  • Publication number: 20160347681
    Abstract: Disclosed is a method for converting an alkyl halide to an olefin. The method can include contacting a zeolite catalyst having a chemical formula of My/nH(x-y)AlxSi(96-x)O192, where M is a metal cation having a valence of n under reaction conditions sufficient to produce an olefin hydrocarbon product comprising C2 to C4 olefins. M can include cations of metals from Groups IA, IIA, IIIA. IVB, VB, VIB VIIB, IB, IIB, IIIA or IVA, or any combination of metal cations thereof and y is 0.4?y?5.0.

  • Publication number: 20120209042
    Abstract: The invention provides a process for selective hydrogenation of alkynes and other unsaturated hydrocarbons, such as acetylene and diolefins, with a catalyst comprising Pd and, optionally, at least one metal from the IA, IB, IIIA, IIIB, VB, or VIIIB Groups, where the metals are supported on a porous material, such as titania. If the process is in the absence of carbon monoxide (CO) in the feed, at least one metal from the IA, IB or IIIA Groups should be present in the catalyst, e.g., potassium, boron or silver. If the carbon monoxide (CO) is present in the feed, the catalyst consists essentially of Pd supported on a porous material, such as titania.

  • Patent number: 7449426
    Abstract: Disclosed is a catalyst composition which does not contain antimony or molybdenum for the vapor phase ammoxidation of alkanes of the general empirical formula: VWaBibMcOx wherein M is one or more elements selected from sodium, cesium, magnesium, calcium, barium, boron, yttrium, indium, aluminum, gallium, tin, titanium, silicon, zirconium, germanium, niobium and tantalum, a is 0.2 to 10, b is 0.5 to 5, c is 0 to 10 and x is determined by the valence requirements of the elements present. The catalyst precursor is precipitated from a solution or slurry of compounds of vanadium, tungsten, bismuth and, optionally, M, then separated, dried and calcined to give a phase or combination of phases active in the ammoxidation of low-weight paraffins to the corresponding unsaturated mononitriles. Nitriles may be produced in a gas phase catalytic reaction of alkanes with ammonia and oxygen in the presence of the catalyst.

  • Patent number: 7186670
    Abstract: A process for the vapor phase ammoxidation of alkanes and olefins with a catalyst of the general empirical formula: VSbaMbQcOx wherein M is at least one element selected from magnesium, aluminum, zirconium, silicon, hafnium, titanium and niobium, Q is at least one element selected from rhenium, tungsten, molybdenum, tantalum, manganese, phosphorus, cerium, tin, boron, scandium, bismuth, gallium, indium, iron, chromium, lanthanum, yttrium, zinc, cobalt, nickel, cadmium, copper, strontium, barium, calcium, silver, potassium, sodium and cesium, a is 0.5 to 20, b is 2 to 50, c is 0 to 10 and x is determined by the valence requirements of the elements present. The process has a co-feed of gaseous carbon dioxide with an alkane (paraffin) and/or alkene, ammonia and an oxygen-containing gas which react in the presence of the catalyst to form a nitrile and by-products.
