Insights into the CO Formation Mechanism during Steam Reforming of Dimethyl Ether over NiO/Cu-Based Catalyst

Abstract: Steam reforming of dimethyl ether on Cu-based catalyst was experimentally studied. It is found that formation of H2 and CO2 occurred over Cu/γ-Al2O3/Al, while methanol decomposition to CO and H2 was the main reaction over Cu/Ni/γ-Al2O3/Al in methanol steam reforming (MSR), which is similar to that on metallic Ni. However, XPS results show that nickel species existed as an oxidation state (NiO) over Cu/Ni/γ-Al2O3/Al. Therefore, reaction pathways of MSR over Cu(111) and NiO/Cu(111) were further explored using th… Show more

“…Many studies have focused on the steam reforming of hydrocarbon feedstocks over fixed-bed reactor using Ni-, Co-, Ru-, and Pd-based catalysts due to their strong capacity for breaking the C–C bond. Among these catalysts, Ni-based catalysts are more efficient and have a relatively lower cost of conversions of hydrocarbon feedstocks and selectivity of hydrogen. Nevertheless, Ni-based catalysts have a obvious tendency for activity deactivation in the process of reforming reactions as a result of coke formation, and the catalysts dosages used in the fixed-bed reactor is redundant. Therefore, how to improve the anti-coking ability and optimize catalysts utilization efficiency has become a research hotspot. …”
