The utility model belongs to the catalyst field relates to the used catalyst of methanation reaction in the coal -based natural gas technology, specifically is a four hole double arc face catalyst. This catalyst appearance is cylindric, and two bottom surfaces of cylinder are arc, and the inside axial of cylinder has four evenly distributed's a column pore, and column pore transversal is personally submitted circularly. The centre of a circle that the four hole double arc face catalyst cross section was used in four evenly distributed's column pore is square evenly distributed on the cross section of catalyst as the center. The utility model discloses four hole double arc face catalyst has increased the external surface area of catalyst, has reduced the resistance of air current in the bed, reduces the bed differential pressure, has reduced system energy consumption, has solved the contradiction between activity and the differential pressure, improves the catalyst availability factor, and catalyst intensity is high and loads portably.
