Description

This invention relates to a removal device and method for removal in a reaction apparatus. There are reaction apparatuses that produce desired products by applying a predetermined atmosphere to a granular material. For example, Patent Document 1 discloses a reaction apparatus comprising a screw-feeder body serving as a pressure reaction vessel, a catalyst supply unit for introducing a catalyst into the screw-feeder body, and a lower hydrocarbon supply unit for introducing lower hydrocarbons into the screw-feeder body. This reactor comprises a screw for transporting nanocarbon produced by the thermal decomposition of a catalyst and lower hydrocarbons, a solid discharge section for delivering the catalyst and nanocarbon transported by the screw, and a gas discharge section for delivering the generated hydrogen outside the feeder body. In this reactor, the nanocarbon that grows over time is continuously discharged from the reaction vessel along with the spent catalyst, and the same amount of unused catalyst is supplied to maintain a continuous reaction.

Figure 1 is a diagram illustrating an example of the configuration of a reaction apparatus 10 to which the extraction device of this embodiment is applied. Figure 1 is a side view of the reaction apparatus 10, and a portion of it has been cut out for ease of understanding. The reaction apparatus 10 is a device for producing products by, for example, applying predetermined physical stimuli or other conditions to a material to be processed. The type and state of the material are not particularly limited, but they may be inorganic substances such as metal oxides or metal sulfides containing lithium as one component, or organic substances such as hydrocarbons. The material may be a solid such as a powder or granules, or a fluid such as a liquid or gas. Furthermore, the material may pass through intermediates during the process of transformation into the product. The form and state of the intermediates are not particularly limited, but the intermediates may be, for example, the products of each reaction when two or more reactions are carried out stepwise. In that case, the intermediates may be, for example, an anhydrous compound produced by heating a hydrated compound. Alternatively, the intermediates may be calcined bodies in which at least a portion of the material has undergone grain growth or calcination. The intermediates may also be in a state where at least a portion of the material has been liquefied or vaporized. The intermediates may also be in forms or states oth
