A process for the catalytic conversion of hydrocarbons to convert petroleum hydrocarbons in a higher yield for light olefins, particularly propylene is disclosed, the process involving a hydrocarbon-converting catalyst comprising zeolite, phosphorous and a transition metal, as defined herein.

Process for the catalytic conversion of hydrocarbons

A process for combining the catalytic conversion of organic oxygenates and the catalytic conversion of hydrocarbons: an organic oxygenate feedstock is contacted with a Y-zeolite containing catalyst to produce a reaction stream, and a coked catalyst and a product stream are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to produce a reaction stream, a spent catalyst and a reaction oil vapor are obtained after separating the reaction stream, and the reaction oil vapor is further separated to give the products such as gas, gasoline and the like; a part or all of the coked catalyst and a part or all of the spent catalyst enter the regenerator for the coke-burning regeneration, and the regenerated catalyst is divided into two portions, wherein one portion returns to be contacted with the hydrocarbon feedstock, and the other portion, after cooling, returns to be contacted with the organic oxygenate feedstock. This process not only reasonably utilizes the excessive thermal energy of the hydrocarbon conversion, but also solves the problem of heat supply for the conversion of the organic oxygenate, thus ensuring the continuous catalytic conversion of the organic oxygenate.
