Silica-containing material FU-1

摘要

A silica-containing material related to zeolites and referred to hereinafter as FU-1 has the composition 0.6 to 1.4 R2O.Al2O3.over 5 SiO2.O to 40 H2O, (where R is a monovalent cation or 1/n of a cation of valency n) and is characterized inter alia by its X-ray diffraction pattern. It can be made by hydrothermal synthesis in presence of methylated quaternary onium compounds. It is useful as a catalyst for hydrocarbon conversion reactions, especially isomerization of xylenes.
