Dry reforming of methane over CeO2 supported Ni, Co and Ni–Co catalysts

“…Economics of syngas manufacture depends strongly on the price and availability of the raw material, methane in most situations, which generally determines the economics of the downstream processes [4][5]. The most common processes to convert natural gas into synthesis gas can be listed as steam reforming of methane, partial oxidation of methane and carbon dioxide reforming of methane (or dry reforming of methane) [6]. Carbon dioxide reforming of methane becomes industrially advantageous compared to partial oxidation and steam reforming in synthesis gas production due to the fact that the H 2 /CO product ratio in dry reforming is close to one, which is appropriate for further use in the production of oxygenated compounds as well as Fischer Tropsch synthesis for liquid hydrocarbons production [7].…”

Mesoporous zirconia-modified clays supported nickel catalysts for CO and CO 2 methanation

“…This result is in accordance with that measured by the EDX. The mass loss of 0.010 mg from 606 C to 655 C is ascribed to the active carbon deposited on the surface of the catalyst [56,57], accounting for 0.12% of the total mass of the dry catalyst. The active carbon is responsible for the formation of methane.…”

“…9b shows the TG profile of the catalyst after 40 h on stream for CO 2 methanation. The mass loss at the temperature below 163 C is ascribed to the moisture evaporation [56,57], and the mass gain at the temperature range from 163 C to 592 C is ascribed to the oxidation of the metallic nickel species in the catalyst. The mass gain of 0.411 mg is the mass of oxygen in NiO.…”

“…Therefore the mass of NiO in the catalyst is 1.918 mg, which accounts for 23.81% of the total mass of the dry catalyst. The mass loss of 0.010 mg from 592 C to 651 C is ascribed to the active carbon deposited on the surface of the catalyst [56,57], which accounts for 0.12% of the total mass of the dry catalyst. The TG analysis indicates that no inactive carbon deposited on the catalyst for both CO and CO 2 methanation.…”
