摘要： A fluidized bed apparatus for batch-by-batch or continuous process control is provided that allows the processes in the fluidization region to be influenced as desired, especially in terms of material movement and dwell time. The fluidized bed apparatus is formed from at least two processing regions and the processing regions are connected to each other by overflow channels. The first processing region is provided with a solids inlet and the last processing region is provided with a solids outlet. For influencing the dwell time, the material to be treated is supplied to at least two processing regions one after the other and flows through these regions, wherein the material transport direction is a cross flow relative to the flow of the fluidization means.

摘要： Methanol supplied as a raw fuel is mixed with water, vaporized in an evaporator 24, and supplied to a reformer 22 as a raw fuel gas. The reformer 22 also receives a supply of the compressed air from an air tank 36. The raw fuel gas is mixed with the compressed air in the reformer 22. An oxidation reaction of methanol supplied as the raw fuel proceeds in the reformer 22 to generate hydrogen and carbon dioxide, while a steam reforming reaction of methanol simultaneously proceeds in the reformer 22 to generate hydrogen and carbon dioxide. The amount of heat required for the endothermic reforming reaction can be supplied by the oxidation reaction of methanol. No external heat source is accordingly required in the reformer 22 to supply the heat required for the reforming reaction.

摘要： A fluid bed reactor is provided having a grid baffle structure to provide increased theoretical stages within the reactor to enable the reactor to be used for time/temperature dependent reactions requiring a number of mixing stages and/or an increased particle residence time. The preferred baffle structure comprises a plurality of staggered first and second vertical members extending partly across the reactor from opposed sides of the reactor which form a path for the feed to travel therethrough from the inlet to the outlet of the reactor with the vertical members having vertical cross-members, preferably shorter than the vertical members, extending completely between adjacent vertical members and/or partly in the space between the members to form reaction stage sections whereby feed entering the reactor moves in a serpentine path and/or a sequential underflow and/or overflow path through the reaction stage sections of the baffle from the inlet of the reactor to the reactor outlet.

摘要： A reversibly deactivated, particulate catalyst in a hydrocarbon synthesis slurry is rejuvenated by circulating the slurry from a slurry body through (i) a gas disengaging zone to remove gas bubbles from the slurry and increase its density, (iii) a downcomer which feeds the gas reduced, dense slurry into the bottom of a rejuvenating tube and applies a positive hydrostatic pressure to the tube, (iii) a catalyst rejuvenation zone in which a catalyst rejuvenating gas, which also acts as a lift gas, contacts the catalyst in slurry to form a catalyst rejuvenated slurry and, (iv) back into the slurry body. Removing gas bubbles prior to rejuvenation improves the rejuvenation efficiency and the downcomer reduces the amount of rejuvenation gas required to maintain slurry circulation through the tube.

摘要： Distributor device comprises at least one lower and/or one upper stationary distributor device for distribution of fuel in the form of gas and particles in a fluidized bed and is arranged above fuel feed nozzles in the bed, or at or above the upper limit of the bed. The task of the distributor device is to spread fuel, rising upwards in the bed, more evenly over a large area in the bed and to create turbulence above the bed. This is achieved by designing the distributor device with a mid-portion and upwardly-inclined wing-like members or the cone to bring about even distribution of fuel by forcing the fuel to follow an outwardly-directed horizontal or obliquely upwardly-rising flow of fuel.

摘要： A fluidized catalytic cracking process and apparatus operates with a single or multi- stage refluxed catalyst stripper. Recycle, or reflux, of stripped catalyst to the stripping zone improves stripping. Preferably, a two stage hot stripper is used. Addition of regenerated catalyst to spent catalyst from the reactor heats spent catalyst in a first stripping stage, which preferably uses stripping steam. Catalyst from the first stripping stage passes up through a second stage stripping zone with a heat removal means, e.g., a stab-in tube bundle. Steam or flue gas fluidizes catalyst, improves heat transfer and strips the catalyst. Some catalyst from the second stage stripper is preferably recycled to the inlet to the first stripping stage. Additional hot regenerated catalyst may be added downstream of the first catalyst stage to heat the second stripping stage, added to catalyst removed from the primary stripping zone which is sent to the regeneration zone.

摘要： An arrangement is provided for locating internal cooling coils in an FCC regeneration zone that allows control of the cooling coil wall temperature independently of the regeneration zone operation and the circulation rate of cooling fluid through the cooling conduits. The cooling conduits are located within a vessel that contains the combustion section for an FCC regeneration zone. The cooling coils are in a chamber that is closed to catalyst transfer across all of its boundaries except its top. The level of hot regenerated catalyst within the regeneration zone is maintained above the top of the cooling chamber. The addition of flue gas to a lower portion of the cooling chamber provides a random exchange of catalyst particles between the layer of the catalyst bed above the chamber and catalyst within the chamber. By controlling the rate of fluidizing gas addition to the chamber, the rate of exchange of hot catalyst between the chamber and the bed is also controlled. Throttling back the flow of fluidizing gas to the chamber reduces the amount of heat transfer from the catalyst, thereby lowering the wall temperature of the cooling conduits for a constant circulation rate of cooling fluid. The cooling chamber is arranged such that a stagnant layer of catalyst surrounds the cooling coils when the flow of fluidizing gas is cut off. In this way, the cooling conduits can be maintained indefinitely within an operating regeneration zone without the circulation of cooling fluid. Such an operation is particularly advantageous during start-up when the regeneration zone is being heated to initiate the combustion of coke in the regeneration operation.

摘要翻译： 提供了一种用于将内部冷却盘管定位在FCC再生区中的装置，其允许独立于再生区操作控制冷却盘管壁温度和通过冷却管道的冷却流体的循环速率。 冷却管道位于容纳有用于FCC再生区的燃烧部分的容器内。 冷却盘管位于除了其顶部之外的除了其所有边界之外的催化剂转移闭合的室中。 再生区内热再生催化剂的水平保持在冷却室顶部的上方。 将烟道气添加到冷却室的下部提供催化剂颗粒在室之上的催化剂层和室内的催化剂之间的随机交换。 通过控制加入到室中的流化气体的速率，也控制了室和床之间的热催化剂的交换速率。 将流化气体流向腔室的回流减少了从催化剂传热的量，从而降低冷却管道的壁温，使冷却液的循环速率恒定。 冷却室被布置成使得当流化气体的流动被切断时，催化剂的停滞层围绕冷却盘管。 以这种方式，冷却管道可以无限期地保持在操作再生区域内，而不会冷却流体的循环。 这种操作在启动期间特别有利，当再生区被加热以在再生操作中引发焦炭的燃烧时。

摘要： In a hot gas generating apparatus coal is fed to a first gasifying fluidized bed wherein it is partially gasified to generate a combustible gas and char. The char is circulated to a second combustion fluidized bed for burning in the presence of excess air. The combustible gas is mixed with the oxygen rich gases from the second bed and burnt to give a hot gas product.
