【Abstract】 The objective of this research was to scrutinize the catalytic efficacy of the SCST-201/202 catalyst in the primary reformer for methane steam reforming.A reaction kinetics-based model was developed and validated to assess the catalyst’s performance.The study delineates the intrinsic properties of the SCST-201/202 catalyst utilized in methane steam reforming,with particular emphasis on the pressure drop across the catalyst bed.The effects of diverse water-to-carbon ratios,inlet temperatures,and pressures on methane conversion rates,hydrogen yield,CO selectivity,and reactor pressure drop were systematically investigated.The results underscore the catalyst’s superior catalytic activity,minimal operational resistance,and robust resistance to carbon formation,indicating its suitability for industrial-scale methane steam reforming processes aimed at hydrogen production.更多还原
