Abstract: The machinery and methods disclosed herein are based on the use of a specialized extruder configured to continuously convey and plasticize/moltenize selected lignocellulosic biomass and/or waste plastic materials into a novel variable volume tubular reactor, wherein the plasticized/moltenized material undergoes reaction with circumferentially injected supercritical water—thereby yielding valuable simple sugar solutions and/or liquid hydrocarbon mixtures (e.g., “neodiesel”), both of which are key chemical commodity products. The reaction time may be adjusted by changing the reactor volume. The machinery includes four zones: (1) a feedstock conveyance and plasticization/moltenization zone; (2) a steam generation and manifold distribution zone; (3) a central supercritical water reaction zone; and (4) a pressure let-down and reaction product separation zone. The machinery and methods minimize water usage—thereby enabling the economic utilization of abundant biomass and waste plastics as viable renewable feedstocks for subsequent conversion into alternative liquid transportation fuels and valuable green-chemical products.

Abstract: The present invention describes a method and device for pretreatment of organic material, more specific bio mass, for energy conversion, where said method comprises a first preheating step with a preheating vessel (4), a hydrolysis step with a hydrolysis reactor (5) and a pressure reducing step with a pressure reduction vessel (6), where the transfer of said organic material from the preheating vessel (4) to the hydrolysis rector (5) is effected by gravity and by creating a vacuum in the reactor (5). This method results in a very fast transfer of material from the preheating vessel (4) to the reactor (5). In addition, the filling volume of the reactor (5) is being controlled by a high frequency pressure sensor and supply of steam (3A) to the top of the reactor in order to provide the necessary head space. The invention also describes a device for performing said method.

Abstract: Apparatus and methods are provided for converting methane in a feed stream to acetylene. A hydrocarbon stream is introduced into a supersonic reactor and pyrolyzed to convert at least a portion of the methane to acetylene. The reactor effluent stream may be treated to convert acetylene to another hydrocarbon process.
