Abstract

"APERFEIçOAMENTO DE PROCESSO DE PRODUçãO DE PARTìCULAS INORGáNICAS PARA SELETIVAMENTE REMOVER CONTAMINANTES DE FLUìDOS". é proposto processo de produção de um meio inorgânico, particulado, regenerável, capaz de remover contaminantes por oxidação catalítica ou redução, como também, metais pesados por absorção, de águas superficiais, subterrâneas ou servidos, o material específico sendo constituído de um compósito de partículas inorgânicas porosas, nas quais, sobre a superfície é depositada uma camada de bióxido de manganês fase gama ou epsilon, a deposição do bióxido de manganês sendo efetuada a partir de uma solução de nitrato de manganês, pelo recobrimento das partículas suportes com essa solução, secagem e tratamento térmico de decomposição do nitrato de manganês em NO~ x~ e <sym> MnO~ 2~, e o tratamento térmico sendo realizado em atmosfera controlada, contendo oxigênio e vapor de água, em temperaturas de 120<198>C a 400<198>C, e o material tratado termicamente sendo lavado até completa neutralização e lavada com água para remover finos e produtos da neutralização, sendo que certos gostos, odores e contaminações, como sulfeto de hidrogênio, ferro, arsênico e manganês podem ser oxidados e filtrados pelo meio e removidos do sistema por simples retro lavagem com água ou água em combinação com produtos químicos simples, e os metais pesados sendo removidos por um processo de absorção diferenciado e podendo ser retirados do meio filtrante com ácidos diluídos, esse produto demonstrando uma grande seletividade e uma alta capacidade, podendo ser produzido em diferentes granulometrias, porosidades, e densidades, podendo ser produzido sob medida para diferentes solicitações de projeto de separadores.
