Abstract
Process for hydrogenating aromatic compounds over a solid catalyst in the presence of a hydrogen-containing gas comprising a first reactor operated in loop mode, a second reactor operated in straight pass, at least part of the output of the first reactor is supplied to the second reactor, characterized in that the first reactor is configured as a trickle bed reactor and is operated in trickle bed mode and the second reactor is operated such that the catalyst present therein is partially flooded.
