    摘要: A downdraft gasifier (1) has an oxidant inlet (3), a biomass injector (2), a grate (9), a gas exit port (7), and an ash removal system (11). A sensor (10) maintains the height of the bed and a rotating paddle (5) maintains the top of the bed (4) at an even height. The grate arrangement (9) is preferably a sliding grate arrangement which actively moves ash material through the grate. An in-bed oxidant distributor (6) injects oxidant within the bed.

    摘要: This invention relates to the production of hydrogen-rich gas by the partial oxidation of a saturated gaseous hydrocarbonaceous fuel or a mixture of saturated gaseous hydrocarbonaceous fuel and a liquid hydrocabonaceous fuel in a gas generator. In the process, a saturated gaseous hydrocarbonaceous fuel from a subsequent fuel gas saturator is preheated by indirect heat exchange with a portion of shifted process gas stream from a catalytic water-gas direct shift conversion zone and reacted in said partial oxidation gas generator. The process gas stream from the noncatalytic partial oxidation gas generator is quench cooled and scrubbed with water and preheated by indirect heat exchange with a second portion of the process gas stream from the shift conversion zone prior to catalytically reacting the CO and H.sub.2 O in the process gas stream in the shift conversion zone to increase its H.sub.2 content. The shifted process gas stream is cooled and dewatered to produce shift condensate which is used to saturate the aforesaid preheated gaseous hydrocarbonaceous fuel feedstream to the partial oxidation gas generator.

    摘要: According to the present invention, the ignition, combustion and explosion of hydrogen-air mixtures are dependent primarily on the presence of active intermediates (free atomic hydrogen, atomic oxygen and hydroxyl radicals) that serve as chain carriers and enable the propagation of reaction chains. These active intermediates rather than thermal energy are of primary importance to the oxidation process. The proposed inhibitor molecules capture these active intermediates. This capturing in turn suppresses the reaction chains. As a result, the oxidation of hydrogen in air, including the transition to combustion, the intensity of combustion, the transition from combustion to explosion and the intensity of explosion vary inversely with the inhibitor content. Even when the amount of inhibitor is too small to prevent ignition, a greater ignition source is needed and the intensity of combustion is reduced. The transition from combustion to explosion is also made more difficult or prevented. Moreover, the intensity of explosion, if it occurs, will be decreased. Consequently, the choice of inhibitor and control of its concentration in a hydrogen-air mixture provides for a method of regulating (1) the transition to combustion, (2) the intensity of combustion, (3) the transition from combustion to explosion and (4) the intensity of explosion. The proposed inhibitors include saturated or unsaturated hydrocarbons with one to eight carbon atoms that have a normal structure, an isostructure or a cyclical structure, including aromatics, and mixtures of such hydrocarbons.

    摘要: Oil shale containing relatively large quantities of alkaline carbonate minerals is retorted utilizing superheated water vapor at temperatures of from about 425.degree. C. to about 510.degree. C. Retorting with a sufficient carbon dioxide partial pressure effectively suppresses decomposition of the alkaline carbonates to obtain an environmentally acceptable retorted shale.
