Abstract

The invention relates to an auxiliary capable of increasing clean oil yield and used for catalytic cracking, which is composed of the following components by weight percentage: 5-15% of dispersing agents, 10-25% of antioxidant, 5-15% of metal ion deactivation agents, 20-35% of mixed rare earth and the balance solvents. By adding the auxiliary in a catalytic cracking system, carbonium ion reaction can be promoted, generation of side reactions such as thermal cracking reaction and dehydrogenation condensation reaction can be restrained, generation of by-products such as dry gas and hard coke is reduced, and yield of products with high additional value such as liquefied gas, gasoline and diesel oil is improved. The auxiliary has the function of a metal passivator and can replace the metal passivator. The auxiliary can effectively passivate metallic nickel and vanadium metal, reduces dehydrogenation activity of the metallic nickel and vanadium metal, accordingly reduces depositing of scaling materials on surfaces of a catalyst, prolongs service life of the catalyst, enables devices to operate for a long time, and is a multifunctional oil soluble liquid auxiliary for catalytic cracking.

Description

technical field [0001] The invention belongs to the field of catalytic cracking (FCC) of oil refining technology, and particularly relates to an auxiliary agent for catalytic cracking to increase the yield of light oil. Background technique [0002] Catalytic cracking is one of the important links in the petroleum refining process. It is a process in which heavy oil undergoes a cracking reaction under the action of heat and a catalyst, and is converted into cracked gas, gasoline and diesel oil. Among them, the gasoline yield and diesel yield are The sum is called light oil yield, and the sum of light oil yield and liquefied gas yield is called total liquid yield. The distribution of catalytic cracking products pursued by refineries should be as high as possible light oil yield or The total liquid is collected to achieve the greatest economic benefit. [0003] Since the 1980s, FCC has developed from traditional wax oil cracking to residual oil cracking, and the amount of sla...
