CO2 reforming of methane over Ni/Al2O3 catalysts: effects of catalyst composition, and water and oxygen addition to the feed

摘要

Catalytic dry reforming of methane with CO2 (DR) has received considerable attention in recent years, owing to the fact that it converts two greenhouse gases (CH4 and CO2) to valuables synthesis gas (syngas), a mixture of CO and H2 (1). The DR process becomes industrially advantageous compared to steam reforming (SR) or partial oxidation (POX) in syngas production since it yields H2/CO product ratio close to 1/1, which is suitable for further use in production of oxygenated compounds as well as Fischer-Tropsch synthesis for production of valuable hydrocarbons (2).
