To date, there are at least several technologies for ” storing ” atmospheric CO2. However, researchers at the Massachusetts Institute of Technology (MIT) went further. They have learned how to convert the carbon dioxide released from fuel combustion to TPP into raw materials, which can then be processed into fuel for cars and aircraft, as well as into other substances.
Dr. Xiao Yoo Woo, together with Ahmed Guniem and engineering professor Ronald Crane, developed a membrane system based on the compounds of lanthanum, calcium and iron oxide, through which carbon dioxide (CO 2) is converted to monoxide-CO.
The separation process itself occurs at a temperature of 990 ° C. It is very important that the SB continue its “path” through the membrane until it is on the opposite side. This can be achieved with the help of vacuum, but this requires a lot of energy.
An alternative to costly technology can be the use of a stream of hydrogen or methane, since these substances are easily oxidized and do not require a pressure difference for “pumping” oxygen atoms through the membrane.
The resulting carbon monoxide can be used directly as a fuel, and in combination with hydrogen, water or a mixture thereof, to produce a liquid hydrocarbon fuel and other valuable chemical products, methanol, synthesis gas, etc.
