PREPARATION METHOD OF SYNGAS METHANATION CATALYST USING CO GAS AND SYNGAS METHANATION CATALYST PREPARED BY THE METHOD

摘要

The present invention relates to a catalyst for methanizing a synthetic gas and a preparation method thereof. According to the present invention, the preparation method of a direct mathanation catalyst, which is a molybdenum disulfide (MoS2) based catalyst, for a synthetic gas includes the steps of: grinding precursors containing sulfur and molybdenum; mixing the ground precursors with a material including a solvent; reacting the mixed materials obtained by the earlier step under an atmosphere of high pressure CO gas after placing the mixed material in a reactor; and activating the produced catalyst.
