Dihydro Addition - Cycloalkene Hydrogenation

1 Drivers Ibr Performing Cycloalkene Hydrogenation in Micro Reactors 

The cyclohexene hydrogenation is a well-studied process especially in conventional trickle-bed reactors (see original citations in [11,12]) and thus serves well as a model reaction. In particular, flow-pattern maps were derived and kinetics were determined. In addition, mass transfer can be analysed quantitatively for new reactor concepts and processing conditions, as overall mass transfer coefficients were determined and energy dissipations are known. In lieu of benchmarking micro-reactor performance to that of conventional equipment such as trickle-bed reactors, such a knowledge base facilitates proper, reliable and detailed comparison. 

Cyclohexene hydrogenation is a fast process so mass transfer limitations are likely [12]. Processing at room temperature and atmospheric pressure reduces the technical expenditure for experiments. 

Owing to the exothermic nature of hydrogenations, the avoidance of hot spots causing reductions in selectivity and catalytic activity is a second driver [11].
