Steam Biomass Gasification with in Situ CO2 Capture for Advanced Syngas Applications

Short Introductive summary

This work deals with the production of a syngas with a high H2 content to be used for further application, such as hydrogen production. To this aim, a process based on steam biomass gasification coupled with in-situ CO2 capture is under development. The feedstocks considered cover a wide spectrum of types, ranging from residual biomass of different origins to the biogenic fraction of waste. Moreover, with the employment of HTC, feedstocks of low grade (i.e. high humidity, ash and inorganic elements content) are considered. The possibility of exploiting the greatest variety of low-value feedstocks is indeed a key aspect towards the development of a technology allowing to combin H2 production with a low carbon footprint with sustainability and profitability criteria. Using a 50 %-wt calcined dolomite/olivine bed inventory, a syngas with a H2 content above 50 %-v (H2/CO 3.5), a 40-75% reduction in tar (based on gravimetric data) and, depending on the feedstock considered, decreases in H2S and HCl levels to values of tens of ppm-v, or lower. Given the preliminary results, superior performances are expected by properly dosing the dolomite material in the mixed bed inventory.
