An improved, catalyzed process for the removal of CO2 from gas mixtures is described using a solution containing 15-40% by weight of potassium carbonate in which the absorption efficiency is enhanced by the addition of sodium or potassium vanadate equivalent to 2 to 10% by weight of V2O5 and sodium or potassium borate equivalent to 1 to 10% by weight of KBO2 in which the weight ratio of equivalent KBO2 to equivalent V2O5 is less than 1.5:1. It has been found that use of the described catalysts permits significant reductions in solution circulation rates (up to 45%), which leads to equipment and utility economies.
