Abstract

PROCEDIMIENTO DE OBTENCION EN FORMA SEMICONTINUA DE ZEOLITA A. CONSISTE EN OBTENER POR PRECIPITACION INSTANTANEA UN GEL DE SILICOALUMINATO DE NA, Y DE ALUMINATO DE NA, MEZCLADAS SIMULTANEAMENTE Y EN CONTINUO. ESTA MEZCLA DEBE REALIZARSE RAPIDAMENTE. EL TIEMPO DE REACCION OSCILA ENTRE 30 SEGUNDOS Y 20 MINUTOS. EL GEL OBTENIDO SE TRASVASA POR REBOSE A OTRO REACTOR DOTADO DE AGITADOR Y MANTENIENDO UNA TEMPERATURA CONSTANTE ENTRE 75 Y 100GC QUE PERMITA LA CRISTALIZACION DE ZEOLITA A. LA SOLUCION DE ALUMINATO ESTA SATURADA EN ALUMINA A PRESION ATMOSFERICA. INTERCAMBIADORES CATIONICOS.
