ABSTRACT:
A process for the catalytic hydrogenation of organic compounds in the gas phase. The reaction product-containing circulating gas leaving the hydrogenation reactor is compressed without prior cooling, and is then used to heat the starting materials in a superheater to the reaction temperature. The circulating gas stream is further cooled in a hot-gas heat exchanger by cold reactants in a counter-current manner; as a result, substantially all the reaction product condenses out leaving recycle gas. After addition of fresh gas and starting material, the recycle gas is returned via a purification column to the hydrogenation reactor.
