In this study, the effect of nanoparticle of graphene oxide and surfactant sodium dodecyl sulfate (sds) 400 ppm on the storage capacity of co2 in hydrate was investigated. A laboratory system was developed for hydrate formation experiments. The experiments were carried out in the range of pressure 36-40 bar, temperature range from 273.35 k to 278.65 k, in the presence of graphene oxide and sodium dodecyl sulfate. Experimental results showed that by increasing the pressure at constant temperature for net water, storage capacity increased by 11%, and the storage capacity increased by 14% by decreasing the temperature at the constant pressure (36 bar). Adding sds increased storage capacity by 26%, while adding graphene oxide increased 4.2% of storage capacity. For this purpose, design expert software and response surface test method and historical method were used. Also, a mathematical equation was proposed to estimate the co2 storage capacity in hydrate.
