摘要：Nitroaromatic compounds are hydrogenated in the gas phase to form aromaticamines with hydrogen in the presence of one or more catalysts arranged in stationary orvirtually stationary beds in a reactor. In this process, the catalyst in the reactor is at leastpartly replaced continuously or at periodic intervals. At least 10% of the catalyst isreplaced within each 20 day interval subsequent to start up of the reaction.
