are loaded on the carrier; the VIII group metal element and the VIB group metal element are individually and unevenly distributed along the radial cross section of the catalyst, wherein along the radical cross section of the catalyst, a formula is represented in the description, and the carrier is a hydrate alumina forming product, which is prepared from following raw materials: at least a hydrate alumina, at least a compound containing magnesium, and at least a cellulose ether. The invention also provides a hydrogenation processing method of hydrocarbon oil. The catalyst provided by the invention has a higher catalytic activity, a better catalytic stability, and a longer service life in the hydrogenation and metal-removing reactions 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, the catalyst contains a porous refractory oxide carrier and at least one element selected from Group VB, Group VIB and Group VIII of...
