FIELD: process engineering.
SUBSTANCE: invention relates to production of filtration elements for baromembrane processes used in various industrial branches: petrochemical, pharmaceutical, food, etc. Proposed method comprises deposition of carbon produced in pyrolysis of hydrocarbons on workpiece macro pore surface. Substrate preparation is performed by impregnating carbon or ceramic substrate by water solution of cobalt, nickel and magnesium nitrates with addition of citric acid and ethylene glycol. Then, prepared substrate is subjected to thermal treatment and, at temperature of propane-butane mix pyrolysis, carbon nonmaterial is deposited to production of carbon nanomaterial.
EFFECT: production of anisotropic membranes for ultra- and nanofiltration of gases, vapor-gas mixes and fluids.
