  • Patent number: 10639586
    Abstract: A method and an integrated system for reducing CO2 emissions in industrial processes. The method and integrated system (100) capture carbon dioxide (CO2) gas from a first gas stream (104) with a chemical absorbent to produce a second gas stream (106) having a higher concentration of carbon monoxide (CO) gas and a lower concentration of CO2 gas as compared to first gas stream. The CO gas in the second gas stream is used to produce C5 to C20 hydrocarbons in an exothermic reaction (108) with hydrogen (H2) gas (138). At least a portion of the heat generated in the exothermic reaction is used to regenerate the chemical absorbent with the liberation of the CO2 gas (128) captured from the first gas stream. Heat captured during the exothermic reaction can, optionally, first be used to generate electricity, wherein the heat remaining after generating electricity is used to thermally regenerate the chemical absorbent.

  • Patent number: 9133075
    Abstract: This invention relates to the production of liquid fuels from coal and natural gas and, more specifically, to a new process that combines Fischer-Tropsch synthesis (FTS) with catalytic dehydrogenation (CDH) and methane injection (MI) into the CDH reactor (FTS-CDH-MI) to eliminate all carbon dioxide emissions during the production of liquid fuels. The additional methane for the FTS-CDH-MI process can be derived from natural gas produced by hydro-fracking. The addition of methane in the CDH process eliminates the need for the standard water-gas shift (WGS) reaction to the syngas, which is used to increase the hydrogen (H2) of the syngas in FTS. This eliminates the use of water in the process and eliminates entirely the production of CO2. In addition to producing the H2 needed for FTS, this process (FTS-CDH) converts the C in these gases into multi-walled carbon nanotubes (MWCNT).

  • Publication number: 20150119478
    Abstract: Gas-to-liquids processes for treating natural gas, including the steps of subjecting the natural gas to expansion through a flow restrictor so as to undergo cooling through the Joule Thomson effect. The processes then separate the resulting liquids from the remaining natural gas and processing the natural gas to form a synthesis gas. The synthesis gas is subjected to Fischer-Tropsch synthesis and the output from the Fischer-Tropsch synthesis is separated into a hydrocarbon product and an aqueous phase and the aqueous phase is steam stripped to extract the oxygenates which are then injected into the natural gas stream upstream of the flow restrictor.

  • Patent number: 9011814
    Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

  • Publication number: 20150080482
    Abstract: The invention relates to a process for increasing the carbon monoxide content of a feed gas mixture comprising carbon dioxide, hydrogen and carbon monoxide via a catalytic reversed water gas shift reaction, comprising the steps of (1) heating the feed gas mixture having an initial feed temperature of at most 350° C. in a first zone to a temperature within a reaction temperature range in the presence of a first catalyst; and (2) contacting the heated feed gas in a second zone within the reaction temperature range with a second catalyst. This process shows relatively high conversion of carbon dioxide, and virtually no methane or coke is being formed, allowing stable operation.

  • Publication number: 20150073062
    Abstract: Techniques, systems and material are disclosed for thermochemical regeneration of biomass into renewable engineered fuel, storage of the renewable engineered fuel, respeciation of the renewable engineered fuel and transport. In one aspect, a method includes generating low density hydrogen fuel from biomass dissociation at a first location of a low elevation. The low density hydrogen fuel is self-transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A high density hydrogen carrier is generated at the second location of higher elevation by reacting the low density hydrogen fuel with at least one of a carbon donor, a nitrogen donor and an oxygen donor harvested from industrial waste. The high density hydrogen carrier is delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy.

  • Patent number: 8969422
    Abstract: A gasification-liquefaction disposal method, system and equipment for MSW are disclosed. The method involves the MSW pretreatment of dehydrating and separating, thus reducing water and inorganic substance content of the waste. Then, the MSW is introduced into a plasma gasifier (23) by a carbon dioxide air-sealed feeding device (13) and gasified therein to obtain hydrogen-rich syngas. The hydrogen-rich syngas is then cooled, deacidified, dedusted and separated to obtain carbon dioxide. Then, the hydrogen-rich syngas is catalyzed to produce methanol product in a methanol synthesis reactor (52). The separated carbon dioxide is sent back to a carbonation reaction chamber (2007) of a gasification system to perform carbonation reaction with calcium oxide, thereby releasing heat to provide assistant heat energy for gasification and avoiding greenhouse gas from being discharged into environment.
