Production of Activated Carbon from Waste PET’ Chars

Activated carbon, which is used in many application areas such as gas purification, purification of pollution water and wastewater, removal odor pollution, the defense industry, production protective clothing health sector, was produced from solid products obtained by waste polyethylene terephthalate (wPET) liquefaction that carried out under non-catalytic conditions, reaction time 15-90 min, a temperature 325-425 °C batch reactor. The obtained, after grinding, were made muffle furnace at 400-700°C nitrogen atmosphere for 30 min. contain approximately 60% Carbon (C), 4% Hydrogen (H) 36% Oxygen (O), are composed terephthalic acid (C8H6O4) crystalline form. According to Brunauer–Emmett–Teller (BET) analysis, BET surface area 313.05 m2g-1 average pore diameter 2.71 nm ZnCl2 activated carbons obtained. They have formed largely mesoporous structures. Scanning Electron Microscopy (SEM) it observed medium large porous structures formed. Produced commercial product potential but there need optimize process parameters better results.
