N2 - In contrast to gas hydrate with pure water, the presence of salt in the solution inhibited the synthesis of SF6 hydrate. The dissociation of an SF6 hydrate layer with SiO2 nanoparticles at atmospheric pressure was investigated experimentally. During the dissociation process, there were aggregated SiO2 particles both inside the layer and on its surface. The SiO2 particles caused more intense ice melting and water formation. During the ice melting and water film formation, the SiO2 particles partially clogged pores in the sample layer and reduced the porosity of the layer, which prevented the gas from leaving the hydrate. In contrast to pure gas hydrate, the dissociation of hydrate with SiO2 particles is accompanied by the formation of large gas bubbles on the surface of the powder layer. The presence of SiO2 particles leads to an increase in the total dissociation time of SF6 hydrate by 23–30%.
