  • Patent number: 10011785
    Abstract: The present invention relates to an integrated process for producing hydrocarbons, wherein feedstock originating from renewable sources is subjected to catalytic hydroprocessing followed by separation of an aqueous component, a heavy component, and a light component, separating carbon dioxide and hydrogen sulfide from said light component to obtain a recycle stream, followed by dividing the recycle stream to a first recycle stream and a second recycle stream, directing the first recycle stream to the hydroprocessing system, and the second recycle stream to a hydrogen plant, where the light component is converted to hydrogen, and directing the hydrogen to the hydroprocessing system.

  • Patent number: 9096802
    Abstract: Method of producing a hydrocarbon composition in which a biomass raw-material is gasified to produce a raw syngas containing carbon monoxide, carbon dioxide and hydrogen, the hydrogen-to-carbon monoxide ratio being about 0.5 to 1.7. A part of the impurities is removed to produce a clean syngas which is fed into a Fischer-Tropsch reactor where a significant part of the carbon monoxide and hydrogen is converted to a hydrocarbon composition containing C4-C90 hydrocarbons. A hydrocarbon composition is recovered which mainly contains hydrocarbons which are solid or semisolid at ambient temperature and pressure and an off-gas of the Fischer-Tropsch reactor, including hydrocarbons which are gaseous at ambient temperature and pressure, is used for producing hydrogen gas. By introducing hydrogen into the clean syngas, the hydrogen to carbon monoxide ratio can be increased and by using off-gas-produced hydrogen, the capacity of the process is significantly improved.

  • Patent number: 8598237
    Abstract: A method for adjusting hydrogen to carbon monoxide ratio of syngas contaminated by sulfur impurities involving a water gas shift (WGS) reaction. In light of the presence of the sulfur impurities, the WGS can be implemented as a sour gas shift. WGS can provide good results by using a non-sulfided catalyst. Conditions can be employed which contribute to further enhanced CO-conversion in the reaction. The hydrocarbons or derivatives thereof obtainable from the method can further be refined and used for production of fuels or lubricants for combustion engines.

  • Publication number: 20130058855
    Abstract: A method of reforming a gasification gas, in order to decompose the impurities comprised in the gas, and a use of a precious metal catalyst in the pre-reforming of gasification gas. The gas can be brought into contact with a metal catalyst in the presence of an oxidizing agent. The reformation can be carried out in several stages, in which case at least in one of the first catalytic zones a noble metal catalyst can be used, and in a secondary reforming stage which follows the first, preliminary reforming zone, the catalyst that can be used is a metal catalyst. Oxygen can be fed separately into each of the catalyst zones. The use of a noble metal catalyst can reduce the risk of deactivation of the metal catalysts and can increase the operating life of the catalyst.

  • Patent number: 7473811
    Abstract: The present invention relates to a process for the hydrogenation of olefins. The process comprises hydrogenation of a feed stock comprising more than 90 wt-% of olefins, carried out in a hydrogenation reactor comprising at least two reaction stages, wherein the feed stock is hydrogenated in the first reaction stage equipped with a cooling circuit and comprising a first and an optional second catalyst bed, and the effluent from the first reaction stage is hydrogenated in the final reaction stage comprising one or more catalyst beds and optionally equipped with a cooling circuit, the process is operated in trickling or pulse flow mode in a three phase reactor with a fixed catalyst bed and at least one catalyst of same or different type is used in each stage, the catalyst having different particle size and/or optionally different shape in at least two stages.

  • Patent number: 7282616
    Abstract: A process for converting an olefin feed to hydrocarbons suitable for fuel components or their feedstock. According to the process, an olefin feed, possibly together with another hydrocarbon feed, is contacted in a reactor with a catalyst in order to produce a hydrocarbon having at least one alkyl side chain. In the invention, the olefin feed is contacted with a particle-form fluidized catalyst in a circulating-bed reactor, wherein the catalyst forms the circulating bed of the reactor. When the operation is carried out in a circulating-bed reactor, the retention time of the feedstock is short. In this case, iso-olefins are formed quite selectively from n-olefins in isomerization. Since the useful life of the catalyst lengthens while the catalytic activity of the bed remains high for a long time, the conversion level also remains high. A long useful life of the catalyst is an economically highly significant advantage.

  • Patent number: 5637777
    Abstract: The invention concerns a process and an apparatus for preparing tertiary ethers. According to the process, C.sub.4 to C.sub.6 isoolefins and possibly heavier olefins contained in the feedstock are reacted with lower aliphatic alcohols, in particular methanol or ethanol, in a catalytic distillation reactor system in order to produce the corresponding ethers. According to the invention, the reaction between the isoolefins and the alcohols is essentially carried out in at least one reactor (5-7) of the kind, which is combined with a distillation column (3) intended for product separation, by conducting at least a part of the liquid flow of the column through the reactor and returning it to a lower tray than the one from which it was taken. At least half of cation exchange resin is placed in the side reactor (5-7). In the process according to the invention, the catalyst can be rapidly changed without stopping the process.
