Heterogeneous hydrogenation is the most widely applied catalytic reaction in the fine chemicals industry. The methodological versatility, the outstanding atom and energy efficiency and the ever increasing pressure from regulatory agencies for ecological and energetical sound processes makes heterogeneous catalytic hydrogenation still to one of the most important and most widely used transformation on industrial scale. To establish economic useful, robust and safe processes on industrial scale a development considering all important factors is crucial.

An economic hydrogenation process requires a high catalyst productivity and selectivity in combination with low metal losses, good catalyst reusability as well as the useful inclusion into the overall process (telescoping of reaction mixture). Even though heterogeneous catalyt ... ...
