Numerical and Experimental Investigation of an Adsorption-Based Purification of Biomass-Derived Syngas for Hydrogen Production
Short Introductive summary
Hydrogen, known for its high calorific value (140.4 MJ/kg) and potential for localized, large-scale production, is increasingly being explored as a key energy carrier in global efforts to mitigate climate change and limit the temperature rise to 1.5 °C. In this study, the adsorption behavior of a multi-component syngas mixture, representative of the typical output from an oxy-steam biomass gasification process, is experimentally investigated using zeolite 13X. The research focuses on fixed-bed adsorption columns packed with adsorbent, examining the competitive adsorption behaviour among CO_2, CO, CH_4, and H_2. Temperature profiles showed peak temperatures between 117 ? and 120 ?, consistent with strong exothermic adsorption activity. Using a custom-built fixed-bed setup with fresh Zeolite 13X, the system achieved ˜99% hydrogen purity for 3 minutes and maintained purity above 95% for 6 minutes. The sequential breakthrough of impurities (CH_4 at 11 minute, CO at 13 minute, CO2 at 46 minute) was observed through a series of in-house experiments. The methodologies and insights developed offer a valuable foundation for hydrogen production using adsorption-based separation system.
