标题 :Synthesis of ZSM-5 crystals with improved morphology

摘要:Methods are provided for synthesizing crystals having a ZSM-5 framework structure from synthesis mixtures suitable for synthesis of ZSM-12 framework structure crystals in the absence of seed crystals with a ZSM-5 framework structure, such as in the absence of any seed crystals. For synthesis mixtures with a sufficiently high XO 2 :Y 2 O 3 ratio, seeding a synthesis mixture with ZSM-5 seed crystals can result in production of pure phase ZSM-5 crystals with a new morphology. The morphology can include rod-like primary crystallites with a length of about 0.5 μm or less that are organized/aggregated into larger secondary crystal structures. The aggregation of the primary crystallites into a secondary crystal structure can allow for an unexpectedly large mesoporous surface area for the ZSM-5 crystals.

摘要:The invention relates to a multi-autoclave and details of its design, a method for automated synthesis of zeolites in the multi-autoclave, and furthermore, to applications of the multi-autoclave for an automated synthesis which is optimized simultaneously with regard to several synthesis parameters in the synthesis of zeolites. The multi-autoclave consists typically of a pressure vessel/autoclave having from 10 to 10,000 small, separated chambers lined with an inert material, with each chamber typically having a volume of 0.2-2 ml. The chambers preferably are formed as through-going perforations in a central block and the perforations are sealed by balls, septa, stoppers or such which are placed at the bottom and top of each through-going perforation. Metal plates are placed over and under the central block so that a closing mechanism is pressed against the edges of the perforations with sufficient load to enable the chambers to be filled with aqueous mixtures and to be heated to 200° C. without the occurrence of leakage. Top and bottom plates and closing mechanisms can be integrated so that all the perforations are sealed simultaneously when these are placed at the top and bottom sides of the central block.

摘要:The invention is directed to a method of synthesising silicoaluminophosphate and aluminophosphate molecular sieves using synthesis templates that contain at least one template of general formula R 1 R 2 N—R 3 , wherein R 1 and R 2 are independently selected from the group consisting of alkyl groups having from 1 to 3 carbon atoms and hydroxyalkyl groups having from 1 to 3 carbon atoms; R 3 is selected from the group consisting of 4- to 8-membered cycloalkyl groups, optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms, and 4- to 8-membered heterocyclic groups having from 1 to 3 heteroatoms, said heterocyclic groups being optionally substituted by 1 to 3 alkyl groups having from 1 to 3 carbon atoms and the heteroatoms in said heterocyclic groups being selected from the group consisting of O, N, and S. In particular, the present invention relates to the synthesis of silicoaluminophosphate molecular sieves of the CHA framework type having a low silicon to aluminium atomic ratio.

标 题:Process for the synthesis of IZM-2 zeolite in the presence of a template, 1,6-bis(methylpiperidinium)hexane dihydroxide
发明人：MARTINEZ FRANCO RAQUEL; BATS NICOLAS
权利人:IFP ENERGIES NOW
摘要:A novel process is described for the preparation of a microporous crystalline solid, known as IZM-2 microporous solid or IZM-2 zeolite. This novel process consists of carrying out the synthesis of IZM-2 zeolite by conversion/transformation of a zeolite with structure type FAU in a fluorinated medium under hydrothermal conditions. In particular, said novel process consists of carrying out the synthesis of an IZM-2 zeolite in a fluorinated medium starting from a zeolite with structure type FAU used as the source of silicon and aluminium and a specific organic molecule or template comprising two quaternary ammonium functions, namely 1,6-bis(methylpiperidinium)hexane dihydroxide.

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.
