High Temperature Separation of Carbon Dioxide/Hydrogen Mixtures Using Facilitated Supported Ionic Liquid Membranes
- Univ. of Notre Dame, Notre Dame, IN
Efficiently separating CO2 from H2 is one of the key steps in the environmentally responsible uses of fossil fuel for energy production. A wide variety of resources, including petroleum coke, coal, and even biomass, can be gasified to produce syngas (a mixture of COand H2). This gas stream can be further reacted with water to produce CO2 and more H2. Once separated, the CO2 can be stored in a variety of geological formations or sequestered by other means. The H2 can be combusted to operate a turbine, producing electricity, or used to power hydrogen fuel cells. In both cases, onlywater is produced as waste. An amine functionalized ionic liquid encapsulated in a supported ionic liquid membrane (SILM) can separate CO2 from H2 with a higher permeability and selectivity than any known membrane system. This separation is accomplished at elevated temperatures using facilitated transport supported ionic liquid membranes.
