Abstract

The invention relates to the field of treatment and application of hazardous wastes, and discloses a reactivation method of a waste catalytic cracking catalyst, and application thereof. The reactivation method comprises the following steps: 1) roasting waste catalytic cracking catalyst to obtain a roasted product; and 2) carrying out ultrasonic treatment on the roasted product obtained in the step 1) in the presence of water. Through the method provided by the invention, the method for reactivating the waste catalytic cracking catalyst, which is simple, efficient and beneficial to industrial amplification application, and the application of the method can be provided, the micro-reactivity of the reactivated catalyst can be improved, and the stability of the micro-reactivity is high.

Description

technical field [0001] The invention relates to the field of treatment and application of hazardous waste, in particular to a method for reviving a spent catalytic cracking catalyst and its application. Background technique [0002] Catalytic cracking (FCC) catalyst consumption occupies a very large proportion in the entire petroleum refining. During the long-term use of catalytic cracking catalysts in the petroleum refining process, the accumulated carbon will be deposited in the pores of the catalyst and occupy the active sites, seriously affecting the quality of catalytic cracking products. In addition, crude oil, especially heavy oil, contains many heavy metal elements. In the process of petroleum refining, the surface of the catalyst will be attached by heavy metals in the raw material. Vanadium will form vanadate, while iron and nickel will reduce the dehydrogenation ability of the catalyst and reduce the efficiency of the catalyst. There are also some toxic and harm...
