Carbon adsorbents from of shale oils and phenols

The liquid products of shale conversion—shale oil and shale phenols (a mixture of alkylresorcinols) and their solutions in commercial furfural, which are used as a new binding agent—make it possible to form carbon adsorbents with high mechanical strength (to 97%), microporosity (to 0.70 cm3/g), and higher sorption capacity than that of industrial adsorbents. The medium-combustion-loss samples exhibited higher selectivity in the extraction of noble metals from the multicomponent polymetallic solutions than those formed of traditional wood tar. They also outperform industrial adsorbents in these characteristics. It is possible to apply them to the absorption and concentration of aromatic hydrocarbons and to use them at atomic power plants, transport, and air conditioning plants for food and vegetable storage.
