Investigation of the Process Carbon Dioxide Hydrate Formation in a Colloidal Solution Containing Al2o3 Nanoparticles and Sodium Dodecyl Sulfate

This paper presents the results of an experimental study on the formation of carbon dioxide hydrate in a colloidal aqueous solution of aluminum oxide (Al2O3) and the anionic surfactant sodium dodecyl sulfate (SDS), which acts simultaneously as a kinetic promoter of hydrate formation and a stabilizing agent for the colloidal solution. Oxide nanoparticles were selected for the study due to their high specific surface area, which potentially facilitates the nucleation of gas hydrate. The presence of a large number of aluminum oxide particles increases the number of nucleation sites during crystallization. Additionally, these particles may participate in the process of gas transfer from the liquid-gas interface to the bulk liquid. The dependencies of the released energy and the conversion of the solution and carbon dioxide into the gas hydrate state were obtained.
