METHOD FOR PRODUCING UNSATURATED HYDROCARBON USING METAL-CONTAINING ZEOLITE CATALYST

摘要

A method for producing a low-grade olefin having ethylene and propylene as the principal components thereof according to an embodiment of the present invention is characterized by contacting: a metal-containing zeolite catalyst having, as constituent elements thereof, a metal (X) selected from the group 8-10 metals of the periodic table, and a medium-pore zeolite (Z1) having a 10-membered ring structure comprising ten of a tetrahedral TO4 (T=Si or Al) unit; a material (O) having, as the principal component thereof, a saturated hydrocarbon having a boiling point in the range of 35-180°C at 1 atm; and an acidic gas (S).
