FIELD: reactors.
SUBSTANCE: invention relates to a reactor used for endothermic high-temperature reactions, for example, for steam reforming of a hydrocarbon-containing feed gas stream (for example, containing methane), for cracking or thermal decomposition of ethane, for pyrolysis of natural gas (for example, containing methane). The reactor (1) for endothermic reactions, in particular high-temperature reactions, in which a commercial gas (P) obtained from the source gas (E) covers the internal space (10) of the reactor, whereas the reactor (1) is configured for passing in the reaction zone (12) the interior (10) of the reactor bed (120) comprising a plurality of solid particles (F), wherein the design of the reactor (1) also allows the feed gas (E) to be supplied to the reaction zone (12), while for heating the feed gas (E) the reactor (1) is configured to heat the solid particles (F) in the reaction zone (12), so that the feed gas (E) in the reaction zone (12) can be heated to the reaction temperature due to heat transfer from the solid particles (F ) to the source gas (E), so that the source product enters into an endothermic reaction to produce sales gas (P), and at the same time, the internal space (10) of the reactor also comprises the first heat accumulation zone (11), in which the heat produced in the reaction zone (12) of commercial gas (P) can be transferred to the solid particles (F) of the reactor bed (120) supplied to the reaction zone (12), and the internal space (10) of the reactor also comprises a second heat accumulation zone (13), in which for preheating of the source gas (E), heat can be transferred from the solid particles (F) of the reactor bed (120) coming from the reaction zone (12) to the source gas (E). The invention also relates to a process in which the reactor (1) according to the invention is used.
EFFECT: creating an improved reactor, which does not use the traditional heating of the endothermic reaction and at the same time provides more efficient operation of the reactor.
