[0002] Catalytic cracking is a process of producing liquefied gas, gasoline and diesel oil and other light oil products from heavy petroleum hydrocarbons under the action of catalysts. When the raw oil is catalytically cracked on the catalyst, on the one hand, gas, gasoline, diesel oil and other products are generated through cracking and other reactions, and on the other hand, a condensation reaction occurs to generate coke deposited on the surface of the catalyst, which reduces the activity of the catalyst.
