| 摘 要： | Under atmosphe()e press()ne, rates of deseption of CO() from unmod()ed carbonated potash solutior (27 wt%)and modified carbonated potash solution(27 wt%) containing DETA as a catalyst, have been measured in a laboratory stirred reactor. Experiments were carried out with concentrations of DETA from 0—40g/L and temperatures from 90—104℃The results, show that the desorption of CO_2 from hot carbonated solutions with and without the addition of DETA, may be considered a pseudo-first order reversible reaction, and that the desorption of CO_2 from carbonated potash solution calalysed by DEIA is in agreement with the mechanism of simultancous reactions of CO_2 with amine molecules and with hydroxyl ions in solution. Mathematical models for desorptions rate cocflicient have been cstablished, and optimum concentration of DETA is proposed.
