Biomass wastes for water treatment by adsorption with activated carbons

摘要：

Activated carbons (AC) are prepared from agricultural wastes (cob corn and bean pods) and a mixture of coal tar pitch and furfural by pyrolysis (synthetic carbon). The pyrolysis of agricultural wastes is carried out at 600℃. The activated carbon from coal tar pitch and furfural is obtained after treatment with H2SO4 and subsequent activation with water vapor at 800℃. The BET surface area of these activated carbons is 500 m2/g for activated carbon obtained from cob-corn, 258 m2/g for activated carbon obtained from bean pods and 678 m2/g for synthetic carbon. The produced activated carbons are used for removal of phenol. The most active in the adsorption process is the activated carbon from cob-corn where the adsorption capacity is 131 mg/g, while this value for bean pods activated carbon is 85 mg/g and 101 mg/g for synthetic carbon.
