    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 vapour 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.

  • Publication number: 20140350131
    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 vapour 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.

  • Publication number: 20140345546
    Abstract: A Coal-to-Liquid Fuels production process by which carbon dioxide (CO2) exhaust by-products are significantly reduced, if not eliminated, through a system comprising the generation of a first hydrogen (H2) product and carbon from coal and generating carbon monoxide (CO) by reacting the Carbon (C) with CO2. A second hydrogen (H2) product is generated through catalyzation of water, methane reformation, electrolysis of water, or other reaction processes. Carbon monoxide (CO) is reacted with the first and second hydrogen (H2) products to form a first hydrocarbon group having Olefins. The first hydrocarbon group, as Olefins, are further reacted to form C1-40 alcohols, Kerosene, Gasoline, Diesel Fuel, and Jet Fuel, and combinations thereof. At least a portion of the finished fuel blends are optionally used to generate electricity for use in the fuels production process or for distribution to an external power grid.

  • Patent number: 8889746
    Abstract: An enhanced Fischer-Tropsch process for the synthesis of sulfur free, clean burning, hydrocarbon fuels, examples of which include syndiesel and aviation fuel. Naphtha is destroyed in a syngas generator and recycled as feedstock to an Fischer-Tropsch (FT) reactor in order to enhance the production of syndiesel from the reactor. The process enhancement results is the maximum production of formulated syndiesel without the formation of low value by-products.

  • Patent number: 8791165
    Abstract: This invention discloses a method for making a dimethylether (DME) product from a synthesis gas (syngas) in the presence of a catalyst in a fluid pluralized bed reactor operating in the gas phase. The reactions generate a significant amount of heat and the heat management is balanced between supplying quench recycle syngas to the pluralized sections along the reactor and also by controlling the preheat temperature of the reactant streams. Gas phase fluidization of the catalyst is controlled so that the pluralized reactive zones are maintained in a backmix configuration.
