SELECTIVE HYDROGENATION OF BUTADIENE

摘要

A process for the selective hydrogenation of dienes in mixed streams of olefin containing hydrocarbons, such as butadiene in a mixed C₄ stream with minimum loss of monoolefins is disclosed wherein the reactor is operated at conditions which induce pulse flow. The pulse flow is induced in a downflow boiling point reactor by vaporization of a portion of the liquid feed at proper conditions.
