Abstract: The present invention provides a highly effective method of removal of gases from the chemical reactor (01) by use of a suction unit employed near the inlet, outlet or both ends of the chemical reactor. The suction of entrapped air from the reaction mixture helps avoid fluctuation in the temperature or pressure requirement or formation of other by-products in the reaction mixture.

Abstract: An autoclave vacuum system uses two vacuum sources to selectively impart a vacuum. In an exemplary embodiment, the vacuum sources are different types, wherein the first vacuum source is a vacuum pump, and the second source is a Venturi vacuum. The autoclave vacuum system uses a valve system for controlling whether the first and/or second vacuum sources are fluidly coupled to the vacuum enclosure. The valve system allows the autoclave vacuum system to assume a plurality of different configurations chosen such that a constant desired pressure is attained in the autoclave. The valve system may be triggered by a control system configured to recognize and act upon autoclave requirements such as temperature, pressure, duration of use, and number of cycles.

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.
