Abstract

"SìNTESE DE ZEóLITOS E ZEóTIPOS DE POROS GRANDES, ZEóLITOS E ZEóTIPOS OBTIDOS E USO DESTES", sendo os materiais de zeólito de poros grandes relacionados estruturalmente com o zeólito Beta a caracaterizados pelo fato de apresentarem o meio de síntese com pH relativamente baixo e o uso de âninons F^ -^ como mineralizadores, dita invenção referindo-se também aos materiais assim obtidos, caracaterizados pela sua estabilidade térmica muito elevada, baixa concentração de defeitos SiO^ -^ ou SiOH, ampla faixa de composição química, poros grandes e pelo fato de a sua calcinação permitir a obtenção da forma ácida sem o uso do processo de troca catiónica. Apesar de os referidos materais estarem relacionados com o zeólitos Beta, eles apresentam, ocasionalmente, diferenças substanciais com relação ao zeólito Beta. Também reinvindicado é o uso do meterial obtido no processo catalítico de transformação de hidrocarbonetos e em processo de oxidação. O Método compreende aquecer a 363-473K uma mistura de reação contendo uma fonte de pelo menos um elemento tetravalente T(IV), opcionalmente uma fonte de uma elemento T(III), opcionalmente H~ 2~O~ 2~, um cátion orgânico diretor de estrutura, uma fonte de ânios F^ -^ e água, não sendo necessária a presença de cátions alcalinos.
