上記の触媒は、公知の担持方法によって調製される。例
えば硝酸塩等の水溶液に固型活性炭を懸濁させ、水を蒸
発させた後、乾燥、さらに不活性ガス中で熱分解する。The above catalysts are prepared by known support methods. For example, solid activated carbon is suspended in an aqueous solution of nitrate or the like, and after the water is evaporated, it is dried and then thermally decomposed in an inert gas.
この触媒をＮ２またはｃ。This catalyst was heated with N2 or c.
ガス中で部分還元した後に使用するが、目的実ガス（本

。The actual target gas (CO gas before being purified in the method of the present invention) is heated at 100° C. after being partially reduced in a gas.
Even if it is pre-reduced by flowing it at a certain level, the catalytic ability is sufficiently exhibited.
添着活性炭が一度部分還元されると、反応温度を室温か
ら６０℃程度まで下げても充分に触媒反応が進行する。Once the impregnated activated carbon is partially reduced, the catalytic reaction proceeds sufficiently even if the reaction temperature is lowered from room temperature to about 60°C.
本発明法の添着活性炭を原料ガスと接触させる温度は室
温〜１５０℃、より好ましくは５０〜８０℃である。The temperature at which the impregnated activated carbon of the present invention is brought into contact with the raw material gas is from room temperature to 150°C, more preferably from 50 to 80°C.

二酸化炭素はほとんどの場合、合成反応には無害であり
、少量でもあるので特に除去する必要はない。In the method of the present invention, carbon dioxide is produced between the main component carbon monoxide and a trace amount of oxygen using the above-mentioned catalyst, and trace amounts of chlorine, etc. are adsorbed and removed. In most cases, it is harmless to the synthesis reaction and is present in small amounts, so there is no need to remove it.

ことによるものであろう。The above-mentioned catalyst using impregnated activated carbon used in the method of the present invention stably exhibits high deoxidation activity even at lower reaction temperatures than conventionally known copper-based catalysts, and at the same time has long-lasting functions as a dechlorination and desulfurization compound. It has the characteristic of indicating a period. This is probably because the surface area of this catalyst is very large, so chlorine and the like are mainly adsorbed on the activated carbon surface, making it difficult for them to combine with copper, which is important for deoxidation.
