While the anaerobic digestion is a relatively mature technology, the upgrading of bio-gas (i.e. removal of CO2 to yield pure methane) still needs to be optimized. Currently, the most widespread technology for CO2 removal is treatment with aqueous amine solutions. However, implementing this technology at small biogas plants can be problematic, because it is not modular. Using Ionic liquids which can reversibly bind CO2 is an alternative way to upgrade bio-gas. However, these liquids are very viscous which makes the gas-uptake extremely slow.  By forming a thin film of ionic liquids onto inorganic support materials like alumina and silica can remove the problem of slow gas-uptake. The resulting materials are also called “Supported Ionic Liquds” (SILP). In order to integrate the SILP materials into gas filters, it is necessary to shape them into monolithic form. Our group has made some progress in this field.  References: [1]: The GreenGasGrids Project: Boosting the European biomethane market Sustain DTU Abstract: E-31
