Ecological aspects of study of carbon adsorbents and their characteristics depending on rice husk processing conditions

The industrial production and use of adsorption materials, especially carbon adsorbents, is steadily increasing every year worldwide. Natural coals plant waste are used to produce activated carbon. One the promising raw materials in Republic Uzbekistan for rice husk, because its renewability cheapness. paper highlights results study processing husks separate main substances - Pre-carbonization PW at 600°C with subsequent impregnation KOH solution further thermal activation 1000°C found increase specific surface coal 1286 m 2 /g, whereas sample obtained by carbonizate. 1108 /g after a solution. In all temperature ranges surface, characteristic greater first sample. Therefore, should be processed sequence: carbonization 600°C, 20% solutions 120°C within hours, water vapor temperatures above 850°C, which ensures higher characteristics produced.
