  • Patent number: 7473814
    Abstract: The invention relates to a process for producing ethane comprising contacting methane with a metal catalyst selected from metal hydrides, metal organic compounds and mixtures thereof. It also relates to a process for the conversion of methane to carbon-containing products comprising contacting methane with a metal catalyst comprising at least one metal, Me, chosen from the lanthanides, the actinides and the metals from Groups 2 to 12 of the Periodic Table of the Elements, so as to produce ethane in a proportion of at least 65%, especially at least 98% or 99% by weight with respect to carbon-containing products formed in the process. The process can be a single-step process, preferably carried out under conditions involving a non-oxidative catalytic coupling of methane, in particular under operating conditions maintained substantially constant, preferably continuously, during the ethane production, e.g. at a temperature ranging from ?30° C. to +80° C., preferably from 20° C. to 500° C.

  • Patent number: 6727397
    Abstract: The present invention relates to a process for manufacturing alkanes, comprising, as main stage, a reaction resulting from bringing methane into contact with at least one other starting alkane (A) in the presence of a catalyst based on a metal M capable of catalyzing a metathesis of alkanes. The reaction results in the formation of at least one or two final alkanes (B) having a number of carbon atoms less than or equal to that of the starting alkane (A) and at least equal to 2. Preferably the catalyst comprises a hydride of a metal M grafted to and dispersed over a solid support. The metal M may be chosen from transition metals, lanthanides and actinides. The present invention also relates to the use of a catalyst capable of catalyzing a metathesis of alkanes in 3 reaction resulting from bringing methane into contact with at least one other starting alkane (A).

  • Patent number: 6555721
    Abstract: Process for producing a mono-olefin from a feedstock containing a paraffinic hydrocarbon comprising feeding a gaseous paraffinic hydrocarbon-containing feedstock and a molecular oxygen-containing gas to an autothermal cracker wherein they are reacted in the presence of a catalyst capable of supporting combustion beyond the normal fuel rich limit of flammability to produce a product comprising one or more mono-olefin(s) and synthesis gas, and wherein the autothermal cracker is operated at a temperature greater than 650° C. and at a pressure of greater than 5 bar absolute. The product is separated into a high pressure fuel gas stream comprising methane, carbon monoxide and hydrogen and a stream comprising one or more olefins and recovering the one or more olefin(s).

  • Patent number: 6469225
    Abstract: A process for the manufacture of alkanes comprising a cross-metathesis reaction between at least one starting alkane (A) and one organometallic compound (B) fixed to an inorganic support and comprising a metal bonded to at least one hydrocarbon-comprising radical. The reaction leads to the formation of at least one other alkane (C) which is a higher or lower homologue of the starting alkane (A), by cleavage of the hydrocarbon-comprising radical with the metal of the organometallic compound (B) and recombination of the radical with at least one other radical originating from a cleavage of the starting alkane (A). The metal of the compound (B) preferably is selected from transition metals, lanthanides and actinides, and the hydrocarbon-comprising radical of the compound (B) preferably is selected from alkyl, alkylidene and alkylidyne radicals.

  • Publication number: 20020143220
    Abstract: A process for the production of a mono-olefin from a feedstock comprising a paraffinic hydrocarbon which process comprises the steps of: (a) feeding the feedstock and a molecular oxygen-containing gas to an autothermal cracker wherein they are reacted by oxidative dehydrogenation to form a product comprising one, or more, mono-olefin(s) and synthesis gas, (b) separating the product from step (a) into a synthesis gas-containing stream and one, or more, olefins and recovering the one, or more, olefin(s), (c) contacting synthesis gas-containing stream separated in step (b) with either, (i) a catalyst for the conversion of synthesis gas to methanol under conditions whereby synthesis gas is converted to methanol; or (ii) a catalyst for the water gas shift reaction under conditions whereby carbon monoxide in the synthesis gas is converted by reaction with water to hydrogen and carbon dioxide and thereafter recovering hydrogen; or (iii) a catalyst for the conversion of synthesis gas to hydrocarbons under conditions

  • Patent number: 6395944
    Abstract: Process for the production of a mono-olefin and a hydrocarbon fraction boiling in the diesel range in which (I) a gaseous paraffinic hydrocarbon-containing feedstock and a molecular oxygen-containing gas are fed to an autothermal cracker wherein they are reacted in the presence or absence of a catalyst capable of supporting combustion beyond the normal fuel rich limit of flammability under conditions whereby the feedstock is oxidatively dehydrogenated to a product comprising one or more mono-olefin(s) and synthesis gas. The product from step (I) is separated into synthesis gas and one or more mono-olefin(s) and the one or more mono-olefin(s) are recovered. Synthesis gas separated in step (II), optionally together with additional synthesis gas, is fed to a Fischer Tropsch (FT) reactor containing an FT catalyst wherein the synthesis gas is reacted under FT conditions to produce an FT product containing naphtha and hydrocarbons boiling in the diesel range.

  • Patent number: 5723713
    Abstract: This invention relates to a process for the converting ethylene to a mixture of 1-olefins by (a) feeding ethylene through an oligomerization catalyst bed to form an oligomer predominating in C2-C6 olefins and (b) feeding the oligomer, optionally admixed with fresh ethylene, containing at least 50% by volume ethylene, through a metathesis catalyst bed to form a product predominating in C2-C6 1-olefins. Steps (a) and (b) can be carried out sequentially and in a single reactor under the same conditions of reaction temperature and pressure. This mitigates the perceived disadvantages of low activity and low conversions of relatively inexpensive oligomerization catalysts and forms oligomer having the desired distribution of 1-olefin components for use as comonomer in a polyolefin process.
