The reaction of methane with CO₂ and H₂O using catalyst MCD-2(α-Al₂O₃ with 15%~17% impregnated NiO) has been investigated. After a 500 h continuous run underconditions: n (CH₄): n (CO₂): n (H₂O)=1:1.5:0.9, CH₄ space velocity 1000 h ^-1, bed temperature 600~900℃ and 0.6 MPa, it is found that the porous structure, mechanical strength,content of active nickel,XRD patterns and content of deposited carbon on the catalyst did not change drastically and the activity of the catalyst kept steady with the CH₄ conversion,CO content on the product gas and H₂/CO ratio being ≥92%, ~40% and ~1, respectively.
