Catalytic cracking is one of the petroleum refining processes. It is a process of cracking heavy oil into cracked gas, gasoline and diesel under the action of heat and catalyst.
It is one of the main methods of petroleum secondary processing. The process of cracking heavy oil into cracked gas, gasoline and diesel under the action of high temperature and catalyst. The main reactions include decomposition, isomerization, hydrogen transfer, aromatization, condensation, coke formation, etc. Compared with thermal cracking, it has high light oil yield, high octane number of gasoline, good diesel stability, and by-product liquefied gas rich in olefins. In recent years, the molecular sieve cracking catalyst uses silica sol or aluminum sol and other binders to bond the molecular sieve and kaolin together to make a new generation of semi synthetic molecular sieve catalyst with high density and high strength. In addition to rare earth-y molecular sieve, the molecular sieve used also has super stable hydrogen-y molecular sieve and so on. The reaction is carried out in a tubular reactor, which is called riser catalytic cracking.
