A new family of rare-earth silicate compositions and the synthetic methods used to prepare them. The materials have open-framework structures and are characterized by their ion-exchange properties. They are represented by the following empirical formula:AMM'SiOwhere A is an exchangeable cation such as sodium, M is at least one element selected from the group of rare-earth elements, and M′ is a framework metal having a valence of +2, +3, +4, or +5. The rare-earth silicate materials have utility in various cation-exchange applications such as dialysis and removal of toxic metals from the gastrointestinal tract.

Rare-earth silicate compositions and their preparation

A process for removing Pbtoxins from bodily fluids involves contacting the bodily fluid with an ion exchange composition to remove the metal toxins in the bodily fluid, including blood and gastrointestinal fluid. Alternatively, blood can be contacted with a dialysis solution which is then contacted with the ion exchange composition. The ion exchange compositions are represented by the following empirical formula:ATiNbSiOhaving either the pharmacosiderite, sitinakite, pharmacosiderite-sitinakite intergrowth topologies or mixtures thereof. There are also compositions comprising the above ion exchange compositions in combination with bodily fluids or dialysis solution. The ion exchange compositions may be supported by porous networks of biocompatible polymers such as carbohydrates or proteins.

Process for removing lead ions from boldily fluids using metallate ion exchange compositions

A family of crystalline microporous metallophosphates designated AlPO-90 has been synthesized represented by the empirical formulaRMEPSiOwhere 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.

Crystalline metallophosphates, their method of preparation, and use

The subject invention is a novel UZM-63 material which comprises globular aggregates of crystallites having a DDR framework type with a mesopore volume of at least 0.025 cc/g, the nanocrystals having an average diameter of less than 60 nm. The novel UZM-63 material is useful for hydrocarbon conversion processes as well as separation applications, particularly the separation of olefins from paraffins.
