Evonik Industries says its plasma reactor operates at a temperature of just 30 °C.

Evonik Industries is working with three German partners on a project to turn carbon dioxide into chemicals. The partners, which are receiving about $2 million from the German government, intend to use low-temperature plasma as an energy source that converts CO2 into carbon monoxide, which in turn can be combined with hydrogen to produce C4-family chemicals such as isononanol and trimethylhexanal. Evonik hopes to open a pilot plant in about 4 years.
