    摘要: Molecular sieves (often loosely termed microporous materials) contain an actinide in combination with atoms selected from the group consisting of oxygen, fluorine, phosphorus, transition metals and mixtures thereof. The molecular sieve material may contain a template species, which suitably comprises an organic template molecule and/or a cationic metal species; it may also contain water. Additionally, it may contain a dopant, usually in a minor amount; suitable dopants include transition metals to modify the catalytic properties of the materials. Preferred molecular sieves comprise layered structures in which layers containing actinide in combination with atoms selected from the group consisting of oxygen, fluorine, phosphorus, transition metals and mixtures thereof have organic templates and/or cationic metal species located between them. In one class of materials, the layers contain an oxoanion (preferably a phosphate, notably orthophosphate, or a transition metal oxoanion); in this class, the actinide may usually be represented as an oxo ion, expecially an oxocation. In another class of materials, the layers contain actinide and fluorine. Exemplary materials have U/P/O or U/F frameworks.

    摘要: A novel synthetic dioctahedral smectite layered clay, a process for preparing the clay and a process using the clay is disclosed. The clays that are prepared are gallium/silicon, gallium/germanium, or aluminum/germanium smectite clays. The clay is prepared from a reaction mixture containing reactive sources of the metals, i.e., aluminum, silicon, gallium and germanium, a templating agent and water. This reaction mixture is reacted at a pH of 8.5 to 14, a temperature of 150 to 210 o C for a time of 1 to 20 days to give a desired composition. The clay compositions of the instant invention can be used to catalyze various hydrocarbon conversion processes such as alkylation and hydrocracking.
