Abstract
A first stream containing 1,3-butadiene, Cacetylenes, and optionally Chydrocarbons, is mixed with a portion of the liquid recycle stream from a Cacetylene hydrogenation reactor containing hydrogenated Cacetylenes and a molecular hydrogen-containing stream, the resulting mixed stream is then fed to a Cacetylene hydrogenation reactor to selectively hydrogenate the Cacetylenes in the crude butadiene stream without appreciable 1,3-butadiene conversion.
