摘要
Abstract
To enhance CO2 solubility in solvent and reduce the costs of solvent, a certain amount of aqueous ammonia and cosolvent were added into dimethyl carbonate (DMC) to form quasi-homogeneous mixed C02absorbent.The pedormance of mixed solvents ( DMC + mass fraction 10% aqueous ammonia + diethylene glycol monoethyl ether) was tested by the constant volume method under the different conditions, such as kinds of cosolvent, ratio of diethylene glycol ether, mass fraction of aqueous ammonia, aqueous ammonia ratio and temperature.The results show that the solubility of CO2 in DMC mixed with the other solvent increases with rise of ammonia mass fraction.Under normal pressure, the solubility of CO2 in the mixed solvents of V(DMC) : V ( 10%aqueous anunonia) : V (diethylene glycol monoethyl ether) =70: 15: 15 is 3 times higher than that in DMC.关键词
