A method of synthesising a molecular sieve of DDR framework type. The method comprises: preparing a synthesis mixture capable of forming a molecular sieve of DDR framework type, said synthesis mixture comprising water, a silicon source, optionally a source of a trivalent element X, optionally a source of a pentavalent element Z, optionally a source of hydroxide ions, optionally a source of a metal cation M, a structure directing agent, and seed crystals having a framework type selected from CHA and LEV; said synthesis mixture being substantially free from fluoride ions; heating said synthesis mixture under static crystallization conditions for a time sufficient to form crystals of said molecular sieve of DDR framework type, said crystallization conditions including a temperature of from 100&#xb0; C. to 220&#xb0; C.; and, recovering said crystals of the molecular sieve of DDR framework type from the synthesis mixture.

Process for making molecular sieves

A method of making a crystalline molecular sieve of MFI framework type, preferably ZSM-5, from a synthesis mixture comprising at least one source of tetravalent element (Y), at least one source of trivalent element (X), at least one source of alkali metal hydroxide (MOH), at least one structure directing; (R) and water, said synthesis mixture having the following molar composition: YO, (p)XO: (q) MOH: (r) R: (s) HO, wherein (p) is from 0.005 to 0.025, (q) is from 0.05 to 0.5, (r) is from 0.05 to 0.15 and (s) is from 35 to 45, wherein the ratio of the largest dimension (L) to the smallest dimension (S) of each crystal of the molecular sieve product is at least 5, and the smallest dimension (S) is from 20 nm to 200 nm.

MFI with unusual morphology

Adhesive compositions and a method for selecting adhesive compositions are disclosed herein. Preferred adhesives generally have small domains and/or a homogeneous domain distribution. The method of selecting adhesives is based on size and distribution of the domains.

Adhesive compositions and method for selection thereof

A crystalline material substantially free of framework phosphorus and comprising a CHA framework type molecular sieve with stacking faults or at least one intergrown phase of a CHA framework type molecular sieve and an AEI framework type molecular sieve, wherein said material, in its calcined, anhydrous form, has a composition involving the molar relationship:(n)XO:YO,wherein X is a trivalent element; Y is a tetravalent element; and n is from 0 to about 0.5. The material exhibits activity and selectivity in the conversion of methanol to lower olefins, especially ethylene and propylene.

Chabazite-containing molecular sieve, its synthesis and its use in the conversion of oxygenates to olefins

A new family of crystalline molecular sieves is described having a characteristic XRD pattern as illustrated in FIG.and having three sharp peaks at 2&#x3b8; (CuK) of 8.82, 12.44, and 23.01.

Crystalline molecular sieves

Layers comprising a molecular sieve layer on a porous or non-porous support, having uniform properties and allowing high flux are prepared from colloidal solutions of zeolite or other molecular sieve precursors (particle size less than 100 nm), by deposition, e.g., by spin or dip-coating, or by in situ crystallization.

Molecular sieve layers and processes for their manufacture

A process is described for the manufacture of a crystalline molecular sieve layer on a support, which process comprises impregnation of the support with an impregnating material prior to deposition of a crystalline molecular sieve layer and subsequent removal of substantially all the impregnating material.

Processes for the manufacture of supported materials

The present invention relates to a silicoaluminophosphate molecular sieve comprising at least one intergrown phase of molecular sieves having AEI and CHA framework types, wherein said intergrown phase has an AEI/CHA ratio of from about 5/95 to 40/60 as determined by DIFFaX analysis, using the powder X-ray diffraction pattern of a calcined sample of said silicoaluminophosphate molecular sieve. It also relates to methods for its preparation and to its use in the catalytic conversion of methanol to olefins.
