Preliminary Assessment of Sorption Capacity on Solid CO2-Sorbents at Conditions for Sorption-Enhanced Processes
This work aims to assess solid sorbent capacity to operate CO2 capture under industrial conditions relevant to biogas/bio-syngas upgrading systems to green H2 and food-grade CO2 through Sorption-Enhanced Water Gas Shift (SEWGS) technologies.

| description | This work aims to assess solid sorbent capacity to operate CO2 capture under industrial conditions relevant to biogas/bio-syngas upgrading systems to green H2 and food-grade CO2 through Sorption-Enhanced Water Gas Shift (SEWGS) technologies. The pursued degree of innovation is the process intensification to remove CO2 in a more sustainable industrial practice reducing the CO2 footprint of a potential H2 production process.
A lab-scale apparatus is appropriately designed and built to operate at relevant industrial scale conditions. The core of the system is a fixed-bed reactor equipped with mass flow meters/controllers and online gas analyzers. CO2 capture experiments were carried out to investigate the effect of pressure (1.0-1.4 MPa) on different commercial and synthesized solid sorbent materials (hydrotalcite-like compounds). The best sorbent is a commercial hydrotalcite impregnated with 20 wt% of K2CO3, with an average sorption capacity of 0.85 mmolCO2/gad at 1.4 MPa and 623 K. The explored conditions are compatible with an industrial operation where syngas is available at low-to-moderate pressure. |
