Abstract

The invention relates to an adsorption desulfurizing method for catalytic cracking gasoline. The method comprises the following steps: S201, carrying out an adsorption desulfurizing reaction between the catalytic cracking gasoline and an adsorption desulfurizing agent under a hydrogen present condition, and obtaining a desulfurization product and an inactivated desulfurizing agent; S202, separating and purifying the adsorption desulfurizing product, thereby obtaining gasoline components with the sulfur content of less than or equal to 10<mu>g.g<-1>. With the adoption of the method provided by the invention, hydrogenation saturation of olefins can be effectively reduced while realizing ultra-deep reaction adsorption desulfurization of high-sulfur inferior catalytic cracking gasoline, and chemical hydrogen consumption and octane loss are reduced. Moreover, the adsorption desulfurizing agent provided by the invention has the advantages of high sulfur capacity, low wear rate, low adsorption reaction temperature, capability of obviously reducing operating cost and the like. Meanwhile, the adsorption desulfurizing agent provided by the invention can realize continuous regeneration on line, so that the defect that the running period of the adsorption desulfurizing agent is low due to inactivation is overcome.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a catalytically cracked gasoline adsorption desulfurizer and a preparation method and application thereof. Background technique [0002] As we all know, with the increasingly serious smog phenomenon in recent years, the environmental pollution caused by vehicle exhaust emissions has become a major problem that must be solved for the sustainable development of the national economy and society. In recent years, my country's gasoline quality upgrade has progressed rapidly. On January 1, 2017, the sulfur content of less than 10 μg g was implemented nationwide. -1 the National V standard. Recently, my country has issued more stringent National VI standards, which are planned to be implemented on January 1, 2019, which poses a great challenge to the development of my country's oil refining industry. The characteristics of my country's oil refining industry are that mor...
