Abstract

PROCESSO DE REDUçãO DE METAIS PESADOS DOS GASES DE FUMAçAS. A presente invenção refere-se ao processo de redução de metais pesados, em particular de mercúrio, presentes nos gases de fumaças, compreendendo um estágio de colocação em contato com os gases de fumaças, com uma matéria sólida de sorção no estado seco, no qual a matéria sólida de sorção é um composto mineral não funcionalizado.
