Popis:	The properties of active carbons, products of the steam activation (400–900°C) of mixtures of washed-off petroleum waste and lignin, were studied. The dependences of the yield, the specific surface area, and adsorption activity with respect to iodine (A I) and methylene blue (A MB) on the activation temperature (400–900°C), as well as the characteristics of the pore systems and the parameters of active-carbon supermolecular structure, were obtained. As compared with the properties of active carbon from lignin, the activation of the mixture leads to the formation of active carbon with lower yields, a higher specific surface area, and a substantially (by a factor of 3) increased proportion of mesoporosity. The adsorption properties of active carbons from lignin and its mixture with washed-off petroleum waste are close (A I = 950−1000 mg/g and (A MB = 200−220 mg/g).
