  • Patent number: 10703689
    Abstract: A process for converting a feed stream to C2 to C5 hydrocarbons includes introducing a feed stream of hydrogen and at least one carbon-containing component selected from CO, CO2, and mixtures thereof into a reaction zone at an initial reactor pressure and an initial reactor temperature. The feed stream is contacted to a hybrid catalyst positioned in the reaction zone, and the hybrid catalyst includes a methanol synthesis component and a solid microporous acid material. The pressure within the reaction zone is increased during the contacting of the feed stream to the hybrid catalyst from the initial reactor pressure to a final reactor pressure. A temperature within the reaction zone at any time during the contacting of the feed stream to the hybrid catalyst is within ±20° C. of the initial reactor temperature.

  • 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: 10519087
    Abstract: The present invention provides methods for making propanal in a reaction comprising the oxidative coupling of methane (OCM) and oxygen as a reactant stream in a gas phase reaction, preferably in the presence of water or steam, to form ethylene, ethane, carbon dioxide (CO2), water and syngas (CO and H2) in a first reactor as an ethylene stream, and then forming propanal in a second reactor by feeding to the second reactor the ethylene stream with the syngas from the first reactor in the gas phase and hydroformylating in the presence of a catalyst for a water shift reaction. In the method, the ratio of H2 to CO in the syngas is maintained by either co-feeding steam into the first reactor or the second reactor to generate additional H2 in the syngas, or by forming CO in the second reactor from the water shift reaction by feeding the CO2 from the ethylene stream into the second reactor.

  • Patent number: 10329209
    Abstract: A process for preparing C2 and C3 olefins comprises contacting a feedstream including hydrogen, carbon monoxide, and a bifunctional catalyst in a reaction under certain specified conditions. The catalyst includes as components (1) chromium oxide and zinc oxide mixed metal oxides, and (2) a SAPO-34 molecular sieve. The resulting product of the reaction is relatively high in the target lower olefins and relatively low in less desirable products, including C2 and C3 paraffins, C4+ hydrocarbons, oxygenates, and methane, thereby reducing or eliminating the need for certain previously common and costly separations. The bifunctional catalyst as used in the inventive process also offers improvements in catalyst life in comparison with some methanol-to-olefins catalysts. The process may be carried out as a single unit operation.

  • Patent number: 9073804
    Abstract: Conversion of synthesis gas to propylene is enhanced via a stepped process wherein a Fischer-Tropsch reaction is first carried out, followed by recovery of propylene produced thereby and then use of product ethylene and unreacted syngas in a hydroformylation reaction to produce propanol, which is then dehydrated to form additional propylene. The process enables significant enhancement of propylene yield that is efficient and makes use of ethylene that is a byproduct of Fischer-Tropsch processes that are employed primarily for production of higher olefins, such as hexene and octene. Thus, it can be carried out in conjunction with already on-line Fischer-Tropsch facilities.
