Energy saving

Cleaner methane with nanotechnology

The new catalyst will make methane even less polluting

Boilers methane, stoves catalytic, engines of cars e turbines gas to generate high performance and very low pollution current. These are just some of the applications that will be possible thanks to the recent discovery of a new process capable of making it 30 times more efficient combustion of methane.

The news circulated in August and comes fromUniversity of Trieste, which has been working on the project for some time in collaboration with the Universities of Pennsylvania and of Cadiz. The importance of the discovery depends on the fact that methane, the consumption of which is rapidly increasing worldwide, has a significant impact on pollution, albeit less than oil, and contributes togreenhouse effect.

At the base of everything there is a new one catalyst - that is to say a combustion facilitator - capable of reducing the temperature at which methane burns to release energy from 600 ° C to 400 ° C. Thinking for example of the car engine, to one gas boiler or at methane turbines, the catalyst allows to reduce the emission of unhealthy gases such as nitrogen oxides that are generated at higher temperatures due to the reaction between oxygen and nitrogen in the air.

The new process arises from nanotechnologies and by techniques known in the chemistry of materials, never however used before in this field, which enable a more economical use of palladium and cerium, metals used for the construction of catalysts. The result translates into energy saving, safety improvement of the industrial process and one reduction of the environmental impact.

FromUniversity of Trieste, leader of the discovery, they made it known that they already have contacts with some Italian companies for the technology transfer of catalysts and commercial use in new applications. The signing of a contract with an Italian company that produces should be announced shortly burners for natural gas boilers.
