  • Publication number: 20190322946
    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. The water fraction comprises less than 500 ppm of one or more carboxylic acids.

  • Publication number: 20190233734
    Abstract: An easily transportable micro-scale process is described for the direct production of liquid fuels from flare gas, biogas, stranded natural gas, natural gas emissions from methane hydrate dissociation, and other low-volume, gas-phase hydrocarbon resources. The process involves the design of an integrated series of tubular catalytic reactors in which each consecutive catalytic reactor in the series has been designed with larger volumes of catalyst so that a single pass efficiency of about 90% or greater is achieved while keeping the temperatures and pressures of each reactor similar and without requiring tailgas recycling to the reactors. Typically, the process employs a direct fuel production catalyst that produces undetectable, detrimental carboxylic acids in the fuel and catalyst reaction water. As a result, the directly produced, premium fuels are non-corrosive and do not degrade during long-term storage.

  • Publication number: 20180127659
    Abstract: The present invention is directed to unique processes, catalysts and systems for the direct production of liquid fuels (e.g., premium diesel fuel) from synthesis gas produced from natural feedstocks such as natural gas, natural gas liquids, carbon dioxide or other similar compounds or materials. In one aspect, the present invention provides a process for the production of a hydrocarbon mixture comprising the steps of: a) reducing a catalyst in-situ in a fixed bed reactor; b) reacting a feed gas that contains hydrogen and carbon monoxide with the catalyst to produce a hydrocarbon product stream, wherein the hydrocarbon product stream comprises light gases, a diesel fuel and a wax, and wherein the diesel fuel fraction is produced without requiring the hydroprocessing of wax, and wherein the catalyst comprises one or more metals deposited on a gamma alumina support at greater than about 5 weight percent, and wherein platinum or rhenium is included on the support in an amount ranging from about 0.

  • 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.
