Abstract:Low-ash activated carbon is produced with phosphoric acid as the activating agent ,and the operation conditions are discussed in some detail. The effects of the concentration of phosphoric acid ,activating temperature on the content of ash in activated carbon are experimently examined ,and optimum condition's have been found. The optimum conditions are those with altivoting temperature at 350 ℃ and the mass froution of phosphoric anid that dipped in the chip being 68.9%.
Keywords:phosphoric acid  low ash  activated carbon
