Title:
METHOD FOR CONVERTING ETHANOL AND METHOD FOR PRODUCING OTHER HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2023/145941
Kind Code:
A1
Abstract:
(1) A method for converting ethanol which comprises bringing a mixture feedstock including ethylene and ethanol into contact with a catalyst in an adiabatic reactor to obtain a reaction gas including an olefin having three or more carbon atoms, (2) a method for converting ethanol which comprises bringing a mixture feedstock including methanol and ethanol into contact with a catalyst in an adiabatic reactor to obtain a reaction gas including an olefin having three or more carbon atoms, and (3) a method for converting ethanol which comprises bringing a mixture feedstock including ethanol and ethylene into contact with a catalyst in an adiabatic reactor to obtain a reaction gas including an olefin having three or more carbon atoms, separating the reaction gas by a first distillation tower into a fraction A mainly including hydrocarbons having two to three carbon atoms and a fraction B mainly including hydrocarbons having four to six carbon atoms, and recycling at least some of the fraction A as some of the mixture feedstock to the reaction step.
