Zusammenfassung:	PROBLEM TO BE SOLVED: To provide technology suitable for production of liquefied petroleum gas using synthesis gas derived from a carbon-free raw material, such as biomass.SOLUTION: The composition of gas supplied to a reforming reactor 4 is measured by a measurement part 9, so that an H/CO molar ratio is calculated. The opening of a flow control valve 8 is controlled so as to have the H/CO molar ratio of 2/1, the optimal reaction condition, based on the calculation result. Therefore, the Hflow rate recycled to the piping L13 side through a recirculation system 18 is adjusted. The rest of the Hseparated and recovered by a hydrogen-separating device 13 is passed to the piping L12 side and utilized as fuel for heating a heat source.
