Abstract

"PROCESSO PARA A PREPARAçãO DE ZEóLITO CRISTALINO Y". Descreve-se um processo para a preparação de zeólito cristalino de aluminossilicato Y a partir de uma mistura de reação contendo apenas suficiente água para produzir o zeólito Y. Em uma concretização, a mistura de reação é auto-suportante e pode ser modelada, se desejado. No processo, a mistura de reação é aquecida em condições de cristalização e na ausência de uma fase líquida externa adicionada, de modo que o excesso de líquido não precisa ser removido do produto de cristalização antes da secagem dos cristais.
