  • Patent number: 8986602
    Abstract: The reactor is used for producing nano-particles of metal from volatile moieties in flow through mode. The reactor comprises at least a first feeder and a second feeder on one end of the vessel. The first feeder feeds the moiety in the form of an educt fluid into the reactor. This fluid is a mixture of metal moieties and a bearer fluid, entering the reactor in a vaporized state, in which the bearer fluid is used as a carrier gas. The second feeder is used as a radiator means to heat up the educt fluid within the reactor. By providing the heating fluid through the second feeder control over some environmental conditions like ambient temperature within the reactor is achieved and dissociation of the metal moieties under such controlled conditions leads to quantitative production of selected nano-particle morphologies.

  • Publication number: 20120048064
    Abstract: A production complex is used for producing nano-particles of metal from volatile moieties like metal carbonyls in a flow through reactor. The carbonyls are fed into the reactor through a first feeder, which is a moiety feeder. The moiety, a mixture of metal carbonyl and a bearer fluid, is entering the reactor in a vaporized state. Decomposition of carbonyls is carried out by controlled ambient temperature within the reactor, which is provided by means of a heated inert gas through a heating feed line of the production complex into a second feeder of the reactor, when the production complex is in an operational state. Gases like nitrogen are heated up in units of the production complex as heating feed. The gas supply unit in pre-operational state is used to provide inert gas for cleaning a carbonyl feed line in order to improve the quality of nano-particles of metal produced.

  • Publication number: 20090035208
    Abstract: The invention relates to nanoporous catalyst particles having a spherical and/or spheroidal secondary structure, which contain, as catalytically active constituents, transition metals and/or oxides or precursors thereof. The invention also relates to a method for producing the nanoporous catalyst particles, during which, by means of a precipitation process, precursors with a spherical and/or spheroidal preliminary shape are produced from soluble compounds of the active constituents, and these morphologically pre-shaped precursors are, in a thermal activation step, transformed into nanoporous catalyst particles having a spherical and/or spheroidal secondary structure. The inventive catalyst particles can be used in the production of ceramic materials, as electrode materials in electrochemical cells or in fuel cells, as storage materials for chemical species and, in particular, in the production of carbon nanoparticles in the form of small tubes or fibers.
