  • Patent number: 11111142
    Abstract: Processes and catalysts for producing hydrogen by reforming methane are disclosed, which afford considerable flexibility in terms of the quality of the reformer feed. This can be attributed to the robustness of the noble metal-containing catalysts described herein for use in reforming, such that a number of components commonly present in methane-containing process streams can advantageously be maintained without conventional upgrading (pretreating) steps, thereby improving process economics. This also allows for the reforming of impure reformer feeds, even in relatively small quantities, which may be characterized as complex gas mixtures due to significant quantities of non-methane components. A representative reforming catalyst comprises 1 wt-% Pt and 1 wt-% Rh as noble metals, on a cerium oxide support.

  • Patent number: 11078077
    Abstract: A method for producing synthesis gas may involve introducing a hydrocarbon-containing coke-oven gas and a carbon dioxide-containing converter gas into a first reaction zone where hydrogen present in the hydrocarbon-containing coke-oven gas reacts at least partly with carbon dioxide to form water, which reacts thermally with hydrocarbon to form synthesis gas containing carbon monoxide and hydrogen. The method may further involve introducing an oxygen-containing gas in a second reaction zone, and using the oxygen-containing gas and some hydrogen from the first reaction zone to produce thermal energy. Still further, the method may involve supplying the thermal energy produced in the second reaction zone to the first reaction zone.

  • Patent number: 10633317
    Abstract: Utilizing the common knowledge formula for creation of methanol CO2+3H2?CH3OH+H2O; for each mole of carbon dioxide, three moles of hydrogen are needed to produce one equivalent unit of methanol. Mixing two gases and producing methanol can be accomplished per the one-line diagram concept, FIG. 1, and gas mixing apparatus, FIG. 2; under high pressure (from 3250 to 5000 psi) and high temperature (750 to 800° F.) without the presence of a catalyst. The hypothesis in this case is that the closer the mixing temperature is to the auto-ignition of hydrogen, the higher is the quality of the mixing environment. The mixing temperature in my invention is guided by the auto-ignition of hydrogen in this case (auto-ignition for hydrogen is 932° F. (or 500° C.) and the auto-ignition temperature for methanol is 867° F. (or 464° C.). After mixing the two gases, the result is methanol and water. The first step in this stage is to cool the substance by way of cooling tower, followed by a pressure lowering tank.

    Abstract: A syngas generator is disclosed as an exothermic gas generator that is configured to accommodate high combustion temperatures of a natural gas/oxygen flame. The generator consists of four sections: a heavily insulated combustion chamber, a catalyst chamber, a spray chamber, and a heat exchanger. In an example embodiment, these four sections are arranged in series and are tightly bolted together to form a gas tight system. Natural gas, oxygen and steam are supplied to a burner at the inlet end of the combustion chamber. This mixture is ignited and the resulting hot process gas is then fed into a catalyst bed where it reacts with the steam and is converted to carbon monoxide and hydrogen (syngas). The syngas is fed to a Fischer-Tropsch unit to create liquid fuel.

  • Patent number: 10597294
    Abstract: Among other things, the present invention encompasses the applicant's recognition that epoxide carbonylation can be performed industrially utilizing syngas streams containing hydrogen, carbon monoxide and varying amounts carbon dioxide. Contrary to expectation, the epoxide carbonylation reaction proceeds selectively in the presence of these mixed gas streams and incorporates excess CO in the syngas stream into valuable chemical precursors, resulting in hydrogen streams substantially free of CO. This is economically and environmentally preferable to performing WSGR which releases the excess carbon as CO2. The integrated processes herein therefore provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming.

  • Patent number: 10597301
    Abstract: A high-concentration ammonia production method includes: synthesizing ammonia through electrolysis using water and nitrogen as raw materials; subjecting a resultant generation gas to treatment using an ammonia separation membrane or an ammonia PSA to separate the generation gas into high-concentration ammonia and a residual gas; recycling the residual gas as a nitrogen gas raw material of an ammonia synthesis reactor, and liquefying the high-concentration ammonia recovered through the ammonia separation membrane or the ammonia PSA; and subjecting an unliquefied gas separated from liquefied ammonia to the treatment using the ammonia separation membrane or the ammonia PSA again. According to the present disclosure, ammonia is synthesized by adopting an electrolysis method in which the synthesized ammonia substantially does not contain hydrogen, in combination with ammonia separation and recovery treatment using membrane separation or PSA.

  • Patent number: 10589994
    Abstract: A burner for producing synthesis gas by partial oxidation of liquid or gaseous, carbon-containing fuels in the presence of an oxygen-containing oxidant and a moderator, which burner can be operated uncooled, i.e. without a fluid coolant being passed through the burner, is proposed. Steam or carbon dioxide or else mixtures of these materials are used as moderator. This is achieved by the feed channels being configured so that mixing of the fuel, the moderator and the oxidant occurs only outside the burner.
