Abstract

"MéTODO DE PRODUçãO DE UM MEIO DE FILTRO". Uma abordagem para incorporar beneficamente tanto um impregnante orgânico sólido como um impregnante fluido em partículas de meio de filtro, sem que a presença ou adição de um desnecessariamente afete o desempenho do outro. A presente invenção efetua a impregnação através da combinação de técnicas de sublimação e de absorção não efetuada a granel. Estas técnicas podem ser executadas em um modo seq³encial, simultâneo, em sobreposição, e/ ou em alternância, ou os similares. A invenção é especialmente adequada quando as partículas de meio de filtro já contêm ou devem conter um ou mais outros impregnantes, cuja função ou presença pode ser adversamente afetada quando métodos convencionais são usados para adicionar materiais sólidos orgânicos e materiais fluidos.
