EFFECTS OF SUPPORTS ON THE ACTIVITY OF NICKEL CATALYST FOR CH4 REFORMING WITH CO2

摘要: ABSTRACT Nickel catalyst is an effective for reforming CH4 with CO2. The reaction between CO2 and at 1073 K. in the pressure of 0·1 MPa has been studied over different materials supported nickel metal a fixed-bed reactor. Different catalysts before after were characterized by SEM, XRD, XPS. Results shows that CO H2 are basically produced same ratio. When feed ratio CO2/CH4 less than 0·5, C2˜C4 hydrocarbons detected. 1, Ni/a- Al2O3 highest activity. However, when greater Ni/y- A1/O3, A12O3, Ni/SiO2 Ni/HZSM-5 had higher activity; Ni/clinoptilolite no kinds carbon deposit established.
