    摘要: In a method of synthesizing an aluminophosphate or metalloaluminophosphate molecular sieve, a synthesis mixture is provided comprising water, a source of aluminum, a source of phosphorus, optionally a source of a metal other than aluminum, a tertiary amine, and an alkylating agent capable of reacting with said tertiary amine to form a quaternary ammonium compound capable of directing the synthesis of said molecular sieve. The synthesis mixture is maintained under conditions sufficient to cause the alkylating agent to react with the tertiary amine to produce the quaternary ammonium compound and to induce crystallization of the molecular sieve.

    摘要: The invention relates to a method for converting an oxygenated hydrocarbon feedstock into an olefin product comprising: (a) forming a CHA framework type aluminosilicate sieve catalyst made from a substantially fluoride-free synthesis mixture comprising silicon and aluminum sources, a slurry medium, and a template, wherein the sieve is substantially free from framework phosphorus and exhibits a Si/Al ratio from about 40-60; (b) optionally formulating the molecular sieve catalyst with an oxidized aluminum-containing precursor matrix material and a clay binder to form a molecular sieve catalyst composition; (c) activating the catalyst by removing/decomposing the template; and (d) contacting the activated catalyst with the feedstock under conditions sufficient to form an olefin product comprising ≧about 65% by weight, on a water-free basis, of ethylene and propylene and having an ethylene-to-propylene ratio ≧about 1.2. Ethylene- and propylene-containing polymers can be formed from the olefin product.
