Raman study of the sulfur poisoning of multimetallic catalysts for the self-reforming of biogas. Peltzer, Diana Poggio-Fraccari, Eduardo Molina-Ramírez, Sergio Cortés-Reyes, Marina Herrera-Delgado, María Concepción Larrubia-Vargas, María Ángeles Alemany-Arrebola, Luis José Productos químicos de la biomasa Catalizadores Biogas reforming is an eco-friendly alternative for syngas or hydrogen production, as it generates low, or even negative, carbon emissions. If a proper amount of steam is added to the untreated biogas, a steam compensated self-reforming (CO2 + H2O) may be implemented1 . However, the presence of sulphur species in raw biogas could promote the catalyst poisoning. In this sense, commercial Ni-based catalysts may be deactivated with sulphur concentrations as low as ppb. One alternative is the employment of sulphur tolerant catalysts. Therefore, the mail goal of this contribution is to study the effect of sulphur poisoning on the structure of a multimetalic non-supported catalyst for the self-reforming of biogas. The studied catalysts are based on Ni and Ce, adding Rh and Sn as promoters for the reforming activity, coke resistance, and sulphur tolerance. 2025-10-24T11:11:45Z 2025-10-24T11:11:45Z 2024-07-14 conference output https://hdl.handle.net/10630/40450 eng 18th International Congress on Catalysis (18th ICC) Lyon, France 14-19 julio 2024 open access
