  • Patent number: 8852539
    Abstract: A second stage Fischer-Tropsch reaction system to enhance a conversion ratio of a synthetic gas, includes, at least one first reactor that uses a Fe catalyst, receives a first synthetic gas extracted from a coal, biomass or natural gas, and reacts the first synthetic gas with the Fe catalyst to obtain a synthetic fuel, and a second reactor that uses a Fe.Co or Co catalyst, receives a second synthetic gas discharged from the first reactors after reaction, and reacts the second synthetic gas with the Fe.Co or Co catalyst to obtain a synthetic fuel.

  • Publication number: 20130274508
    Abstract: The present disclosure relates to a single shell open interstage reactor (“SSOI”). The SSOI comprises a first reaction stage, an interstage heat exchanger, an open interstage region, and a second reaction stage. The SSOI may be configured for upflow or downflow operation. Further, the open interstage region of the SSOI may comprise a supplemental oxidant feed. When the open interstage region comprises a supplemental oxidant feed, the SSOI may further comprise a supplemental oxidant mixing assembly. Processes for producing acrylic acid through the oxidation of propylene are also disclosed.

  • Publication number: 20130102821
    Abstract: Process and systems for alkane bromination and, in one or more embodiments, to separate, parallel methane and higher alkanes bromination in a bromine-based process. An embodiment discloses a bromine-based process for converting alkanes to liquid hydrocarbons that includes alkanes bromination, the process comprising: brominating a methane stream comprising methane and having less than about 2 mol % of ethane to form methane bromination products comprising brominated methane and a first fraction of hydrogen bromide; separately brominating a C2+ alkane stream comprising an alkane having 2 or more carbon atoms to form C2+ methane bromination products comprising brominated alkanes having 2 or more carbon atoms and a second fraction of hydrogen bromide; and catalytically reacting at least a portion of the brominated methane and the brominated alkanes to form higher molecular hydrocarbons.

  • Patent number: 8128894
    Abstract: The present disclosure provides a gas reaction device. Reactions are happened on a fixed bed and/or a slurry bed in four reaction states. Thus, by using the four reaction states, reactions are thoroughly completed with the same catalyst. Or, different reactions are completed with different catalysts for different purposes.

  • Publication number: 20100303692
    Abstract: A method, apparatus, and system for a solar-driven chemical plant are disclosed. Some embodiments may include a solar thermal receiver to absorb concentrated solar energy from an array of heliostats and a solar-driven chemical reactor. This chemical reactor may have multiple reactor tubes, in which particles of biomass may be gasified in the presence of a carrier gas in a gasification reaction to produce hydrogen and carbon monoxide products. High heat transfer rates of the walls and tubes may allow the particles of biomass to achieve a high enough temperature necessary for substantial tar destruction and complete gasification of greater than 90 percent of the biomass particles into reaction products including hydrogen and carbon monoxide gas in a very short residence time between a range of 0.01 and 5 seconds.
