Beschreibung
Zusammenfassung:	The present invention relates to a naphtha raw material catalysis cracking method, which comprises that: (1) a naphtha raw material contacts a first catalysis cracking catalyst in a first reaction zone, and a reaction is performed to obtain a first oil agent mixture; and (2) the first oil agent mixture and a second catalysis cracking catalyst are introduced into a second reaction zone to react, wherein the reaction temperature of the second reaction zone is higher than the reaction temperature of the first reaction zone, and the temperature of the second catalysis cracking catalyst is higher than the temperature of the first catalysis cracking catalyst. According to the present invention, with the naphtha raw material catalysis cracking method, the yields of ethylene and propylene can be improved while the yields of the non desired products such as hydrogen, methane and coke are not changed or are not reduced.
