Abstract

An investigation of the effects of catalytic properties and position of carbon deposition in CO2 reforming of methane under high pressure on NiO-MgO (Ni0.03Mg0.97O) solid solution catalyst showed that this catalyst exhibited very stable activity without carbon deposition under 1 atm. A commercial steam reforming catalyst (G-91) was also studied as a reference. A large amount of carbon was observed on the commercial catalyst, particularly at the inlet of the reactor, suggesting that carbon could be formed from methane decomposition. The amount of carbon observed on the solid solution catalyst was much less than that observed on the commercial catalyst. More carbon was deposited on the catalyst at the catalyst bed's outlet than that at the inlet, indicating that the formation of carbon from methane on Ni0.03Mg0.97O was inhibited, but the formation of carbon from CO was enhanced and became dominant.
