Abstract
A method for catalytic cracking of naphtha is provided. Naphtha is catalytically cracked under the action of a catalyst. The catalyst includes aluminosilicate, alkali metal oxide, alkaline earth metal oxide, TiO, iron oxide, vanadium oxide and nickel oxide. On the other hand, a rapid separation component is arranged in a disengager of a catalytic cracking reaction device, so that a transport disengaging height is greatly reduced without changing a gas flow and a diameter of the disengager. In addition, the separation efficiency of oil gas and the catalyst is improved.
