A preparation method of quality Heavy Oil Catalytic Cracking Catalyst products used in petroleum processing, specifically a kind of quality Heavy Oil Catalytic Cracking Catalyst products with high yield of diesel oil and a preparation method thereof. The method is to combine molecular sieve, pseudoboehmite, clay , Mineral acid and deionized water are beaten and mixed evenly, and aluminum sol is added or not added at the same time to make catalyst slurry, which is then spray-dried, calcined, and then washed with ammonium sulfate and ammonium dihydrogen phosphate solution, and finally dried to obtain Catalyst. Adopting the method of the present invention can effectively control the degree of peptization of pseudo-boehmite, so as to avoid the influence of the pore volume of the catalyst by the fluctuation of the acid amount of pseudo-boehmite. Compared with the prior art, the method provided by the present invention, It can increase the pore volume of the catalyst and improve the heavy oil cracking capacity and diesel yield of the catalyst.
The above is a brief introduction to the little knowledge about quality Heavy Oil Catalytic Cracking Catalyst products.
