Problems solved by technology

[0004] However, the utilization rate of rare earth elements in petroleum processing catalysts that introduce rare earth elements in the prior art is low. Under the premise of shortage of rare earth elements, it is necessary to use rare earth elements with the highest efficiency to prepare petroleum processing catalysts with high activity and stability.
[0005] In addition, the existing catalysts for petroleum processing that introduce rare earth elements have a short lifespan, which further leads to the inability of the rare earth elements to be fully utilized

Abstract

The invention discloses a petroleum processing catalyst and a preparing method thereof. The petroleum processing catalyst is prepared from, by weight, 1-4 parts of lanthanum oxide, 1-5 parts of lanthanum nitride, 22-40 parts of lithium oxide, 12-35 parts of graphene, 12-28 parts of sodium phosphate, 8-22 parts of calcium silicate, 25-40 parts of acetic acid and 22-44 parts of absolute ethyl alcohol. Rare earth element and neutral salt are combined, the petroleum processing catalyst which is obtained through pulverization, pickling, high-temperature calcination and other processes has the advantages of being high in activity and stability and long in service life.

Description

technical field [0001] The invention relates to a catalyst material, in particular to a petroleum processing catalyst and a preparation method thereof. Background technique [0002] The catalytic cracking reaction in the petroleum processing process is to catalytically crack large molecular hydrocarbon molecules into small molecular hydrocarbon molecules, that is, to convert heavy oil into light oil, which is the most critical secondary processing step of petroleum. Including the following three steps: cracking, isomerization and hydrogen transfer. [0003] The introduction of rare earth elements as an important component into the cracking catalyst can significantly improve the activity and stability of the catalyst, greatly increase the cracking conversion rate of feedstock oil, and increase the yield of gasoline and diesel. At the same time, it also has the advantages of large crude oil treatment capacity, high light oil yield, low coke formation rate, low catalyst loss a...
