Abstract

The invention relates to a heavy-oil hydrogenating catalyst and application thereof. The heavy-oil hydrogenating catalyst contains a carrier and a hydrogenating active metal component, wherein the carrier is prepared by the step of roasting a boric pseudoboehmite; based on the dry basis of the pseudoboehmite, the content of boron (boron oxide) in the pseudoboehmite is 1-10wt%; the pseudoboehmite contains at least one pseudoboehmite P1 meeting the relation that n is more than or equal to 1.1 but less than or equal to 2.5; n is equal to D(031) / D(120); the D(031) represents a grain size of a crystal surface represented by peak 031 in an XRD (X-Ray Diffraction) spectrogram of pseudoboehmite grains; the D(120) represents the grain size of the crystal surface represented by peak 120 in the XRD spectrogram of pseudoboehmite grains; the peak 031 is a peak with a 2theta being 34-43 degrees in the XRD spectrogram; the peak 120 is the peak with the 2theta being 23-33 degrees in the XRD spectrogram; D is equal to K Lambda / (Bcos theta); K is Scherrer constant; Lambda is a diffraction wavelength of a target material; B is a half-peak width of a refraction peak; and 2theta is the position of therefraction peak.

Description

field of invention [0001] The invention relates to a hydrogenation treatment catalyst and its application, in particular to a heavy oil hydrogenation treatment catalyst and its application. Background technique [0002] With the increasing scarcity of petroleum resources, the contradiction between heavy crude oil and light products has become increasingly acute. Oil refining companies around the world are vigorously developing catalytic cracking (RFCC) technology and coking and other thermal cracking technologies for blending or fully refining residual oil. , of which the RFCC process has become the most effective process for lightening heavy oil. However, the high content of impurities in the residual oil, such as sulfur, nitrogen, metals and residual carbon, has a greater impact on the stable operation of the RFCC process unit. In order to increase the adaptability of residual oil feed to the RFCC unit, as the raw material pretreatment unit of the RFCC unit, the impurity ...
