ADSORPTION OF PETROLEUM PRODUCTS BY HEAT-TREATED SAPROPEL OF LAKE LIPOVO, NOVGOROD REGION IN DYNAMIC CONDITIONS
The study of adsorption of water-soluble petroleum products from model solutions with a concentration of 10 mg/dm3 heat-treated at 600°C sapropel lake Lipovo Novgorod region under dynamic conditions (the height of the sorbent layer 7, 9, 14 cm; linear velocity 4 cm/min). The values of DEС and FDEC for heat-treated sapropel at 600°C were determined. It is established that the process of adsorption of water-soluble petroleum products under dynamic conditions is mixed-diffusion. Using the Shilov equation for a mixed-diffusion adsorption model in the parallel transfer mode, kinetic constants of the adsorption dynamics of water-soluble petroleum products on heat-treated sapropel at 600°C are calculated.
