The optimal operating area (Pareto front) was identified using an in-silico multi-objective optimization for residence time and conversion (Figure ). It can be observed that residence times of 4.25 min can still provide conversion >99% with a space-time yield of 1.8 kg L -1 h -1 . Increasing the space-time yield to 2.8 kg L -1 h -1 results in a decrease of residence time to 2.6 min at 95% conversion.
