1. A liquid fuel synthesis system comprising:
a liquid fuel synthesis portion having a separation membrane permeable to water vapor which is a by-product of a conversion reaction of a raw material gas containing hydrogen and carbon oxide to a liquid fuel, the liquid fuel synthesis portion being partitioned into a non-permeation side space and a permeation side space by the separation membrane; and
a sweep gas supply unit configured to supply the permeation side space with a sweep gas for sweeping the water vapor permeating through the separation membrane; wherein
a temperature of the sweep gas flowing into the permeation side space is higher than at least one of the temperature of the raw material gas flowing into the non-permeation side space and the temperature of a first outflow gas flowing out of the non-permeation side space, and
a temperature of a second outflow gas flowing out of the permeation side space is higher than at least one of the temperature of the raw material gas flowing into the non-permeation side space and the temperature of the first outflow gas flowing out of the non-permeation side space.
