Title:
MULTI-METAL UNSUPPORTED HYDROREFINING CATALYST, PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/103919
Kind Code:
A1
Abstract:
The present invention relates to a multi-metal unsupported hydrorefining catalyst, and a preparation method therefor. The hydrorefining catalyst consists of at least one +three-valent metal oxide, at least one Group VIII metal oxide, at least one Group IVB metal oxide, and at least two group VIB metal oxides. The catalyst contains 10-50 wt.% of Group VIII metal, 1-30 wt.% of Group IVB metal, 1-50 wt.% of +three-valent metal, and 5-80 wt.% of two Group VIB metal by the metal oxide. Also disclosed is an application of the catalyst in the ultra-deep hydrodesulfurization and denitrification of a diesel fraction process: at the temperature of 280-440ºC, the hydrogen pressure of 1-20 MPa, the volume ratio of hydrogen to the diesel fraction of 50-1,000 V/V, and the volumetric air speed of the diesel fraction of 0.1-10h-1, the catalyst can remove sulfur and nitrogen in a model diesel to below 10 ppm.
