On the Stability of Ni Catalyst for Methane Reforming with CO2 and H2O Under Pressure
Abstract:
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.
