PROCESS FOR THE SYNTHESIS OF FERRISILICATE ZEOLITES, PRODUCTS THUS OBTAINED AND THEIR USE

摘要

The ferrizeolite according to the invention is characterised by… a) the following approximate chemical formula:… M2/nO.Fe2O3.xSiO2… where M denotes a proton and/or a metal cation… n is the valency of the said cation… x is a number between 40 and 1000… b) an x-ray diffraction pattern, and… c) a fluorine content of between approximately 0.01% and 1.6% by weight. …Application especially to processes for converting methanol into hydrocarbons, toluene alkylation with methanol and catalytic cracking of hydrocarbons.
