  • Publication number: 20240124377
    Abstract: There are provided systems and methods for using fuel-rich partial oxidation to produce an end product from waste gases, such as flare gas. In an embodiment, the system and method use air-breathing piston engines and turbine engines for the fuel-rich partial oxidation of the flare gas to form synthesis gas, and reactors to convert the synthesis gas into the end product. In an embodiment the end product is methanol.

  • Publication number: 20230279802
    Abstract: There are provided systems and methods for the use of rich limit extenders, and in particular pre-chamber assemblies, for increasing the ability of a spark-ignition engine to operate under fuel-rich conditions. In embodiments the pre-chamber assemblies are combined with spark-ignition engines as a reformer in a gas-to-liquid system for converting a combustible fuel source into synthesis gas. Embodiments of the reformers having pre-chambers provide a synthesis gas product having a H2/CO ratio, with increased H2 concentrations.

  • Patent number: 11692078
    Abstract: A coated fiber for polymer reinforcement is disclosed. The coated fiber comprises a fiber and a coating disposed about said fiber. The fiber has a denier of from about 250 to about 3,000. The coating comprises a branched polyethylene imine. The fiber is present in the coated fiber in an amount of from about 80 to about 99.8 percent by weight and the coating is present in the coated fiber in an amount of from about 0.2 to about 20 percent by weight, with percent by weight based on the total weight of the coated fiber. A method of producing the coated fiber is also disclosed.

  • Patent number: 11624153
    Abstract: A method of increasing the throughput and/or decreasing the energy usage of a pulping process includes the steps of providing a plurality of lignocellulosic chips, providing a refining composition, applying the refining composition to the plurality of lignocellulosic chips, and mechanically refining the plurality of lignocellulosic chips to form pulp. The refining composition includes water and a lubricating additive including the reaction product of a sugar and an alcohol. The step of applying the refining composition to the lignocellulosic chips is conducted less than 5 minutes prior to, or concurrently with, the step of mechanically refining the wood chips to form pulp.

  • Patent number: 11584874
    Abstract: Described herein is an ice melting composition that includes at least one solvent, at least one deicing agent, and at least one additive. Possible additives include ionic liquids, deep eutectic solvents, dispersants and combinations thereof. The composition exhibits an increased saturation point due to the addition of the additives thereby reducing or eliminating precipitation of the deicing agent at low temperatures. Also described herein are methods of melting ice or preventing ice from forming on a surface. The methods include applying the ice melting composition to the surface either before or after ice forms.
