  • Patent number: 10865351
    Abstract: The invention relates to a process and an apparatus for producing an olefin-containing feed stream for a steam reforming plant. According to the invention, the olefin-containing hydrocarbon starting material is for this purpose heated, vaporized and catalytically hydrogenated. The hydrogenation product stream obtained is separated in a separation apparatus into a gaseous reforming feed stream, which is fed to a steam reforming plant, and a gaseous recycle stream. Here, the entry temperature of the hydrogenation input stream into the hydrogenation reactor is regulated via the degree to which it is heated and/or via the size of the recycle stream. Safe operation of the hydrogenation reactor over a wide range of olefin contents in the hydrocarbon feed is made possible in this way.

  • Patent number: 10851029
    Abstract: A fuel cell reactor, preferably a solid oxide fuel cell (SOFC) reactor, for performing direct conversion of a hydrocarbon-containing gas to a higher hydrocarbons product is confined by walls, where reactants are flown in the anode compartments and air is introduced to the cathode compartments, and where oxygen is transferred from one side of the walls to the other side to promote or inhibit a chemical reaction. The process for direct conversion of a hydrocarbon-containing gas to a higher hydrocarbons product takes place in the anode compartment of the reactor, in which produced hydrogen, limiting the conversion to the equilibrium, is reacted in situ with oxygen ions transferred from the cathode compartment to produce steam, thereby removing the equilibrium-limiting hydrogen from the reaction.

  • Patent number: 9567264
    Abstract: A process for producing aviation fuel and diesel from renewable feedstock is described. This process involves introducing the renewable feedstock into a hydrogenation and deoxygenation zone, and separating the hydrocarbon effluent from the hydrogenation and deoxygenation zone into an aviation boiling range fraction and a diesel boiling range fraction. The aviation boiling range fraction and diesel boiling range fraction are alternately sent to the isomerization and selective hydrocracking zone. This allows for lower severity isomerization and selective hydrocracking zone operating conditions when processing oils that naturally contain medium and long carbon chains (C8-C18), such as coconut or palm kernel oil. The lower severity operation results in decreased cracking, increasing the yield of aviation fuel product.

The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the C5 to C12 carbon backbone range.

  • Patent number: 8993818
    Abstract: Technologies to convert biomass to liquid hydrocarbon fuels are currently being developed to decrease our carbon footprint and increase use of renewable fuels. Since sugars/sugar derivatives from biomass have high oxygen content and low hydrogen content, coke becomes an issue during zeolite upgrading to liquid hydrocarbon fuels. A self-sustainable process was designed to reduce the coke by co-feeding sugars/sugar derivatives with the paraffin products from hydrogenation of sugars/sugar derivatives. Paraffins without complete conversion result in products with less aromatics and relatively low density compared with the products directly from zeolite upgrading. Thus, the process is more economically favorable.

    Abstract: A multi-stage system converts a hydrocarbon material to an intermediate product in a first stage and a final product in a final stage. The first stage includes a first reaction chamber configured to receive hydrocarbon and process gas. In the presence of energy, the first stage will convert the feedstock into an intermediate product for delivery to a second stage. The second stage includes a second reaction chamber configured to receive the intermediate product and a process gas. When the intermediate product and process gases are fed into the reaction chamber in the presence of energy, a plasma is formed in the second reaction chamber and converts the intermediate product into a liquid fuel.

  • Patent number: 8957266
    Abstract: Provided are processes for making one or more unsaturated oligomeric acids and one or more saturated hydrocarbons. In one form, a process for making one or more saturated hydrocarbons includes oligomerizing one or more unsaturated carboxylic acids having from 4 to 38 carbon atoms in the presence of a molecular sieve catalyst to form one or more unsaturated oligomeric acids including less than 90% by weight of cyclic oligomers, and hydrogenating the one or more unsaturated oligomeric acids via contact with hydrogen in the presence of a hydrogenation catalyst to form one or more saturated hydrocarbons. The oligomerizing of unsaturated fatty acids is from renewable biological sources to form dimer acids. The one or more saturated hydrocarbons are useful as lubricant base oils.

  • Publication number: 20150045602
    Abstract: A process for increasing disproportionation and ring opening reactions an isomerization zone which converts iso-paraffins to normal paraffins. In order to promote these reactions, the amount of C6 cyclic hydrocarbons entering the isomerization zone is reduced. Disproportionation reaction selectivity is observed which produces valuable C3 hydrocarbons and C4 hydrocarbons. Also, a higher ring opening conversion of C5 cyclic hydrocarbons is observed. Conversion of iC4 hydrocarbons, iC5 hydrocarbons, and iC6 hydrocarbons may occur in the same isomerization zone.

  • Publication number: 20150045601
    Abstract: The present invention, a unique method and means of thermal cracking the molecular structure of short chain hydrocarbon vapor for reforming into long chain molecular structure and conversion of a portion to hydrocarbon liquid, much less complicated and complex than presently employed methods and means, combines partial oxidation, fast pyrolysis, and rapid cooling in a unique sequence of events incorporating components, of unique configuration, compact and much more cost effective than the presently employed methods and means of performing gas to liquid conversion that requires a great difference between the cost of the gas vapor feedstock and the selling price of the liquid to justify capital investment in gas to liquid conversion systems. Relatively few conversion systems are operating now and/or under construction.
