Title:
【発明の名称】ガス相において触媒作用により有機化合物を水素化する方法
Document Type and Number:
Japanese Patent JPH0819006
Kind Code:
B2
Abstract:
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.
