Research of Mixed Carbon Sorbents for Removal of Oil Products from Water and Soil for Preservation of Environmental Infrastructure

Abstract The article presents the results of studies on the study of technologies for obtaining carbon sorbents from by-products of agriculture, woodworking industry and utilities under the influence of low-temperature one-stage carbonization, as well as structural, physicochemical, absorbing properties of mixed carbon-carbon and carbon-mineral sorbents and their effectiveness and economic feasibility in removing petroleum products from the environment and preserving its infrastructure. Oil consumption and absorption capacity of petroleum products of the mixture of pine sawdust carbonate: expanded graphite, at a ratio of 50:50%, 2.5-3.0 times higher than the sawdust carbonate. Its use is the most promising and cost-effective in removing petroleum products from the environment and preserving environmental infrastructure. The obtained data on influence of the qualitative composition of mixed materials on their sorption capacity in relation to oil and oil products allow us to suggest the feasibility of using carbon-carbon materials as effective sorbents of oil products from water and soil, and carbon-mineral, for example, as effective barriers to preventing the migration of oil and petroleum products into groundwater. Carbon-carbon materials should be used as effective sorbents to remove petroleum products from the water surface and soil, and carbon-mineral as effective barriers to prevent the migration of oil and petroleum products into groundwater.
