Embodiment Construction

[0022] Typically, JMZ-2 zeolites are prepared from a one-pot synthetic mixture comprising a source of silica, a source of alumina, a first framework organotemplate in the form of a transition metal-amine, and a second organotemplate. Transition metal-amines are used to introduce ionic species of transition metals such as copper into the channels and / or cavities of zeolites during crystallization. Non-framework transition metals introduced into zeolites during their synthesis are referred to herein as in situ metals. In certain embodiments, silica, alumina, templating agent, and seeds are mixed to form a reaction mixture, such as a colloid, which is then heated to promote crystallization. Metal-containing zeolite crystals precipitate out of the reaction mixture. These crystals were collected, washed and dried.

[0023] As used herein, the term "AEI" refers to an AEI-type framework and the term "ITE" refers to an ITE-type framework, as recognized by the Structure Committee of ...

Abstract

A transition-metal-AEI / ITE molecular sieve catalyst and mixed-template synthesis procedure are disclosed.

Description

technical field [0001] The present invention relates to a transition metal zeolite with an AEI framework. The invention also relates to processes for the preparation of such zeolites, and their use as catalysts. Background technique [0002] Zeolites are composed of repeating SiO 4 and AlO 4 Crystalline or quasicrystalline aluminosilicates composed of tetrahedral units. These units are linked together to form a framework of cavities and channels within the crystal with regular molecular dimensions. A variety of synthetic zeolites have been synthesized and each has a unique framework based on a specific arrangement of its tetrahedral units. By convention, each framework type is assigned a unique three-letter designation (eg "AEI") by the International Zeolite Association (IZA). [0003] Synthetic zeolites are usually produced using structure directing agents (SDAs), also known as "templates" or "templates". SDAs are generally complex organic molecules that direct or dir...
