Abstract

METODO Y APARATO PARA EL TRATAMIENTO DE MATERIALES FIBROSOS CON UN REACTIVO GASEOSO, SIENDO LOS MATERIALES MULLIDOS DE ALTA CONSISTENCIA, DISPONIENDOSE DE UNA CAMARA MEZCLADORA MECANICA CON UN TIEMPO DE ESPERA SUFICIENTE PARA PERMITIR LA REACCION DE UNA MAYORIA SUSTANCIAL DEL REACTIVO GASEOSO, ANTES DE DISTRIBUIR LA MEZCLA DENTRO DE UNA CAMARA DE LECHO POROSO DE REACCION Y DESGASIFICACION. EL GAS FLUYE A TRAVES DEL LECHO POROSO DE MATERIAL FIBROSO EN LA CAMARA DE REACCION, HASTA QUE VIRTUALMENTE TODO EL REACTIVO ACTIVO HAYA SIDO CONSUMIDO. ESTO TIENE COMO RESULTADO MATERIALES FIBROSOS TRATADOS UNIFORMEMENTE Y UNA UTILIZACION EFICIENTE DEL REACTIVO.
