Abstract
The effect of steam on stability, catalytic activity and selectivity of platinum catalyst supported on zirconia in CO2 reforming of methane under 2.1 MPa pressure was studied. The results showed that the addition of steam into CH4-CO2 system was an effective method to prohibit coke formation and increase the stability of the catalyst. Syngas with n(CO)/n(H2)≈1. was obtained when n(H2O)/n(CH4) was close to 1.0 under the conditions of n(CO2)/n(CH4)=2, θ=800°C and p=2.1 MPa.
