PROCESS FOR THE SELECTIVE HYDROGENATION OF ACETYLENE TO ETHYLENE

摘要

A process for a liquid phase selective hydrogenation of acetylene to ethylene in a reaction zone in which acetylene is contacted with hydrogen under hydrogenation conditions and a molar ratio of hydrogen to acetylene in the reaction zone is at least (5), preferably at least (9). A molar ratio of hydrogen to carbon monoxide is preferably (10). The acetylene is preferably absorbed in a solvent.
