  • Process for the preparation of zeolitic catalysts
    Patent number: 6734323
    Abstract: The present invention relates to a process for the preparation of zeolitic catalysts comprising zeolite and oligomeric silica, which can be used in industrial reactors. The process consists in directly mixing the suspension, resulting from the synthesis of the zeolite, with an oligomeric silica sol, obtained from the hydrolysis of a tetra-alkyl ortho silicate in the presence of tetra-alkylammonium hydroxide, and in subjecting the mixture to rapid drying, by feeding to a spray-dry.
    Type: Grant
    Filed: November 29, 2000
    Date of Patent: May 11, 2004
    Assignees: Enichem S.P.A., Enitecnologie S.P.A.
