Patent number: 11319284Abstract: In a process for the synthesis of a nitrile by endothermic catalyzed reaction of ammonia with a hydrocarbon using heating obtained by passing an alternating current through a metallic coil, the endothermic reaction between ammonia and the hydrocarbon takes place in a reactor with direct inductive heating in the reaction zone. The heating is extremely fast, which makes the reaction practically instantaneous.Type: GrantFiled: April 24, 2017Date of Patent: May 3, 2022Assignee: HALDOR TOPSØE A/SInventors: Poul Erik Højlund Nielsen, Burcin Temel McKenna, John Bøgild Hansen, Rasmus Munksgård Nielsen

Patent number: 10987646Abstract: A reactor system for dehydrogenation of alkanes in a given temperature range upon bringing a reactant stream including alkanes into contact with a catalytic mixture. The reactor system includes a reactor unit arranged to accommodate the catalytic mixture, where the catalytic mixture includes catalyst particles and a ferromagnetic material. The catalyst particles are arranged to catalyze the dehydrogenation of alkanes. The ferromagnetic material is ferromagnetic at least at temperatures up to an upper limit of the given temperature range. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalytic mixture is heated to a temperature within the temperature range by means of the alternating magnetic field. Also, a catalytic mixture and a method of dehydrogenating alkanes.Type: GrantFiled: October 24, 2016Date of Patent: April 27, 2021Assignee: HALDOR TOPSØE A/SInventors: Poul Erik Højlund Nielsen, Rasmus Munksgård Nielsen, John Bøgild Hansen, Burcin Temel McKenna

Patent number: 7825287Abstract: High octane C7 hydrocarbons, particularly 2,2,3-trimethylbutane (“triptane”) and 2,2,3-trimethyl-but-1-ene (“triptene”) (collectively “triptyls”) are produced by homologation of a feed comprising dimethyl ether and/or methanol and optionally including one or more aliphatic hydrocarbons in the presence of certain acidic zeolite catalysts. The process can be carried out at temperatures lower than those previously used for conversion of dimethyl ether and/or methanol to higher alkanes, including C7 alkanes, and results in selective production of triptane and/or triptene with relatively little isomerization to or production of other C7 alkanes.Type: GrantFiled: March 28, 2008Date of Patent: November 2, 2010Assignee: The Regents of the University of CaliforniaInventors: John Ahn, Burcin Temel, Enrique Iglesia
