Reaction-Driven Ion Transport Membranes
Project No.: DE-FC26-98FT40343-CDP
Air Products and Chemicals is evaluating the applicability of Reaction-Driven Ion Transport Membranes (ITMs) in gasification facilities that process solid feedstocks, such as coal, biomass, petroleum coke, heavy hydrocarbon liquids, and other waste materials. Reaction-driven ITMs are a special class of ceramic oxygen (O2) ITMs. The driving force for oxygen separation is the chemical potential by reacting the permeated oxygen with a fuel at the permeate side. Two key areas of consideration include integrating the membranes with gasification and pyrolysis systems, and producing nitrogen (N2) for the gasification facility when ITM Oxygen technology is used to supply the O2 feed to the gasifier system. Capital cost, operating cost, and carbon dioxide (CO2) footprint reductions are the key potential benefits. The congressionally-directed project is identifying promising integration schemes of Reaction-Driven ITMs with gasifier and pyrolysis systems that have potential economic and CO2 footprint benefits. They are identifying the most cost-effective method of producing N2 in a gasification facility, determining operating performance, material stability, mechanical properties, and reliability of Reaction-Driven ITMs, developing novel Reaction-Driven ITMs, and developing equipment concepts to enable the use of the Reaction-Driven ITMs in high-temperature gasification/pyrolysis reaction systems.
