Abstract
An energy integrated process is disclosed for the conversion of carbon dioxide to a liquid product. The conversion reaction is exothermic. The heat of reaction and the heat of condensation of the reaction product or products are used as energy input in a carbon dioxide enrichment step. The enrichment step produces a feed gas for the conversion reaction.
Claims14
An energy integrated CO2 conversion process comprising the steps of
- a. a CO2 enrichment step whereby the CO2 concentration of a feed gas is increased, said enrichment step requiring an energy input;
- b. a CO2 conversion step whereby CO2 is converted to a liquid product, said conversion step producing an energy output;
- whereby the energy output is used to at least partially offset the energy input,
- wherein the feed gas is ambient air, and wherein step a. is operated at a temperature in a range of from 250K to 450K,
- wherein step b. produces from 100 kJ to 200 kJ per mole of converted CO2.
