    Abstract: A continuously flowing fluid is processed by being fed to the top of a hydraulic downdraft column (17) which is of a height such that the pressure at the bottom thereof will approximately be at the pressure necessary to create supercritical water conditions. The fluid is conducted to the bottom of the column (17) and received in a reaction chamber (21) in which the majority of the fluid is recirculated around an annular baffle plate (24). The material in the reaction chamber (21) is heated to a temperature above that necessary to create supercritical water conditions by an independent reaction taking place in a heating chamber (32). The result is that the fluid will undergo chemical reactions at the supercritical temperature and pressure range and will be of a lower specific gravity than the unprocessed fluid. The material not being recirculated in the chamber (21) is fed to one of two updraft columns (30, 31), a start-up column (30) used to preheat the material in the downdraft column (17) during initiation of the process, and a second column ( 31) isolated from the downdraft column (17) so as not to transmit any heat thereto during normal operation of the process. The temperature of the fluid in the downdraft column (17) is thereby controlled to prevent decomposition of the material until the fluid enters the reaction chamber (21) at which time it is abruptly brought up to the supercritical water temperature.

    Abstract: An autoclave apparatus comprising an autoclave forming a product-receiving chamber having an inlet port in one end and an outlet port in the opposite end and being, further, formed with an access opening. An electrically heated heat exchanger is formed with a chamber which contains heat storage means and such chamber has an inlet in one end and an outlet in the opposite end. Conduits connect the inlet to the autoclave with the outlet from the heat exchanger and the outlet of the autoclave with the inlet to the heat exchanger. Means is provided for supplying gas to the system whereby such system may be pressurized with the gas and such gas circulated through the autoclave and in heatexchange relationship with the heat storage means to heat such gas to an elevated temperature thereby providing an atmosphere in the product-receiving chamber of the desired temperature and pressure.

    Abstract: The invention relates to a method and apparatus for safely producing hydrogen peroxide by injecting dispersed minute bubbles of hydrogen and oxygen into a rapidly flowing liquid medium. The minute bubbles are surrounded by the liquid medium of sufficient volume for preventing an explosive reaction between the hydrogen and oxygen. The liquid medium is formed of an acidic aqueous solution and a Group VIII metal catalyst. Hydrogen is sparged into the flowing medium for dissolution of the hydrogen in the medium. Oxygen bubbles are reacted with the dissolved hydrogen for producing hydrogen peroxide. Preferably, the liquid medium has a velocity of at least 10 feet per second for providing a bubbly flow regime in the reactor. The invention allows the direct combination of oxygen and hydrogen while preventing propagation of an explosive condition within the reactor. The method and apparatus provide for the safe production of hydrogen peroxide with low manufacturing costs.
