PROCEDIMIENTO DE PREPARACION DE UN ALUMINOSILICATO CON ESTRUCTURA TIPO FERRIERITA A PARTIR DE GELES QUE CONTIENEN TETRAMETILAMONIO Y BENCIL-METILPIRROLIDINIO,Y SUS APLICACIONES.

摘要

The present invention comprises a new methiod for hydrothermal synthesis of ferrierite zeolite, using tetramethyl ammounium and benzylmethylpyrrodlidine as directional structure agents, and does not require a subsequent process in order to obtain the acid form of the material. This aspect is very important as it avoids subject treatments of calcination and successive interchanges which degrade the structure of the zeolite. The synthetic ferrierite obtained by means of the invention process has uses in catalytic processes of transformation of hydrocarbons, such as cracking, isomerization, alkylation and polymerization. Specifically, it can be used in the isomerization of butene to isobutene. To be used in catalytic processes the zeolite ferrierite must be heated in an oxidant atmosphere in conditions such that the organic material occluded in the interior is eliminated.
