Project Description

This TDA project will demonstrate the technical and economic viability of an integrated water-gas-shift (WGS) catalyst/CO2 removal/thermal management system for an IGCC power plant and a coal to liquids (CTL) plant. It will explore the best reactor design option that allows for the integration of a proven high temperature CO2 adsorbent and a commercial WGS catalyst with improved thermal management. It will also use CFD modeling to assess the potential of using filter tubes for direct evaporative cooling while simultaneously supplying the process with the reactant steam. New reactors will be fabricated to evaluate the performance of the integrated system, first in the bench-scale tests and then in a field demonstration using actual coal-derived synthesis gas.

Project Benefits

TDA Research, Inc. will develop a new high-hydrogen synthesis gas production technology and demonstrate its techno-economic viability for use in integrated gasification combined cycle (IGCC) power plants and coal-to-chemical plants (production of methanol, a precursor for gasoline production) that process low-rank coals and woody biomass. Specifically, the new system will use a warm gas CO2 scrubber integrated with a water-gas shift catalyst to capture greater than 90% of carbon emissions. With expected net plant efficiency 3-5% higher than plants using Selexol for CO2 capture, the technology would significantly reduce the cost of carbon capture over the current state-of-the art, reduce carbon emissions, and have favorable impact on cost of production of electricity and value-added products from coal-based gasification systems.
