    • This invention relates to the synthesis of large pore composite molecular sieves and to the synthetic large pore composite molecular sieves so produced. The molecular sieves of the invention have the same general utilties of the comparable molecular sieves of the prior art but have been found to be superior catalysts and absorbents. This invention relates to a hydrothermal synthesis of large pore molecular sieves from nutrients, at least one of which contains an amorphous framework-structure, and which framework-structure is essentially retained in the synthetic molecular sieve. This invention stems from a discovery that the intrinsic porosity characteristics of a nutrient that possesses an amorphous cation oxide-framework can be substantially retained in the final molecular sieve containing product formed by a hydrothermal process by carefully controlling the conditions under which the hydrothermal process is conducted. For example, the invention contemplates retention of the particle size in a final molecular sieve-containing product that corresponds with that of an amorphous cation oxide-framework nutrient used in its manufacture. This invention drives the selection of process conditions to achieve one or more of macro and meso porosity ("large pore composite porosity") in the final molecular sieve product as a direct product of the hydrothermal reaction producing the molecular sieve. The invention allows the production of a molecular sieve that is in situ incorporated in the framework morphology of a solid cation oxide-framework used in the molecular sieve's manufacture.
    • 本发明涉及大孔复合分子筛的合成以及如此生产的合成大孔复合分子筛。 本发明的分子筛具有与现有技术相当的分子筛相同的一般用途,但已被发现是优异的催化剂和吸收剂。 本发明涉及从营养物质中大量分子筛的水热合成,其中至少一种含有无定形骨架结构,其中骨架结构基本上保留在合成分子筛中。 本发明源自一个发现,即通过仔细控制进行水热处理的条件,具有无定形阳离子氧化物 - 框架的营养物质的固有孔隙特性可以基本上保留在通过水热法形成的含最终分子筛的产品中 。 例如,本发明考虑到在与其制造中使用的无定形阳离子氧化物 - 骨架营养物相当的最终的含分子筛的产品中保留粒度。 本发明驱动工艺条件的选择,以实现最终分子筛产物中作为产生分子筛的水热反应的直接产物的宏观和中孔多孔性(“大孔复合孔隙率”)中的一种或多种。 本发明允许生产分子筛,其原位掺入分子筛制造中使用的固体阳离子氧化物框架的骨架形态。

    • An improved process is provided for forming ketones from the corresponding olefins by vapor phase oxidation of the olefin in the presence of water vapor, and optionally in the additional presence of molecular oxygen employing a heterogeneous catalyst comprising at least one member selected from the group consisting of Ce, Nd and La and compounds and complexes thereof, optionally containing at least one metal compound or complex selected from the group consisting of Group VIB metals and Group VIII noble metals, and mixtures thereof. It has been surprisingly found that these catalysts effect the formation of ketones in high selectivities with minimal selectivities to the undesirable carbon dioxide and carbon monoxide by-products.
    • 提供了一种改进的方法,用于在水蒸气存在下通过气相氧化烯烃从相应的烯烃形成酮,并且任选地在额外存在分子氧的情况下,使用包含至少一种选自以下的组分的多相催化剂: Ce,Nd和La及其化合物和络合物,任选地含有至少一种选自VIB族金属和VIII族贵金属的金属化合物或络合物,及其混合物。 已经令人惊奇地发现,这些催化剂以高选择性的方式影响酮的形成,对不期望的二氧化碳和一氧化碳副产物的选择性最小。
