CARBON ADSORBENTS FROM PETROLEUM RESIDUES

Data are presented on utilizing petroleum asphaltite as an addition to the charge and a binder when obtaining adsorbents as well as the products of their thermal and chemical modification. High effective microporous adsorbents have been produced whose sorption indices are higher than industrial ones. They may be used as carriers of hemosorbents, clarifying carbons, and for selective isolation of the noble metals from multicomponent solutions. The new adsorbents may be useful for air purification in rooms, for keeping the required temperature in food storage, as well as for cleaning nuclear power plant gas effluents.
