چکیده انگلیسی
Non-metallic fractions of FR-3 type waste printed circuit boards were pyrolyzed at high temperatures. The resultant char at 600 °C was used to prepare activated carbons by physical and chemical activation. The influence of pyrolysis temperature on char yields, and activation conditions on the burn-off and porous properties of the activated carbons were investigated. Results show that char yields decrease with pyrolysis temperature. A granular activated carbon with a surface area of 1 019 m2·gâ1 and a pore volume of 1.1 cm3·gâ1 can be obtained by moulding, pyrolysis and physical activation using H2O as an activation agent. An activated carbon powder with a surface area of 3 112 m2·gâ1 and a pore volume of 1.13 cm3·gâ1 can be achieved by KOH activation.
