Project Description

TDA Research, along with their partners Gas Technology Institute and University of California Irvine, are developing a novel sorbent-based, thermo-catalytic process to convert carbon dioxide (CO2) captured from coal-fired power plants into syngas (carbon monoxide [CO] and hydrogen), which can be used to synthesize synthetic fuels and value-added chemicals. The project will focus on the development and optimization of a mixed metal oxide sorbent to directly reduce CO2 to CO. Initial work will synthesize and screen sorbent formulations for the best CO2-reduction capability and test sorbent activity over multiple absorption / desorption cycles. The team will design and fabricate a prototype sorbent reactor and complete proof-of-concept testing, evaluating CO2 conversion to CO through varying conditions. Additional work includes development of a computational fluid dynamic model of the sorbent reactor system and validation of the model with bench-scale testing. The team will establish the basis for process design and develop Apsen Plus™ models that use the CO2 utilization system integrated with two chemical conversion processes; to diesel fuel via Fischer-Tropsch synthesis, and to gasoline via a methanol-to-gasoline process. A detailed design, a techno-economic analysis of the process, and a life cycle analysis, will also be completed.

Project Benefits

The process provides a pathway for the beneficial utilization of CO2 from coal-fired power plants to produce syngas, which can be used as a building block for synthesizing a wide range of materials such as synthetic fuels, alcohols, and other value added chemicals. The energy needed to operate the CO2 conversion process will come from renewable sources allowing the CO2 to be reduced without generating additional greenhouse gas emissions.
