  • Patent number: 12152203
    Abstract: The present invention generally relates to improved catalysts that provide for reduced product contaminants, related methods and improved reaction products. It more specifically relates to improved direct fuel production and redox catalysts that provide for reduced levels of certain oxygenated contaminants, methods related to the use of those catalysts, and hydrocarbon fuel or fuel-related products that have improved characteristics. In one aspect, the present invention is directed to a method of converting one or more carbon-containing feedstocks into one or more hydrocarbon liquid fuels. The method includes the steps of: converting the one or more carbon-containing feedstocks into syngas; and, converting the syngas to one or more hydrocarbons (including liquid fuels) and a water fraction.

  • Patent number: 11994345
    Abstract: The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source.

  • Patent number: 9909071
    Abstract: The disclosed embodiments relate to a process ideal for small scale (distributed) gas to liquids production by recycling and processing some side (non-targeted) products. During operation, the system produces a range of hydrocarbon outputs. The disclosed embodiments recycle non-targeted outputs to maximize the output of targeted hydrocarbon products. Recycled outputs include waxes, light gases and syngas. These embodiments allow for, but are not limited to, the efficient production of high cetane diesel fuel through the recycling of long-chain hydrocarbon wax and short-chain light. Process efficiency is further increased through the recycling of tail-gas produced from catalytic reactions.

  • Patent number: 9896626
    Abstract: An apparatus for a distributed manufacturing plant that allows direct, economical production of transportation fuels and/or chemicals at remote sites is described. The production plant employs two primary integrated systems consisting of a syngas generator and a catalytic process that are used to directly produce fuels and chemicals. The syngas generator utilizes oxygen anions, produced from a ceramic membrane system, to generate high quality syngas directly at pressures of about 100-600 psia. The tail gas and water containing hydroxyl-alkanes from the catalytic process are recycled into the syngas generator, in automatically controlled proportions, to regulate the hydrogen to carbon monoxide within the preferred H2/CO stoichiometric range of about 1.8-2.4. The primary products produced directly from the plant include reformulated gasoline blendstocks, #1 diesel fuels, and #2 diesel fuels.
