Minimize emissions of carbon dioxide.

Minimize emissions of carbon dioxide.
An integrated process for producing energy from burning waste methane without carbon dioxide has been proposed by British scientists. With the weather change is a threat today, the reduction of CO2 emissions is essential. But the increasing energy demand means the solution is not as simple as cutting the burning of fossil fuels. Michael North and his team at Newcastle University says that it is possible to maintain energy production and as soon as possible to change the CO2 waste into useful chemicals that prevent the financing associated with carbon capture and storage.

North system uses a membrane to separate and provide pure oxygen in the fuel that provides a clean burning, by eliminating a NOx production. Then, given the CO2 waste into a reaction mixture with a is then fed into a reaction mixture with an epoxide and a catalyst that produces carbonate - carbonate. Cyclic carbonate has many applications - applications including degreasing agent, and solvent elektrolite.

Although the reuse of waste CO2 is to create a cyclic carbonate is not a new idea, previous proposals include the use of a catalyst that requires a temperature above | 150 ° C and high pressures that require more energy to be included. North previously had developed an aluminum complex with kokatalis Tetrabutylammonium bromide as a reaction to mengkatalisasikan temperature range 20-100 ° C, in accordance with the waste heat from power generation.

A catalyst Tetrabutylammonium allow conversion of carbon dioxide under mild conditions.
'Elegance of this systematic is you are not making a CH or CC bond of the new, so the reaction is exothermic,' said North.

Nilay Shah, an expert in chemical engineer at Imperial College London, England, was impressed by this system. 'This is about the creativity to find the best molecules to make the CO2, so you can start to create a molecule with a high volume of real,' he said.

North shows this process in laboratory scale but said that he was confident this can be made into the process of continuous flow to commercial systems. He also plans to further research on the catalyst tolerance to water and other impurities.
