METHOD OF PREPARING GRANULATED ACTIVE CARBON FROM PEAT Russian patent published in 2001 - IPC

FIELD: purification of exit gases and sewage. SUBSTANCE: method comprises mixing original feedstock, such as peat with activator and binder, granulating mixture, carbonization and vapor gas activation. Peat activator and binder include industrial lignosulfonate dried to air-dry state. Mixing is carried out with water to moisture content of 50-56 wt % and peat to lignosulfonate ratio of 2-2,2:1, carbonization is carried out 950-600 C, and activation is carried out at temperatures from 260 to 800 C for 60-80 minutes, claimed method saves energy resources, is ecologically cleaner and makes it possible to prepare carbon having good sorption and mechanical characteristics. EFFECT: more efficient preparation method. 3 ex, 1 tbl
