Zusammenfassung:Pore properties of activated carbon made from pruned apple branches on air-activation were investigated by comparison with the carbon from sugi (Cryptomeria japonica D.DON) prepared in the same way and commercial activated carbon. The results showed that the activated carbon ash prepared from pruned apple branches contained a lot of calcium, and its ash yield was highest. Besides we found that the external specific surface area and mesopores with the diameter 4-20nm range were the largest. It was supposed to be caused by catalytic action of calcium.
