Abstract:
A family of crystalline microporous metallophosphates designated AlPO-90 has been synthesized represented by the empirical formula R+rMm2+EPxSiyOz where R is an organoammonium cation, M is a framework metal alkaline earth or transition metal of valence +2, and E is a trivalent framework element such as aluminum or gallium. The compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties for various hydrocarbon conversion processes, and characteristics suitable for efficient adsorption of water vapor in a variety of applications, including adsorption heat pumps. A parameter data system comprising at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data of a parameter of a data of a parameter of at least one unit or stream in fluid communication with and downstream from or upstream to a conversion process comprising at least one reaction catalyzed by SAPO-90.

These metallophosphates are represented by the empirical formula R+rMm2+EPxSiyOz where R is an organoammonium cation, M is a framework metal alkaline earth or transition metal of valence +2, and E is a trivalent framework element such as aluminum or gallium. The AlPO-78 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.
Abstract:
Processes and apparatuses for degrading PFAS into calcium fluoride, carbon dioxide, and water. PFAS are heated and introduced to a calcium base which will degrade the PFAS. The PFAS may be in a stream that is a PFAS enriched stream formed by desorbing the PFAS from an adsorbent which removed the PFAS from a contaminant stream. The PFAS may be desorbed in the presence of the calcium base. The calcium base may be calcium hydroxide, calcium oxide, calcium carbonate, or combinations thereof.
Abstract:
Novel 1-oxa-4-azonium cyclohexane salts are described. These compounds can be used as structure directing agents, and they overcome many of the typical problems associated with OSDA synthesis and subsequent zeolite synthesis. Methods for synthesis of the 1-oxa-4-azonium cyclohexane salts from a variety of starting materials are also described. A substituted hydrocarbon is added to water to form a mixture, and a 1-oxa-4-azacyclohexane derivative is then added. The reaction mixture stirred until a solution containing the 1-oxa-4-azonium cyclohexane salt is obtained.

Abstract:
Coherently grown composites of two zeotypes are described. The coherently grown composites have a crystalline three-dimensional framework of at least AlO2 and PO2 tetrahedral units. The two zeotypes are selected from the group consisting of AFX, LEV, CHA, and ERI. Methods of making the coherently grown composites are also described.
Abstract:
A new family of crystalline microporous metallophosphates designated AlPO-91 has been synthesized. These metallophosphates are represented by the empirical formula Cc+Aa+Mm2+EPxSiyOz where M is a divalent framework metal such as magnesium or zinc, C is a cyclic organoammonium cation, A is an acyclic organoammonium cation, and E is a trivalent framework element such as aluminum or gallium. The AlPO-91 compositions are characterized by a new unique ABC-6 net structure, and have catalytic properties suitable for carrying out various hydrocarbon conversion processes, as well as characteristics suitable for the efficient adsorption of water vapor in a variety of applications, such as adsorption heat pumps.
