Abstract: A method of manufacturing methanol comprising producing a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, allowing reaction of the synthesis gas to take place over a catalyst to produce a crude methanol, separating the crude methanol into unreacted gas and liquid crude methanol, and distilling the liquid crude methanol to separate it into refined methanol and waste water. Carbon dioxide in combustion exhaust gas to be discharged from a reformer is recovered, and that in feeding the carbon dioxide to the upstream side and/or the downstream side of the reformer, part of the unreacted gas is utilized as a purge gas, a portion of which being utilized as a fuel for a combustion device of the reformer, while the balance of the purge gas being utilized as a fuel for other heating sources and/or as an agent for desulfurizating raw gas.

Abstract: A reactor comprises a plurality of triple tubes having reaction tube, inner tube and central tube and disposed in a main body of the reactor, a first supply port formed in the main body and communicated with the central tube, and a second supply port formed in the main body and communicated with an annular space of triple tubes. The raw material introduced from the first supply port is fed into the catalyst layer to permit the reaction of the raw material to take place, and that as the activity of the catalyst is gradually lowered, the quantity of raw material to be fed to the first supply port is correspondingly reduced, and the quantity of raw material corresponding to this reduction of raw material is fed from the second supply port to the catalyst layer charged in the annular space.
