Description

technical field [0001] The disclosure relates to a zirconium-aluminum hollow sphere prepared by using FCC waste catalyst as a raw material and its production process and application. Background technique [0002] The information disclosed in this Background section is only intended to increase the understanding of the general background of the disclosure, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes prior art that is already known to those skilled in the art. [0003] Catalytic cracking (FCC) catalyst is an indispensable catalyst for modern petroleum refining process, which can crack petroleum raw materials into cracked gas, gasoline and diesel oil, especially for domestic oil refining enterprises. During the use of FCC catalyst, due to the deposition of heavy metal elements and other inorganic elements on the surface of the catalyst, the activity and selectivity of the catalyst will be reduced, and even p...
