Bi-reforming of Biogas for Hydrogen Production with Sulfur-Resistant Multimetallic Catalyst Poggio-Fraccari, Eduardo Mariño, Fernando Herrera-Delgado, María Concepción Larrubia-Vargas, María Ángeles Alemany-Arrebola, Luis José Biogas Hidrógeno -- Industria A multimetallic sample, NiCeSnRh/Al2O3, was tested in methane reforming with a CH4:H2O:CO2 molar ratio equal to 3:2:1. A very stable methane conversion with the time-on-stream was achieved during 20 h. Dimethyl sulfide served as a model sulfur molecule and a sulfurized sample was also tested. This achieved slightly lower conversion with a stable performance for more than 10 h and a minor but continuous decrease of its activity, after this period. The carbon dioxide conversion was always higher than the methane conversion in agreement with the lower H2/CO ratio observed with respect to the theoretical value, 2/1, indicating the sulfur might block the active sites for H2O activation. The analysis of the used catalysts showed graphitic and disordered carbon deposits 2023-05-05T11:37:49Z 2023-05-05T11:37:49Z 2023 journal article Poggio-Fraccari, Mariño, F., Herrera, C., Larrubia-Vargas, M.
