ABSTRACT:
A silica-containing material related to zeolites and referred to hereinafter as FU-1 has the composition 0.6 to 1.4 R.sub.2 O.Al.sub.2 O.sub.3.over 5 SiO.sub.2.O to 40 H.sub.2 O, (where R is a monovalent cation or 1
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.
