Apparatus and method for studying endothermic reactions

摘要

The invention relates to an apparatus and a method for carrying out heterogeneously catalyzed reactions or gas phase reactions which have a strong endotherm. The device comprises a flow-through reaction chamber with at least one thermal sleeve (2), a pressure-bearing shell (1) and an insulating sleeve (3), wherein the thermal sleeve (2) is arranged in the direction of the longitudinal axis of the reaction chamber. In a preferred embodiment, the reaction chamber comprises a lining tube (8). The end of the thermal sleeve (2) is arranged above the catalyst receiver (5) so that the temperature profile can be recorded within the reactor and the catalyst bed. The one or more Mantelheizleiter (4) are in direct contact with the pressure-bearing sheath (1). Preferably, the device has a plurality of Mantelheizleitern (4), which can be independently controlled or independently controlled. Preferably, the device is operated at a temperature in the range of 750 to 1150 ° C and a pressure of up to 50 bar. In particular, the device according to the invention is used to investigate the pyrolysis of methane, the steam and the dry reforming of natural gas and the reverse water gas shift reaction.
