Patent number: 10639586Abstract: 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.Type: GrantFiled: November 14, 2016Date of Patent: May 5, 2020Assignee: Dow Global Technologies LLCInventors: Thomas Davidian, Steven Corthals, Cornelis Biesheuvel, Matthijs Ruitenbeek, Andrzej Malek, Peter E.

Patent number: 10519087Abstract: 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.Type: GrantFiled: June 13, 2017Date of Patent: December 31, 2019Assignee: Dow Global Technologies LLCInventors: Steven L.
