  • Patent number: 9365466
    Abstract: A system and method for producing a liquid hydrocarbon product from a Fischer-Tropsch process using a synthesis gas feed produced in an oxygen transport membrane based reforming reactor. The system and method involve reforming a mixed feed stream comprising natural gas, hydrogen and the Fischer-Tropsch tail gas, in a reforming reactor in the presence of steam, radiant heat from oxygen transport membrane elements and a reforming catalyst to produce a reformed synthesis gas stream comprising hydrogen, carbon monoxide, and unreformed hydrocarbon gas. The reformed synthesis gas stream is further reformed in an oxygen transport membrane based reforming reactor and conditioned to produce a synthesis gas product stream preferably having a H2/CO ratio of from about 1.7 to about 2.2. The synthesis gas product stream is then synthesized using a Fischer Tropsch process to produce the liquid hydrocarbon product and a Fischer-Tropsch tail gas.

  • Patent number: 9340732
    Abstract: A bitumen and heavy oil upgrading process and system is disclosed for the synthesis of hydrocarbons, an example of which is synthetic crude oil (SCO). The process advantageously avoids the waste attributed to residuum and/or petcoke formation which has a dramatic effect on the yield of hydrocarbon material generated. The process integrates Fischer-Tropsch technology with gasification and hydrogen rich gas stream generation. The hydrogen rich gas generation is conveniently effected using singly or in combination a hydrogen source, a hydrogen rich vapor from hydroprocessing and the Fischer-Tropsch process, a steam methane reformer (SMR) and autothermal reformer (ATR) or a combination of SMR/ATR. The feedstock for upgrading is distilled and the bottoms fraction is gasified and converted in a Fischer-Tropsch reactor. A resultant hydrogen lean syngas is then exposed to the hydrogen rich gas stream to optimize the formation of, for example, the synthetic crude oil.

  • 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: 9090831
    Abstract: A unique process and catalyst is described that operates efficiently for the direct production of a high cetane diesel type fuel or diesel type blending stock from stoichiometric mixtures of hydrogen and carbon monoxide. This invention allows for, but is not limited to, the economical and efficient production high quality diesel type fuels from small or distributed fuel production plants that have an annual production capacity of less than 10,000 barrels of product per day, by eliminating traditional wax upgrading processes. This catalytic process is ideal for distributed diesel fuel production plants such as gas to liquids production and other applications that require optimized economics based on supporting distributed feedstock resources.

  • Patent number: 9090832
    Abstract: The invention relates to a process for synthesising hydrocarbons starting from a feedstock containing synthesis gas. In the process a solid Fischer-Tropsch catalyst is employed in a three-phase reaction section operated so that the catalyst is maintained in suspension in a liquid phase by the circulation of a gaseous phase from the bottom to the top of the reaction section. The process utilizes conditions to control and maintain the homogeneity of the concentration of catalyst particles in the reaction section.

  • Patent number: 9079770
    Abstract: The invention relates to a combined reforming process for making synthesis gas from a desulphurized gaseous hydrocarbon feedstock, wherein the feedstock is split into a first and a second feedstock stream, the first feedstock stream is mixed with steam and fed to a gas heated reformer (GHR) and a steam methane reformer (SMR) operated in series, and the second feedstock stream is mixed with reformed gas coming from the SMR and fed with oxygen to a non-catalytic partial oxidation reformer (POX). The process of the invention enables to produce syngas with adjustable composition and at very high capacity in a single line. The process specifically allows designing a methane-to-methanol production plant with a capacity exceeding 10000 mtpd using technically and economically feasible reforming equipment, and showing high feedstock and energy efficiency. The invention further relates to an integrated process for making methanol from a hydrocarbon feedstock comprising said combined reforming process.
