The results are interesting for feed tolerant operation and are in-line with other recent studies by our group, where the same behavior was found for a composition variation at 12.5 bar for TiO2 and ZrO2 supported catalysts performed in conventional stainless steel reactors . Hence, our experimental results indicate performance characteristics, which are beneficial for scenarios where tolerance and robustness play important roles. Thus, our study underlines that not just the polymeric reactors, but also the Ru-based catalysts are highly attractive choices for applications beyond earth in general and space mission in particular.
