摘要： Systems and methods are provided for conversion of methane and/or other hydrocarbons to hydrogen by pyrolysis while reducing or minimizing production of carbon oxides. The conversion of hydrocarbons to hydrogen is performed in one or more pyrolysis or conversion reactors that contain a plurality of sequential fluidized beds. The fluidized beds are arranged so that the coke particles forming the fluidized bed move in a counter-current direction relative to the gas phase flow of feed (e.g., methane) and/or product (H2) in the fluidized beds. By using a plurality of sequential fluidized beds, the heat transfer and management benefits of fluidized beds can be realized while also at least partially achieving the improved reaction rates that are associated with a plug flow or moving bed reactor.

摘要： A method for producing a hydrogen gaseous fuel from kinetic and/or potential energy recovered from a vehicle powered by a four stroke Diesel engine fitted with a Jacobs engine brake during a deceleration stage. Such a method comprises the following steps: a) providing a preheated steam flow; b) providing a gas flow from at least one chemical species used as preheated carbon and hydrogen source; c) mixing the gas flow from at least one chemical species used as carbon and hydrogen source from step a) with the steam flow from step b); d) reacting the mixture from step c) in the catalytic bed of a reforming reactor, heated by high temperature air from the compression stage of the Diesel engine acting as engine brake upon deceleration, producing an outlet synthesis gas flow which contains hydrogen; e) causing water to condense in the outlet synthesis gas flow which contains hydrogen, producing a water-free synthesis gas flow, and f) storing the synthesis gas flow obtained at step e) in a reservoir for its subsequent use during an acceleration stage of the vehicle. A system useful to implement the method for recovering kinetic and/or potential energy from a vehicle powered by a four stroke Diesel engine fitted with a Jacobs engine brake during a deceleration stage.

摘要： The invention relates to a process and an apparatus for gasifying liquid and/or fine-grain solid gasification substances and/or for reforming a gas, using a gasification agent, in a reactor (1). In the process the process heat is supplied by heat carrier particles which are heated within a substantially closed circuit in a heater (5) by combustion gases which are produced in a combustion chamber (3), and passed through the reactor (1) in counter-flow relationship with the gasification substance or the gas to be reformed and the gasification agent, and then returned to the heater (5) for renewed heating. In accordance with the invention the particles and the combustion gas form a fluidized bed above at least one grid (34, 34a, 34b, 34c, 34d, 34e) arranged in the heater (5). The particles flow out of the heater (5) into the adjoining combustion chamber (3) in which they form a fluidized bed with the combustion gas and pass by way of a flow transfer pipe (7, 7') out of the combustion chamber (3) into an upper region of the reactor (1). The throughput of particles through the flow transfer pipe (7, 7') forms a seal which prevents a throughflow of product gas which is generated in the reactor (1). The particles form one or more fluidized beds in the reactor (1) with the gasification substance and/or the gas to be reformed.

摘要： An improved grid plate flow distributor assembly for use in a pressurized catalytic reactor in which gas and liquid materials flow uniformly upwardly through the grid into the reactor ebullated catalyst bed. The grid plate assembly contains multiple vertical flow tubes each covered at its upper end by a cap which is spaced outwardly from the tube upper end and preferably has tapered sides. The cap can have any horizontal cross-sectional shape, such as circular, polygonal, rectangular or triangular. If desired, a horizontal elongated cap can be used which covers at least two adjacent vertical flow tubes. Such elongated caps can be provided as concentric circular shapes above the grid plate. Also, if desired, a thermocouple can be provided extending upwardly above the cap, such as through selected caps to monitor the temperature distribution of the ebullated bed above the grid plate assembly.

摘要： Carbon-containing materials are gasified to produce high purity carbon monoxide in a three zone unified system (oxidizer, reducer and gasifier) using a metal oxide as the oxygen and heat source for the gasification with carbon monoxide. Carbon monoxide contacts the metal oxide prior to the gasification to release the oxygen and convert the carbon monoxide to carbon dioxide as the gasification medium.

摘要： An enclosed path 3, Fig. 6, terminating in a downwardly-facing converging entrance 4 within a chamber 1 is employed to convey a fine-grained mixture of salts of benzene sulphonic acids and alkali or alkaline earth hydroxides from a fluidized bed in said chamber to a bed in another chamber 2, maintained in fluidized condition by a stream of steam in parallel with that in the first chamber, the bed in the first chamber being maintained at a level above the lower edge of said converging entrance. The reaction between the components manner and phenols are produced. Specifications 755,959, [Group XII], and 762,062, [Group XXX], are referred to.ALSO:An enclosed path (3) terminating in a downwardly-facing converging entrance (4) within a chamber (1) is employed to convey material, e.g. a catalyst in a hydrocarbon cracking process from a bed of material in said chamber to a bed in another chamber (2) said beds being maintained in fluidized condition by a continuously feeding a steady upward current of gas into said chambers and the bed in the first chamber being maintained at a level above the lower edge of said converging entrance. The numerals relate to Fig. 6. The apparatus may also be used for the dehydrogenation, hydrogenation, aromatization and alkylation of hydrocarbons or their synthesis from carbon monoxide or hydrogen, or in roasting ores or calcining calcium carbonate. The wider end of the converging entrance is preferably given a short cylindrical section 26, preferred sizes and proportions are indicated. More than one conduit may if desired be employed, as may a series of chambers containing fluidized beds arranged adjacently if desired, e.g. as described in Specification 755,959. In the latter case, heating or cooling pipes or other passages for a heat transferring medium may be arranged in the side walls of the chambers. If desired the device to separate the gas from the solid, e.g. a dust collector or cyclone may be included in the conduit; this device may be situated in either chamber or between the chambers, and the gas outlet thereof may be arranged to open into either chamber, so that if desired it is possible to keep the gases in the chambers, which may be different, separate: thus a catalyst could be passed through the chambers in series and alternately be contacted with the reactant gases, and regenerated. If a series of chambers (17) is used, they may be arranged in series as indicated in Fig. 5, on a grid with preparations 25 through which the fluidizing gas passes, and surrounded by a cylinder 16 in which a fluidized bed is maintained, solids entering the first chamber by conduit 5 and finally emerging from separator 18. The bed in the surrounding cylinder may be used to regulate the temperature of the reaction, the solid or gas being simultaneously pre-heated. A fluidized bed of solid material may alternatively be kept permanently in said cylinder and not discharged. Such an apparatus may be used, e.g. for carbonization of coal (in chambers 17, coke being fluidized in the cylinder 16) or an endothermic reaction (e.g. cracking of hydrocarbons) in conjunction with an exothermic reaction (e.g. the regeneration of the cracking catalyst). Specification 762,062 [Group XXX] also is referred to.
