  • Patent number: 11925923
    Abstract: A pulsed compression reactor may include a reactor housing, a spring piston, and a driver piston. The reactor housing may define an interior volume, and may include a first passage and a second passage which lead to the interior volume. The spring piston may be positioned within the interior volume, wherein the spring piston and the reactor housing at least partially define a perimeter of a gas spring buffer chamber within the interior volume. The driver piston may be positioned within the interior volume, wherein the spring piston, the driver piston, and the reactor housing at least partially define a perimeter of a reaction chamber within the interior volume.
    Type: Grant

  • Patent number: 8129436
    Abstract: The present invention provides a method for simplifying manufacture of a mixed alcohol or mixed oxygenate product from synthesis gas. The mixed alcohol or mixed oxygenate product contains ethanol and other oxygenates with two or more carbon atoms per molecule. The method includes stripping a portion of carbon dioxide and inert gases contained in a mixed alcohol synthesis reaction product using a methanol-containing stream, such as one produced as part of the method, as a medium to absorb said carbon dioxide and inert gases and recycling light products and heavy products to one or more of synthesis gas generation, mixed alcohol synthesis and separation of desired mixed alcohol or mixed oxygenate products from other components of a mixed alcohol synthesis stream.
