  • Patent number: 11965134
    Abstract: A process for the production of sustainable aviation fuel (SAF) with low carbon intensity. The jet fuel is produced from the reaction of hydrogen from the electrolysis of water with captured carbon dioxide. The hydrogen and carbon dioxide are reacted to product a stream comprising carbon monoxide. Hydrogen and carbon monoxide are reacted to produce n-alkanes. Alkanes are hydroisomerized to produce sustainable aviation fuel with low carbon intensity.

  • Publication number: 20240093105
    Abstract: Provided herein are systems and methods for controlling the production of negative carbon-intensity liquid hydrocarbons (e.g., for fuels and chemicals). In various aspects, the methods utilize a feedstock having a negative carbon intensity, produce a co-product from the feedstock, sequester a portion of the CO2 derived from the feedstock, or utilize a portion of the O2 in a process that consumes O2 and emits CO2.

  • Patent number: 11026416
    Abstract: A turkey call holder includes an open-top receptacle for receiving a pot call there through such that at least a portion of the pot call resides within the receptacle. Clamping shoes, disposed in opposition to one another within the receptacle, are elastically biased towards one another by at least one elastic member such that the clamping shoes engage opposing sides of a portion of the pot call residing within the receptacle. A flexible strap is coupled to the receptacle for securing the receptacle to a limb of a user.

  • Publication number: 20130287971
    Abstract: A lightweight, arm supported wing creature prop designed to be attached to the user's arm or wrist. The prop is made flexible, or semi-flexible foam designed to be folded into a compact configuration on one arm and then selectively unfolded and displayed on the arm. In one embodiment, the prop includes a wrist wrap with thumb and finger openings. Mounted on the dorsal side wrist wrap is a wing assembly with an intermediate section and two wings that extend laterally on opposite sides of the intermediate section. Also attached to the wrist wrap or to the wing assembly is a tail panel designed to simulate the tail of a wing creature. The wing assembly is made of foam material that sufficiently flexible so the wings may wrap around the user's wrist and held with a strap. In a second embodiment, the wrist wrap is replaced by a strap attached at one end to the wing assembly and extends under the user's wrist or palm and connects with a strut.
