    • There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material (e.g., zeolites); and, (b) at least one metal (e.g., a catalytically active metal). The particles of the at least one macrostructure occupy less than 75% of the total volume of the at least one macrostructure and are jointed together to form a three-dimensional interconnected network. The three-dimensional interconnected network will usually be comprised of pores having diameters greater than about 20 Å. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger (e.g., a polymer-based ion exchange resin) and a synthesis mixture (e.g., for zeolite formation) capable of forming the porous inorganic material and the at least one metal; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material. The metal-containing macrostructures find application in hydrocarbon conversion (e.g., hydrogenation, dehydrogenation, dehydrocyclization, isomerization, hydrocracking, dewaxing, reforming, conversion of alkyl aromatics, etc.) and in the reduction of emissions of hydrocarbons, carbon monoxide, and/or oxides of nitrogen from an internal combustion engine.
    • 提供了含有多孔宏观结构的催化剂,其包括:(a)多孔无机材料(例如沸石)颗粒的三维网络; 和(b)至少一种金属(例如催化活性金属)。 所述至少一个宏观结构的颗粒占据所述至少一个宏观结构的总体积的小于75%并且连接在一起以形成三维互连网络。 三维互连网络通常由直径大于约的孔组成。 宏观结构可以通过形成含有多孔有机离子交换剂(例如,基于聚合物的离子交换树脂)和能够形成多孔无机材料的合成混合物(例如,用于沸石形成)和至少一种金属 ; 将合成混合物转化为多孔无机材料; 并从无机材料中除去多孔有机离子交换剂。 含金属的宏观结构可用于烃转化(例如氢化,脱氢,脱氢环化,异构化,加氢裂化,脱蜡,重整,烷基芳族化合物的转化等)和减少烃,一氧化碳和/或 来自内燃机的氮氧化物。
