There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material; and, (b) at least one 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 .ANG.. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger and a synthesis mixture 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 organic material. The metal-containing macrostructures find application in hydrocarbon conversion and in the reduction of emissions.
Cette invention concerne un catalyseur renfermant des macrostructures poreuses composées de: (a) un réseau tridimensionnel de particules d'un matériau inorganique poreux; et (b) au moins un métal. Les particules de la macrostructure occupent moins de 75 % du volume total et forment entre elles un réseau tridimensionnel. Ce réseau est généralement constitué de pores d'un diamètre supérieur à environ 20 .ANG.. Ces macrostructures peuvent s'obtenir de la manière suivante: formation d'un adjuvant renfermant un échangeur ionique inorganique poreux et d'un mélange de synthèse capable de former le matériau inorganique poreux et le métal; transformation du mélange de synthèse en matériau organique poreux et élimination de l'échangeur ionique organique poreux dudit matériau organique. Les macrostructures renfermant un métal peuvent être utilisées pour la transformation des hydrocarbures et la réduction des émissions.
