Problems solved by technology

[0009] Due to the small pores of traditional microporous molecular sieves, it shows an obvious effect of restricting the diffusion of larger raw material molecules, especially when some pores are blocked by heavy metals, making it difficult for pure microporous molecular sieves to be suitable for blending with high iron content. Catalytic cracking of tight oil requires the use of molecular sieve materials with large pore size and no diffusion limitation for reactant molecules

Abstract

The invention discloses a catalytic cracking catalyst for blending tight oil and a preparing method thereof. The catalyst is prepared from a first molecular sieve component, a second molecular sieve component, modified pseudo-boehmite, pseudo-boehmite, clay and a binding agent. The catalytic cracking catalyst has the advantage of having a large matrix specific area, shows up high catalytic cracking activity in the process of conducting a catalytic cracking reaction on raw oil used for blending the tight oil and has a high conversion rate in the process of conducting catalytic cracking treatment on the tight oil (the basic nitrogen content of mixed oil is about 1200-2000 micrograms / g) with high blending basic nitrogen compound content, a high gasoline and diesel oil yield can be obtained, and particularly the yield of light oil like gasoline is high.

Description

technical field [0001] The invention relates to the technical field of catalysts, in particular to a catalytic cracking catalyst blended with tight oil and a preparation method of the catalytic cracking catalyst. Background technique [0002] Fluid catalytic cracking, as an important means of secondary processing of crude oil, occupies a pivotal position in the oil refining industry, and every small progress of it will bring huge economic benefits to the enterprise. Fluid catalytic cracking catalyst is one of the technical cores of the catalytic cracking process, and its technological progress is also an important means for the fluid catalytic cracking process to obtain the maximum benefit. [0003] In the catalytic cracking process, heavy fractions such as vacuum distillate oil or residues of heavier components react in the presence of catalysts to convert them into high value-added products such as liquefied gas, gasoline, and diesel. With the increasing depletion of pe...
