复合添加剂对二氧化碳水合物生成条件影响的实验研究及动力学模型建立
Experimental study of effects of compound additives on CO2 hydrate formation conditions and kinetic model establishment
摘要
Abstract
CO2 sequestration and storage based on hydrate has a good prospect of industrial application. The effects of additives on CO2 hydrate formation were studied through the experiments with the aqueous solutions containing sodium dodecyl sulfate (SDS),sodium dodecyl benzene sulphonate (SDBS) or their mixtures as experimental solutions. It was found that the solution containing both of SDS and SDBS (SDS/SDBS mass ratio=1:1) at the concentration of 265 mg/L made the phase equilibrium point of CO2 hydrate fall to minimum and the formation of CO2 hydrate easier. This solution system could promote CO2 hydrate formation better than those solutions containing only SDS or SDBS. And a new kinetic model of CO2 hydrate formation, which had considered the compound effect of additives, was established.关键词
