Process for preparing zeolite beta and use thereof

Method for preparing zeolite beta which method comprises crystallization of zeolite beta from a solution comprising a template, a silicon source and an aluminum source in which the template is polymeric compound comprising ionizable polydiallyldimethylammonium (PDADMA) cationcrystallization. Furthermore, the present invention provides the use of thus prepared zeolite beta in catalysts for hydrocarbon conversions.
