Method of catalytically hydrogenating organic compounds in gasphase and heat exchanger used in the process

摘要

The invention relates to a method for the catalytic hydrogenation of organic compounds in the gas phase. The circulated gas leaving the hydrogenation reactor and containing the reaction product is compressed in a compressor without prior cooling and then heats the feedstocks to reaction temperature in a superheater. The circulated gas stream is further cooled in a hot gas heat exchanger by reactants conducted in counter-current; as a result the reaction product substantially condenses out. After addition of fresh gas and feedstock, the circulated gas is again passed to the hydrogenation reactor via a purification column.
