Abstract

"PROCESSO PARA PREPARAçãO DE ZEóLITAS TIPO PENTASIL DOPADAS USANDO SEMENTES DE FAUJASITA DOPADA". A presente invenção refere-se a um processo para preparação de zeólita tipo pentasil dopada, processo esse que compreende as etapas de: a) preparar uma mistura aquosa precursora compreendendo uma fonte de silício, uma fonte de alumínio, sementes de faujasita dopadas e outro tipo de material de semeadura, e b) tratar termicamente a mistura precursora para formar uma zeólita tipo pentasil dopada. Este processo resulta em zeólitas tipo pentasil dopadas em um tempo de cristalização menor comparado com o de processos da técnica anterior.
