(514e) Catalytic Conversion of NAS-CO2 to Chemical Feedstock

RTI’s current generation non-aqueous amine solvent (NAS) technology uses steam to strip CO₂ off the CO₂-rich solvent, followed by an activated carbon bed to capture the amine. As the capture side of the technology is currently undergoing commercial maturation, RTI has started to expand its research efforts in the utilization of the captured CO₂ to important chemical feedstock. Such conversion route will alleviate the cost associated with the energy intensive amine regeneration step as well as establish novel pathways towards carbon utilization. The work presented here will summarize the results of homogeneous and heterogeneous catalytic hydrogenation of CO₂, captured as carbamate to various feedstock. The effect of solvent, temperature and metal/ligand identity on the product selectivity and conversion efficiency will be discussed. This work presented here will showcase RTI’s capability of utilizing the CO₂ captured within the novel non aqueous solvent to further bring down the cost of the existing capture technology.
