The liquid fuel synthesis system according to the present invention includes a gas purifying apparatus ( 102 ) for adjusting components of a synthesis gas containing hydrogen and carbon monoxide or a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide to produce a purified gas, and a liquid fuel synthesis apparatus ( 300 ) for synthesizing a liquid fuel ( 309 ) using, as a raw material, the purified gas ( 301 a ) produced in the gas purifying apparatus. The gas purifying apparatus includes a hydrogen separating apparatus ( 120 ) and a bypass line ( 406 ) which bypasses the hydrogen separating apparatus. A part of the synthesis gas is passed through the hydrogen separating apparatus to produce high-purity hydrogen (j), and the produced high-purity hydrogen (j) is mixed with the synthesis gas which has passed through the bypass line to adjust the ratio of hydrogen to carbon monoxide in the purified gas or the ratio between hydrogen, carbon monoxide and carbon dioxide in the purified gas. |
