Fraunhofer-Gesellschaft have developed a technology for the energy-efficient and economic separation of hydrogen from natural gas.
...an ultrathin layer on porous, ceramic substrates where it acts as a membrane, separating natural gas and hydrogen from one another. There are various processes involved in membrane production, starting with custom polymer synthesis. Polymers are substances consisting of branched macromolecules. These are then applied to the porous substrate. When the polymer is heated up and starved of oxygen at the same time, it forms a layer of carbon on its surface. The pores in the carbon are less than a nanometer in diameter, and this makes them effective for gas separation. Physical and chemical processes can be employed to adapt the membrane’s separation behavior even further. Fraunhofer IKTS has been collaborating with Leipzig-based DBI Gas- und Umwelttechnik GmbH to develop tubular carbon membranes.
