Abstract: Hydrocarbon conversion processes using a new family of zeolites identified as UZM-8 and UZM-8HS are described. The UZM-8 and UZM-8HS are related in that the UZM-8HS are derived from the UZM-8 zeolite by treating the UZM-8 with a fluoro-silicate salt, an acid, etc. The UZM-8 and -8HS have unique x-ray diffraction patterns. These zeolites can be used in alkylation of aromatics, transalkylation of aromatics, isomerization of aromatics and alkylation of isoparaffins.

Abstract: An aluminosilicate zeolite and substituted versions designated UZM-15 have been synthesized. These zeolites are prepared using an organo-ammonium cation as a template in which at least one organic group has at least 2 carbon atoms. An example of such a cation is diethyldimethyl-ammonium cation. The template can optionally comprise other organoammonium cations, alkali metals and alkaline earth metals. These UZM-15 materials can be dealuminated by various processes to provide UZM-15HS compositions. Both the UZM-15 and UZM-15HS compositions are useful as catalysts or catalyst supports in various process such as the conversion of cyclic hydrocarbons to non-cyclic hydrocarbons and olefin oligomerization.

Abstract: A family of crystalline aluminosilicate zeolites designated UZM-5HS and derived from UZM-5 have been synthesized. The aluminum content of the UZM-5HS is lower than that of the starting UZM-5 thus changing its ion exchange capacity and acidity.

Abstract: An aluminosilicate zeolite and substituted version designated UZM-16 have been synthesized. These zeolites are prepared using benzyltrimethyl-ammonium (BzTMA) cation or a combination of BzTMA and at least one other quaternary ammonium cation These zeolites have a structure that is related to offretite, but shows structurally different and distinct features. The UZM-16 zeolites can be dealuminated to form UZM-16HS zeolites which have different acidity, porosity and ion-exchange properties. Both UZM-16 and UZM-16HS are useful in various hydrocarbon conversion processes.

Abstract: A new family of crystalline metal oxide compositions have been synthesized. These compositions are described by the empirical formula: AnTaMxM′yM″mOp where A is an alkali metal cation, ammonium ion and mixtures thereof, M is tungsten, molybdenum, or mixtures thereof. M′ is vanadium, antimony, tellurium, niobium and mixtures thereof, and M″ is titanium, tin, indium and gallium, aluminum, bismuth and mixtures thereof. M′ and M″ are optional metals. These compositions are characterized by having an x-ray diffraction pattern having at least one peak at a d spacing of about 3.9 Å. These materials can be used in various hydrocarbon conversion processes such as dehydrogenation.

Abstract: A new family of crystalline metal oxide compositions have been synthesized. These compositions are described by the empirical formula: AnNbMxM′yM″mOp where A is an alkali metal cation, ammonium ion and mixtures thereof, M is tungsten, molybdenum, or mixtures thereof. M′ is vanadium, tantalum and mixtures thereof, and M″ is antimony, tellurium and mixtures thereof. M′ and M″ are optional metals. These compositions are characterized by having an x-ray diffraction pattern having at least one peak at a d spacing of about 3.9 Å. A hydrothermal synthesis procedure as well as processes using the composition, e.g., ammoxidation of propane, are also disclosed.

Abstract: A new family of crystalline and microporous compositions having indium and silicon as essential framework elements have been synthesized. These compositions are characterized by unique x-ray diffraction patterns and an empirical formula of:A.sub.p (In.sub.1-n M.sub.n).sub.y Si.sub.1-z Ge.sub.z O.sub.xwhere A is a cation such as sodium or potassium and M is a metal having a valence of +3, +4 or +5 such as iron (+3), titanium (+4) and niobium (+5).
