摘要： A reaction vessel has a catalytic core, with an inlet for a first gas and for a second gas. The first and second gasses react in an exothermic reaction during passage through the catalytic core. The first gas passes through conduits which extend through the catalytic core, so as to be preheated and also so as to cool the catalytic core so that the catalyzed reaction proceeds in a preferred temperature range. The gasses are mixed at one end of the vessel in a mixing chamber, and are drawn through the catalytic core into a gathering chamber, from which the reacted gasses exit. A cooling chamber is provided for introduction of a cooling fluid about the periphery of the catalytic core, for drawing away any excess heat during operation.

A steam-containing natural gas is prepared by adding stream to a natural gas. The steam-containing natural gas is preheated by passing the natural gas through a convection portion of reformer, the natural gas preheated being subsequently fed to the reaction tube. After being preheated in the convection portion, carbon dioxide is fed to the reaction tube, thereby producing a synthesis gas containing hydrogen and carbon monoxide.

摘要： A method of manufacturing a synthesis gas containing hydrogen and carbon monoxide comprises steps of removing only hydrogen sulfide from a natural gas containing hydrogen sulfide and carbon dioxide by permitting the natural gas to pass through a hydrogen sulfide-removing device filled with a hydrogen sulfide absorbent, adding carbon dioxide and steam to the natural gas which the hydrogen sulfide has been removed to prepare a mixed gas, and feeding the mixed gas into a reaction tube of a reformer, thereby permitting mainly a steam reforming reaction to take place in the mixed gas. This method enables hydrogen sulfide in natural gas to be removed while permitting the carbon dioxide of natural gas to be effectively utilized, thereby reducing the quantity of carbon dioxide to be added to the natural gas to be transferred to the reformer.

摘要： A natural gas having steam and carbon dioxide added thereto is supplied into a reaction tube of a reformer provided with the reaction tube and a combustion radiation section for heating the reaction tube by combustion of a fuel so as to carry out a reaction between the hydrocarbon contained in the natural gas and the steam added to the natural gas, thereby forming a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide. Then, the synthetic gas is subjected to a reaction in the presence of a methanol synthesizing catalyst. A crude methanol obtained is subjected to a gas-liquid separation. Further, a liquid crude methanol separated in the separation is distilled. In the particular methanol manufacturing process, a part of the purge gas obtained in the separation is recycled into the natural gas having steam and carbon dioxide added thereto in advance.
