The article presents a study of using foam glass as oil sorbents. The main object of these studies was glassy foams of inorganic (glass) and organic nature. The foam glass of the Gomelsteklo PLC was chosen for the experiment, which is due to the use of coal as a gas generator in its production. The oil used was REBCO (Russian Export Blend Crude Oil). Diesel fuel ULSD 10ppm (Ultra Low Sulfur Diesel) with a sulfur content of 10 mg/kg was used as a petroleum product. The obtained experimental results have allowed formulating the necessary as well as the necessary and sufficient conditions for the existence of peaks on the absorption kinetic curves for these sorbents in the initial period and identifying the factors that determine the height of the mentioned peaks and the maximum capacity of sorbents to oil and oil products (diesel fuel).
