Abstract

Promising of high-temperature devices is the reactors with electrothermal fluidized bed. One of such reactors was developed at the Gas Institute of NAS of Ukraine. It is the laboratory reactor applying circular electrothermal fluidized bed as the external heating element. Pyrolysis of mixture of hydrocarbon gases on the basis of propane was carried out in this reactor. The purpose of this process is to obtain quartz sand encapsulated with pyrolytic carbon, which is used as the model of microspherical nuclear fuel (coated particle fuel). Besides, this material is planned o be used for further carbothermic reduction of silicon. The article presents: the scheme of the reactor and its operational principle, process flow diagram, the experimental result, the calculations of the thermal characteristics, the basic consumption parameters of the reactor. The efficiency of the reactor while carrying out the pyrolysis of mixture of hydrocarbon gases on the basis of propane. Thermal processing of materials that do not conduct the current (dielectric materials) is one of the possible kinds of application of developed reactor. Bibl. 10, Fig. 5, Table 1.
