Abstract
The supporter material for catalyst includes a main body alumina and a rod-shaped alumina. The main body alumina is provided with micron-sized pore channels, at least part of the rod-shaped alumina is distributed on the exterior surface of the main body alumina and/or in the micron-sized pore channels with a pore diameter D within a range of 3-10 μm; the rod-shaped alumina has a length of 1-12 μm and a diameter of 80-300 nm. The alumina supporter material is used as a residual oil hydrogenation catalyst supporter to facilitate a long period operation of the residual oil hydrogenation, and has high demetalization rate, desulfurization rate and denitrification rate.
