METHOD FOR PRODUCING CATALYST FOR OLEFIN PRODUCTION, CATALYST FOR OLEFIN PRODUCTION, AND METHOD FOR PRODUCING OLEFIN

摘要

PROBLEM TO BE SOLVED: To provide: a method for producing a catalyst for producing an olefin capable of stably producing the olefin having at least one more carbon atom than the alcohol using an alcohol as a raw material at a high yield for a long time; a catalyst for producing the olefin; and a method for producing the olefin.SOLUTION: A method for producing a catalyst for producing olefin having at least one more carbon atom than the alcohol from an alcohol comprises: a precipitating step wherein a precipitant is introduced into an aqueous solution that contains an indium salt until the pH reaches 8.0 or more so as to form a precipitation containing indium; an aging step wherein the resulting material is subjected to aging at 30°C or less for 25 hours or more after the completion of the precipitant introduction; and a firing step wherein firing is carried out at 500-1,000°C after the aging step. A catalyst for olefin production, which is produced by the production method; and a method for producing an olefin, which uses the catalyst.
