DEALKYNATION OF OLEFIN AND DIOLEFIN STREAMS

摘要

Lower alkynes are effectively removed from olefin and diolefin streams by contacting the stream containing dissolved hydrogen with a finely divided metal catalyst consisting of copper plus at least one polyvalent activator metal supported on a high surface area gamma alumina containing 0.1 to 1.5 weight percent sodium oxide. The catalyst is easily regenerated by oxidation and hydrogen reduction at moderate temperatures.
