A.G.Gadalla, Joseph Y.Farah, S.S.Mohamed, N.N.Ibiari

Rice husk, as an agricultural waste, was utilized in production of high quality activated carbon by alkali chemical activation method. The process takes place through three steps, carbonization, activation and washing. Different operating parameters in each stage have been studied. The high quality activated carbons produced at optimum operating conditions have surface areas of 2470, 2980 m2/g and methylene blue values of 750, 940 mg/g for KOH and NaOH respectively.
