A synthetic gas containing hydrogen and carbon monoxide can be efficiently obtained by reacting a hydrocarbon feedstock gas with carbon dioxide under pressure, while suppressing carbon deposition. Carbon dioxide reforming of a hydrocarbon feedstock gas is performed under pressure conditions of 3 atmospheres (0.304 MPa) or more using a carbon dioxide reforming catalyst that contains a carbonate of at least one alkaline earth metal selected from the group consisting of Ca, Sr, and Ba, a catalytic metal promoting the decomposition reaction of a hydrocarbon feedstock gas, at least one alkaline earth metal selected from the group consisting of Ca, Sr, and Ba, and a complex oxide containing at least one component selected from the group consisting of Ti, Al, Zr, Fe, W, and Mo. The complex oxide is ATiO 3 , AAl 2 O 4 , AZrO 3 , AFe 2 O 4 , A 3 W 2 O 9 , A 2 WO 5 , or AMoO 4 (wherein A is at least one alkaline earth metal selected from the group consisting of Ca, Sr, and Ba). |
