Problems solved by technology

FCC catalyst plays a role in promoting the reaction in the chemical reaction and speeds up the chemical reaction rate, but it does not increase the yield of the product. In the process of fluidized catalytic cracking, due to many factors affecting the yield of the product, currently on the market Additives are not very helpful to increase the yield of fluid catalytic cracking products

Abstract

The invention relates to the technical field of additives and in particular relates to an auxiliary agent for improving the yield of a fluidized catalytic cracking product. The auxiliary agent comprises a carrier and an active component, wherein the carrier is a diesel oil solution of porous carbon modified by graphene oxide; the active component is mixed rare-earth metal oxide; the auxiliary agent can be used for improving the yield of the fluidized catalytic cracking product by 20 to 30 percent; a production method is relatively convenient and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to an additive for improving the yield of fluidized catalytic cracking products. Background technique [0002] FCC (Fluid Catalytic Cracking, Fluid Catalytic Cracking) is an important method of producing petroleum. This process converts heavy raw materials, such as vacuum distillate, residue and deasphalted oil, into light products rich in olefins and aromatics. FCC catalyst plays a role in promoting the reaction in the chemical reaction and speeds up the chemical reaction rate, but it does not increase the yield of the product. In the process of fluidized catalytic cracking, due to many factors affecting the yield of the product, currently on the market Additives do not help much to increase the yield of fluid catalytic cracking products. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention p...
