METHOD AND PLANT FOR PRODUCING DECOMPOSITION PRODUCTS USING WATER AT SUBCRITICAL PARAMETRES Russian patent published in 2010 - IPC B01J3/00 B09B3/00 C08J11/14 

FIELD: process engineering.

SUBSTANCE: invention relates to processing of material containing solid substance by decomposition using water at subcritical parametres. Proposed method comprises feeding initial stock into reactor with its inner volume maintained at subcritical water parametres via reactor inlet pipe. Stationary layer, fluidised layer and layer of fluid containing decomposition product in water with subcritical parametres are created inside reactor. Withdrawal of fluid containing decomposition product in water with subcritical parametres is performed via any of multiple discharge pipes arranged at different distance from reactor inlet pipe that allows creating stationary flow of said fluid and regulating period of its presence inside reactor. Withdrawal of target decomposition product is performed via any discharge pipe selected from multiple outlet pipes located at the level with high concentration of target decomposition product.

EFFECT: regulation of decomposition reaction, reduced costs and selective production of target substances.
