The paper presents a study of the formation of gas hydrate in a colloidal solution of water + SDS + SiO2. The effect of the kinetic promoter of sodium dodecyl sulfate (SDS) on the process of hydrate formation was studied at various concentrations: 0, 100, 300, 500 ppm at a constant SiO2 concentration of 500 ppm. A description of the experimental research methodology is given, the dependences of pressure and temperature changes on time for each SDS concentration are shown, and the coefficients of conversion of water and gas into the gas hydrate state are determined. The studies were carried out using carbon dioxide as a hydrate-forming gas.

The paper presents a experimental investigation of carbon dioxide hydrate formation in a colloidal solution of H2O+ SDS + SiO2 The influence of the kinetic promoter of sodium dodecyl sulfate (SDS) on the formation of carbon dioxide gas hydrate at various concentrations: 0, 100, 300, 500 ppm was assessed. The SiO2 concentration in the solution was constant and equal to 300 ppm. The change in solution temperature and pressure during the production of hydrate is shown for each SDS concentration. The values of convection of solution and gas into the gas hydrate state were determined.

In this work, arc discharge synthesis was carried out by sputtering electrodes of various compositions in a helium medium, as a result of which two types of materials containing carbon globules and graphene flakes were obtained. The synthesized materials were characterized with transmission electron microscopy, scanning electron microscopy, and Raman spectroscopy. The effect of the type and concentration of carbon nanoparticles and the type of surfactants on the stability of water-based nanofluids was studied with optical spectroscopy. For carbon globules and water, the mass concentrations of nanoparticles and sodium dodecyl sulfate were determined to obtain a nanofluid based on them stable for 1 month, which are 0.02% and 1%, respectively. It was shown that the use of neonol AF 9-12 at a concentration of 2% didn’t lead to the stabilization of carbon globules with a mass concentration of 0.02% in water. For graphene flakes, the mass concentrations of nanoparticles and stabilizers to obtain a water-based nanofluid stable for 1 month were: 0.02% graphene flakes and 1% SDS, as well as 0.02% graphene flakes and 2% neonol AF 9-12, respectively.
