Abstract
The invention relates to a continuous method for producing formic acid from CO2 and extracting the formic acid using compressed CO2.
Claims10
A method for hydrogenation of CO2 to formic acid, comprising the following steps:
- a) producing formic acid by a catalytic reaction of CO2 with hydrogen in the presence of a base, in a reaction area;
- b) at least partially discharging the produced formic acid using compressed CO2 from the reaction area of step (a);
- c) releasing the formic acid while removing the CO2 from step (b).
