Abstract
A raw material gas containing hydrocarbon as a main component is supplied together with steam to a reformer through a moistening device to form a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide as main components by the reaction between the hydrocarbon contained in the raw material gas and the steam. In forming the synthetic gas, carbon dioxide is supplied to at least one fluid passageway selected from the group consisting of the fluid passageway positioned upstream of the moistening device and the fluid passageway interposed between the moistening device and the reformer. As a result, the excess hydrogen contained in the gas formed in the reformer is effectively utilized without bringing about deactivation of the methanol synthesizing catalyst in the methanol synthesizing step. Also, carbon dioxide is effectively utilized to decrease the amount of carbon dioxide discharged to the outside of the system. Further, it is possible to decrease the amount of steam supplied to the reformer.
