Abstract

Ni catalyst (Ni: 15 wt%) supported on precalcined SiO₂ has been investigated in reforming reactions of methane to synthesis gas. The catalyst exhibited fairly good activity and stability in partial oxidation of methane (POM), whereas it deactivated in steam reforming of methane (SRM). Pulse reaction results of CH₄, O₂, and CH₄/O₂ revealed that Ni/SiO₂ has high capability to dissociate methane. The results also revealed that both CH₄ and O₂ are activated on the surface of metallic Ni, and then surface carbon species react with adsorbed oxygen to produce CO and CO₂ depending on the bond strength of the oxygen species on the catalyst surface.
