A catalyst for producing a liquefied petroleum gas according to the present invention comprises a Pd-based methanol synthesis catalyst component and a .beta.-zeolite catalyst component. It can be used in a reaction of carbon monoxide and hydrogen to give a hydrocarbon containing propane or butane as a main component, i.e., a liquefied petroleum gas, with high activity, high selectivity and high yield. Furthermore, the catalyst has a longer catalyst life with less deterioration.
