Abstract

PROCESSO PARA PREPARAR UM CATALISADOR DE REDUÇÃO CATALÍTICA SELETIVA. A presente divulgação fornece um método para preparar um catalisador de redução catalítica seletiva (SCR), o catalisador SCR compreende um zeólito com troca de íons de metal. Um método usa um processo de troca de íon in-situ. Um processo inclui a mistura por adição de um zeólito na forma de amônio (NH4+) com uma mistura aquosa compreendendo água, uma fonte de íon de metal de transição e, opcionalmente, um ácido, para formar uma pasta contendo um zeólito com troca de íons de metal.
