Furthermore, extensive investigations are performed to reveal information on mechanical strength and heat removal performance of the polymeric reactor material. We found a certain temperature increase during reaction, which agrees with calculations. Moreover, the polymeric material was deformed by the catalyst particles and inert glass beads resulting in embossments of the particles in the polymeric reactor wall. However, both mechanical strength and heat removal performance is sufficient, while Raman microscopy confirm the absence of significant chemical degradation of the polymer. Hence, this study establishes the feasibility of using polymeric reactors for thermocatalytic processes, which opens the door to novel applications both on Earth and in space.
