The reaction of methane with CO2 and H2O using catalyst MCD-2(a-Al2O3 with15%~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,tem temperature 600~900℃ and 0. 6 MPa, it is found that the porous structure, mechanicalstrength,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 ~1respectively. 展开更多
