文摘

Method for obtaining molded activated carbon on the basis of carbon black, petroleum pitch, and potassium hydroxide is suggested. The method consists in mixing of these components in the presence of a solvent, molding, and subsequent carbonization at temperatures of 600–1000°C, followed by washing. The resulting samples have a specific surface area of up to 700 m2 g–1, total pore volume of 0.6–1.5 cm3 g–1, and crushing strength of 1–4 MPa. This material can find industrial use in purification of technological gases and fluids in fixed-bed adsorbers.
