Abstract CO2 gas is responsible for greenhouse effect.Putting CO2 into seabed with the hydrate method can reduce CO2 gas and greenhouse effect,and not pollute environment.Consequently,the generation characteristics and physical property of CO2 hydrate,how to reduce its phase equilibrium point and accelerate formation rate are investigated.Based on experiments,the effects of the concentrations of additives SDS,SDBS,SDS-SDBS complex on CO2 hydrate phase equilibrium point were analyzed.The experimental results show that CO2 hydrate phase equilibrium point varies with temperature,the type and concentration of additives.Even in the same type,the optimum concentration also varies with temperature.The generation characteristics of CO2 hydrate had been analyzed simply and summarized.
