A Heavy Oil Catalytic Cracking Catalyst price and a preparation method thereof, the catalyst comprising an effective amount of REY molecular sieve and a substrate, wherein the preparation method of the REY molecular sieve comprises contacting the NaY molecular sieve with an aqueous solution containing rare earth ions or with an aqueous solution containing a rare earth ion. After the aqueous solution of rare earth ions is contacted with the solution or colloid containing aluminum ions, it is contacted with an external precipitant to precipitate part of the rare earth on the molecular sieve, then hydrothermally treated, and then contacted with an aqueous ammonium salt solution, the matrix contains a transition metal oxide modified. hydrated alumina; the catalyst is prepared by beating REY molecular sieve and matrix and spray-drying.
The above is a brief introduction to the knowledge of Heavy Oil Catalytic Cracking Catalyst price and preparation methods.
