Study on the Manufacture of Activated Carbon from the Carbon in Coal Ash from a Power Station

WuXinhua and Yu Wei(Fujian College of Forestry,Nanping 353001)  
production process of activated carbon in which the carbon in a coal ash from a power station wasused as a starting material has been developed.Theoptimized conditions for this process to produce agranular activated carbon were using charcoal, whitecharcoal or coal as an auxiliary raw material,together with which the starting material wasundergoing a treatment in a preactivation process,then was washed with acid and water,and finallywas activated or even further reactivated ifrequired.The activated carbon product thus producedhad an iodine value of 600-700 mg/ g.Theactivated carbon from a pilot industrial production had an iodine value of 630-800mg/g with awearability of over 95%.This process provides anew way for coal ash to be utilizedcomprehensively.
