CATALYST FOR METHANATION METHOD FOR PREPARING THE SAME AND METHOD FOR PREPARING SYNTHETIC NATURAL GAS USING THE SAME

摘要

The present invention is based on 100 parts by weight of the catalyst, Ni 10 to 70 parts by weight, Ba, Sr, Na, K, Rb, Cs, Mg and Ca selected from the group consisting of one of the cocatalyst 0.5 to 7 parts by weight and metal It relates to a methanation catalyst having excellent hydrothermal reforming reaction including the remainder of the support. According to the present invention, by using synthetic gas containing C5 or more hydrocarbons larger than LPG (C2, C3, and C4 hydrocarbons), the carbon deposition occurring in the methanation reaction during synthesis natural gas production is reduced, and CO ₂ production reaction is suppressed. A methanation catalyst is provided. In addition, by producing a synthetic natural gas using the methanation reaction catalyst, there is an effect that can increase the yield of the synthetic natural gas.
