A catalyst containing nanosize zeolite particles supported on a support material for alkylation reactions, such as the alkylation of benzene to form ethylbenzene, and processes using such a catalyst is disclosed.

The present invention relates to a process of producing a metal-containing catalyst. The process involves mixing a support material with one or more metals in a solution to produce a catalyst comprising a metal-loaded support. The catalyst comprising a metal-loaded support is treated with an atmosphere comprising 0.01 to 100% carbon-containing agents and 0-100% hydrogen at a temperature of 50 to 500 C. to produce a treated metal-containing catalyst on a support. Also disclosed is the resulting treated metal-containing catalyst and its use in a process for converting propane to propylene.

Catalyst and use of the catalyst comprising a molecular sieve belonging to the ABC-6 framework family with disorder in the ABC stacking sequence essentially composed of double-six-ring periodic building units and having a mole ratio of silicon oxide to aluminum oxide from about 8 to about 60.

The present application pertains to family of new crystalline molecular sieves designated SSZ-94. Molecular sieve SSZ-94 is structurally similar to sieves falling within the MTT structure type such as SSZ-32x, SSZ-32, ZSM-23, EU-13, ISI-4, and KZ-1 family of molecular sieves. SSZ-94 is characterized as having magnesium.

The present invention provides a process for preparing a zeolite by hydrothermal heating of silica precursor and alumina precursor along with a combination of two structure-directing organic templates, N,N-dimethyl formamide and 1,6-diaminohexane in the presence of an alkali. The use of two structure-directing organic templates, not only reduces the crystallization time but also enables the preparation of more catalytically active ZSM-22 of submicron crystallite size. The present invention also provides a process of preparing a noble metal containing zeolite catalyst for hydroisomerization of long chain n-paraffins.

A small pore size synthetic zeolite having a degree of crystallinity of at least 80% and comprising at least 0.01 wt % based on the weight of the zeolite of at least one catalytic metal selected from the group consisting of Ru, Rh, Pd, Ag, Os, Ir, Pt, Au, Mo, W, Re, Co, Ni, Zn, Cr, Mn, Ce, Ga and combinations thereof, wherein at least 80% of the catalytic metal is encapsulated in the zeolite, wherein if the zeolite is an aluminosilicate it has a SiO.sub.2:Al.sub.2O.sub.3 molar ratio of greater than 6:1.

The present invention relates to a process for preparing a difunctional catalyst using a zeolite IZM-2, a hydrogenating function and a matrix. The preparation process according to the invention simultaneously allows preferential localization of said hydrogenating function on the surface and/or in the microporosity of zeolite IZM-2 and homogeneous distribution of the hydrogenating function in the catalyst and preferably on zeolite IZM-2 by means of using an impregnation solution comprising specific noble metal precursors combined with the presence of ammonium salts, with a quite precise ratio of ammonium salt to noble metal.
