Methane is a colourless and odourless gas that is the main component of natural gas and biogas. In exhaust gas cleaning it poses a particular challenge, as it is a chemically very stable molecule with a high bond energy. Breaking down methane catalytically requires significantly higher temperatures than ordinary VOCs, usually in the range of 400 \u00b0C to 450 \u00b0C. Methane is also a highly potent greenhouse gas (approx. 25 times more harmful to the climate than CO2), which is why reducing so-called “methane slip” in combustion engines is becoming increasingly important. Successful catalytic abatement of methane requires specialised catalysts with a high precious metal loading and optimised heat exchanger concepts in order to make the process economical. Because of the high temperatures required, autothermal operation is more difficult to achieve with methane than with highly volatile solvents. In industrial practice, mastering methane oxidation is regarded as proof of the highest technical expertise in catalyst technology, as the limits of the system’s thermal stability and of catalytic activity lie close together.<\/p>\n","protected":false},"excerpt":{"rendered":"
