Carbon adsorbents from petroleum pitch
Adsorbents with a developed micropore volume (up to 0.34 cm(3)/cm(3)) and high sorbing power for oxygen, carbon dioxide, and xenon can be obtained by an industrial scheme from stock containing petroleum pitch as binder or pitch copolycondensate as base. Medium combustion loss adsorbents are characterized by high sorption activity in absorption of arsenic from wastewaters. They can be used as recovery adsorbents for absorption and concentration of benzene and toluene and in nuclear power plants, transport, and units for regulating the composition of the air in product and vegetable warehouses.
