METHOD FOR PRODUCING OLEFINS HAVING CARBON NUMBER OF THREE OR MORE FROM ETHANOL

摘要

PROBLEM TO BE SOLVED: To provide an industrially extremely advantageous method for producing propylene from ethanol, which produces propylene under a relatively mild reaction condition in high selectivity and easily reproduces a deactivated catalyst.

SOLUTION: In the method for producing a ≥3C olefin, especially propylene from ethanol in the presence of a catalyst, a catalyst comprising iron, phosphorus and zeolite is used as the catalyst. H-ZSM-5 type zeolite having a low silica-alumina ratio is used as a zeolite analog. Water-containing ethanol is used as the ethanol.
