Patent number: 8986602Abstract: 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.Type: GrantFiled: August 29, 2011Date of Patent: March 24, 2015Assignee: Directa Plus S.p.A.Inventors: Robert Mercuri, Michael Kasper, Emilie Bekaert, Peter Axmann

Publication number: 20120048064Abstract: 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.Type: ApplicationFiled: August 29, 2011Publication date: March 1, 2012Applicant: Directa Plus S.r.I.Inventors: Michael Kasper, Emilie Bekaert, Chistian Dreer, Peter Axmann
