摘要
The present invention relates to a catalyst for producing synthetic natural gas (SNG) in which methanation reaction and fischer-tropsch synthesis are progressed at the same time, and a manufacturing method thereof and, more specifically, to a catalyst for producing a high calorific methane gas comprising: 30-90 parts by weight of a metal support; and a catalyst activating ingredients including 10-70 parts by weight of nickel and 1-10 parts by weight of one metal element selected from Fe, Co, Zr, Ce and Ga. The manufacturing method for the catalyst comprises: a catalyst active ingredient producing step; and an impregnating step of impregnating the catalyst activating ingredients into the metal support. The present invention increases the yield of carbon (C) by performing the process in conditions in which the H_2/CO ratio of syngas supplied to methanation reaction is lower than 3.0 since methanation reaction and fischer-tropsh synthesis occur at the same time by using the catalyst in a manufacturing method for synthetic natural gas (SNG), exhibits excellent reproducibility by allowing high calorific synthetic natural gas to be produced and provides the catalyst for synthesizing high calorific methane through a simple manufacturing process.
