ALUMINUM OXIDE CARRIER MATERIAL AND PREPARATION METHOD THEREFOR, HYDROGENATION CATALYST AND METHOD FOR RESIDUAL OIL HYDROGENATION

WIPO Patent Application WO/2019/080921

A1

Disclosed are an aluminum oxide carrier material and a preparation method therefor, a hydrogenation catalyst and a method for residual oil hydrogenation. The carrier material comprises main body aluminum oxide and rod-like aluminum oxide, wherein the main body aluminum oxide has micron grade channels, and at least part of the rod-like aluminum oxide is distributed on the external surface of the main body aluminum oxide and/or in the micron grade channels with a channel diameter D of 3-10 μm. An aluminum oxide carrier intermediate is first prepared, then immersed in an ammonium bicarbonate solution for a heat sealing treatment, and is subjected to drying and calcination so as to obtain the aluminum oxide carrier material. The carrier material can be used as a catalyst carrier for residual oil hydrogenation, and the material has a long running period, and a very high demetalizing rate, desulfurization rate and denitrogenation rate.
