Combining CO2 capture and catalytic conversion to methane

Considering the global objective to mitigate climate change, import efforts are made on decreasing the net emission of CO2 from gas effluents. On the one hand CO2 capture—for example by adsorption onto solid basic materials—allows to withdraw CO2 from the waste gas streams emitted by incinerators, cement manufacture plants, combustion plants, power plants, etc. On the second hand, CO2 can be converted to useful chemicals—e.g. hydrogenation to methane—using appropriate heterogeneous catalysts. A relatively innovative strategy consists in combining both technologies by designing material... Mehr ...
