摘要： The present disclosure refers to systems and methods for the production, storage, and transportation of hydrogen. In a representative embodiment a reactor system comprises a fluidized bed combustor configured for reduced metal oxide oxidation and heat generation without significant greenhouse gas emission and/or with readily capturable emissions. The reactor system also comprises a liquid organic hydrogen carrier dehydrogenation reactor. The fluidized bed combustor is operatively coupled to the liquid organic hydrogen carrier dehydrogenation reactor. Advantageously, at least a portion of heat generated by the fluidized bed combustor may be transferred to the liquid organic hydrogen carrier dehydrogenation reactor. In this manner hydrogen production and transportation is both energy efficient, low carbon intensity and cost-effective.

摘要： A method of carrying out direct thermal decomposition of a hydrocarbon compound into carbon and hydrogen comprises: introducing a gaseous feed stream comprising at least one hydrocarbon compound into a reactor; and removing at least hydrogen gas and particulate carbon formed by thermal decomposition from the reactor. The method includes providing in the reactor a layer permeable to the particulate carbon and comprising loose particles other than the particulate carbon in a gas phase and passing the gaseous feed stream through the layer. The loose particles other than the particulate carbon comprise particles comprising a catalyst on a carrier. The method includes removing at least part of the layer from the reactor, separating constituents of the removed part, the constituents including some of the particles comprising a catalyst on a carrier, and returning the separated particles comprising a catalyst on a carrier to the layer.

摘要： A method of operating a mass spectrometer vacuum interface, the vacuum interface comprising an evacuated expansion chamber downstream of a plasma ion source at atmospheric or relatively high pressure, the expansion chamber having a first aperture that interfaces with the plasma ion source to form an expanding plasma downstream of the first aperture and a second aperture downstream of the first aperture from the plasma for skimming the expanding plasma to form a skimmed expanding plasma; wherein the expansion chamber is pumped by an interface vacuum pump to provide an interface pressure in the chamber; the method comprising using a controller to automatically, or according to user input, control the throughput of the interface vacuum pump to control the interface pressure dependent on one or more operating modes of the spectrometer. A pressure gauge can be located in the expansion chamber and a feedback loop provided between the pressure gauge and controller.

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： Process for the production of synthesis gas and higher hydrocarbons in which a saturated hydrocarbon and an oxygen containing gas having a ratio of hydrocarbon to oxygen of greater than the stoichiometric ratio for complete combustion are introduced into a bed of an inert particulate material. The upward flow rate of the hydrocarbon/oxygen containing gas stream is sufficient to fluidize or to produce a spouting action of the bed material, whereby the particulate material is thrown up above the bed surface and subsequently falls back into the bed. The hydrocarbon and oxygen containing gas are ignited reacted together, and the products of the reaction withdrawn.

摘要： A process for fluidized catalytic cracking of heavy oils and production of hydrogen is described, comprising contacting steam and heavy oils with fluidized catalyst particles containing reduced iron at high temperatures, wherein a fluidized bed is formed such that the catalyst particles are fed from the bottom and withdrawn from the top of the fluidized bed and the fluidized bed is provided with a means for retarding the mixing rate of the catalyst particles in the vertical direction, to thereby generate a temperature difference between zones of the fluidized bed above and below said means, and use the upper zone for cracking of heavy oils and the lower zone for production of hydrogen. Catalyst particles withdrawn from the fluidized bed may be regenerated and recycled. Thus, light oils and hydrogen can be produced in high yields.

摘要： Waste water formed in the gasification of coal and containing ammonia, H.sub.2 S, and phenolic compounds is treated to remove H.sub.2 S and a substantial proportion of its ammonia, while leaving sufficient ammonia in the water to maintain a pH of at least 8 (such as up to about 10.5, preferably about 8.5 to 9), the ammoniacal water is then flashed into a stream of superheated steam being fed to gasification zone. At the high temperatures in the gasification zone the organic impurities are decomposed.
