  • Process for producing ethylene from ethanol combining the catalytic conversion of hydrocarbons
    Patent number: 8273930
    Abstract: A process for producing ethylene from ethanol combining the catalytic conversion of hydrocarbons: an ethanol feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, and a coked catalyst and an target product of ethylene are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, a spent catalyst and an oil vapor are obtained after separating the reaction stream, and the 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 ethanol feedstock.
