  • Publication number: 20250084327
    Abstract: Described are new processes for making sustainable jet fuels and components thereof, based upon generating bio-ethylene by dehydration of biomass ethanol or a bio-syngas ethanol, and subsequently employing a tailored selection of oligomerization, cyclization, and hydrogenation reactions to generate each class of compounds which can be used as components in a sustainable aviation fuel. For example bio-ethylene oligomerization can provide olefin oligomers which can be hydrogenated to linear and branched paraffins, these paraffins can be cyclized to form bio-sourced aromatic compounds which subsequently can be hydrogenated to form cycloparaffins or naphthenes. These compounds can be blended to provide sustainable products in the kerosene jet fuel range (C8-C16) or wide-cut jet fuel range (C5-C15 or C4-C16).

  • Publication number: 20240304844
    Abstract: Processes and systems that utilize a fuel cell for carbon capture from a petrochemical stream that contains hydrogen and methane. The petrochemical stream can be the tail gas of a hydrocarbon cracking system, or any other petrochemical stream containing hydrogen and methane. The petrochemical stream can be separated into a hydrogen product stream and a methane product stream, before sending the methane product stream to the fuel cell. The fuel cell converts methane to carbon dioxide and hydrogen to water, while generating electricity that can be used to power equipment.

  • Patent number: 12077616
    Abstract: Processes for producing ethylene-based polymers and oligomers from ethanol include the steps of contacting the ethanol and a catalyst to produce a reaction mixture containing ethylene, wherein a first portion of the ethanol is derived from a biomass and a second portion of the ethanol is derived from a plastic, a mixed solid waste stream, or a combination thereof, separating at least a portion of the ethylene from the reaction mixture, and contacting ethylene with a suitable polymerization or oligomerization catalyst composition to produce the ethylene polymer or ethylene oligomers. A related process for producing ethylene-based polymers and oligomers uses a first ethylene feed derived from ethanol and a second ethylene feed derived from a plastic, a mixed solid waste stream, or a combination thereof.

  • Publication number: 20240109774
    Abstract: A hydrogen-rich hydrocarbon fuel gas can be separated into a methane fuel stream and a hydrogen product stream. The methane fuel stream can be fed to a methane fuel fired furnace, combustion of the methane fuel stream can produce a carbon-dioxide-rich flue gas, and a carbon capture process can be performed on the carbon-dioxide-rich flue gas. The hydrogen product stream can be fed to a hydrogen fired furnace or elsewhere. Combustion of the hydrogen product stream in a hydrogen fired furnace can generate a flue gas the is low in carbon dioxide. Electrolysis of water obtained from the hydrogen fired furnace flue gas can produce hydrogen for a desired use, such as fuel for the hydrogen fired furnace, and can produce oxygen for enriching the fuel gas fed to the methane fuel fired furnace.
