Problems solved by technology

Among them, the carrier material is prepared by directly adding molecular sieves in the process of forming amorphous silica-alumina. In this way, amorphous silica-alumina is prone to agglomeration, and it is also easy to enter the pores of the other party or block the pores of molecular sieves, which affects the amorphous silica-alumina. The distribution on the molecular sieve, the poor connectivity between the molecular sieve and the amorphous silica-alumina channel, reduces the specific surface area and pore volume of the catalyst, and the distribution of active metals is not easy to control, which makes the hydrogenation function of the catalyst mismatch with the cracking function, affecting the catalyst performance

Abstract

The invention discloses a hydrogenation catalyst composition. The hydrogenation catalyst composition comprises hydrogenation active metal components, molecular sieves and amorphous silica-alumina, wherein the hydrogenation active metal components are mainly loaded on the molecular sieves; the molecular sieves are coated withamorphous silica-alumina; the hydrogenation active metal components account for 1-100% of the molecular sieves by weight in terms of oxide; the weight ratio of the molecular sieves to amorphous silica-alumina is (1:19)-(19:1). The hydrogenation catalyst composition enables the hydrogenation active metals to fully approach the acid centers of the molecular sieves, adjusts the hydrogenation and acid functions and is especially suitable for hydrogenation catalysts with relatively low requirements for acidity and relatively high requirements for hydrogenation properties.
