ABSTRACT:
At least one selected from the group consisting of methanol and dimethyl ether, and hydrogen are reacted in the presence of a catalyst for producing a liquefied petroleum gas in which an olefin-hydrogenation catalyst component is supported on a zeolite, to produce a hydrocarbon containing propane or butane as a main component, i.e., a liquefied petroleum gas.
