Abstract

CATALISADOR DE DESNITRIFICAÇÃO E MÉTODO DE DESNITRIFICAÇÃO USANDO O CATALISADOR. Divulga uma zeólita do tipo FER tendo pelo menos silício, alumínio e oxigênio como átomos da estrutura principal, onde uma razão molar entre átomos de silício para átomos de alumínio é de 2-100:1. Além disso, quando a espectroscopia de ressonância magnética nuclear de 29Si sólido é usada para analisar a zeólita, uma área de pico na faixa de deslocamento químico de -90 ppm a -110 ppm é responsável por 25% ou mais de uma área de pico na faixa de deslocamento químico de -90 ppm a -125 ppm. Também são divulgados um método de preparação e uma aplicação da zeólita de FER.
