摘要: Two processes to produce hydrogen via steam reforming are compared in a laboratory fixed bed reactor: conventional with nickel-based catalyst and sorbent-enhanced mixture of CaO−Ca12Al14O33 sorbent. A preliminary thermodynamic study was performed determine the operating window sorption enhanced at atmospheric pressure. Operating temperatures less than 650 °C required take advantage favorable thermodynamics due situ capture CO2, while maximum gain methane conversion between two process options is attained for molar ratio around 3. Under these conditions, (85:15 wt) synthesized using calcium acetate as CaO precursor acted an effective CO2 sorbent, reducing by 67% amount total that would have been emitted reforming. Due capture, equilibrium shifted higher purities. H...
