SYSTEM FOR SYNTHESIZING LIQUID FUEL

摘要

A liquid-fuel synthesis system which comprises: a gas purification apparatus (102) in which the composition of a synthesis gas comprising hydrogen and carbon monoxide or of a synthesis gas comprising hydrogen, carbon monoxide, and carbon dioxide is regulated to obtain a purified gas; and a liquid-fuel synthesis apparatus (300) in which the purified gas (301a) obtained with the gas purification apparatus is used as a feed material to synthesize a liquid fuel (309). The gas purification apparatus has a hydrogen separator (120) and a by-pass line (406) bypassing the hydrogen separator. The system has a constitution in which high-purity hydrogen (j) obtained by passing part of the synthesis gas through the hydrogen separator is mixed with the synthesis gas which has passed through the by-pass line to thereby regulate the proportions of hydrogen and carbon monoxide or of hydrogen, carbon monoxide, and carbon dioxide in the purified gas.
