<P>PROBLEM TO BE SOLVED: To provide an efficient process for removing carbon monoxide, which is easy to control its reaction temperature and does not generate a run away reaction. <P>SOLUTION: A methanation process of carbon monoxide comprises bringing a catalyst for carbon monoxide methanation into contact with a hydrogen gas containing carbon monoxide gas, wherein a first reactor is connected with a second reactor, the reaction temperature (T<SB>1</SB>) of the first reactor is in the range of 170-250°C, the reaction temperature (T<SB>2</SB>) of the second reactor is in the range of 100-170°C and the reaction temperature difference (T<SB>1</SB>)-(T<SB>2</SB>) is in the range of 20-150°C. <P>COPYRIGHT: (C)2008,JPO&INPIT |
