  • Patent number: 10808179
    Abstract: The present invention provides apparatuses and processes for producing high octane fuel from synthesis gas. The process combines transalkylation and zeolite-forming/aromatization in conjunction with a single recycle loop configuration in order to effectively promote the fuel quality, particularly octane rating. The process involves adding a step for enriching octane of the fuel coming from the single recycle loop process. Preferably, the enrichment step takes place in an octane enrichment reactor containing two different catalysts, a zeolite-forming/aromatization catalyst followed by a transalkylation catalyst. The final fuel product preferably has an octane of about 92 to about 112.

  • Patent number: 10214694
    Abstract: This invention relates to a new process to directly produce transportation gasoline from synthesis gas containing principally carbon monoxide, carbon dioxide, and hydrogen. The process entails three sequential catalytic stages with intermediate heat exchange to provide the requisite temperature in each stage, but with no interstage separation. The recycle loop enhances the conversion of the synthesis gas to the desired products and also serves as heat sink for the highly exothermic reactions involved in each stage.

  • Patent number: 9169166
    Abstract: Synthetic fuels are produced from synthesis gas in a four-stage reactor system with a single recycle loop providing the requisite thermal capacity to moderate the high heat release of the reactions and to provide the reactants and reaction environments for the efficient operation of the process. The first reactor converts a portion of the synthesis gas to methanol; the second reactor converts the methanol to dimethylether; the third reactor converts the methanol and dimethylether to fuel; and the fourth reactor converts the high melting point component, durene, and other low volatility aromatic components such as tri- and tetra-methylbenzenes to high octane branched paraffins. A large part of the gas stream of the fourth reactor is recycled to the inlet of the first stage and mixed with the fresh synthesis gas stream. Alternatively, the fresh synthetic gas stream is mixed with the product of the second stage.

  • Patent number: 8722951
    Abstract: This invention relates to fuel compositions for use in combustion engines, such as for motor vehicle and aircraft usage. The fuel composition contains at least 99.5% of aromatic hydrocarbons and paraffinic hydrocarbons. The composition also preferably contains no lead, no multi-ring compound (only single ring compounds are present), less than about 15 ppm sulfur, and/or less than about 5 ppm nitrogen species. The resulting fuel is a drop-in fuel that provides clean burning with little to no engine deposit, high lubricity, high stability, and low corrosion.
