Abstract
The C to C cut from a cracking process containing propylene, butane, 1-butene, 2-butene and acetylenic and diene components including butadiene are preferentially converted to propylene. The cut is simultaneously fractionated and catalytically hydrogenated to hydrogenate the acetylenic and diene components. The fractionation and subsequent separation recovers a C component comprising a mixture of isobutene, 1-butene and 2-butene. This C component is then further simultaneously fractionated and catalytically hydrogenated and hydroisomerized to hydrogenate remaining butadiene, remove isobutene overhead and convert 1-butene to 2-butene leaving a bottoms of 2-butene. The 2-butene is then injected with ethylene and catalytically metathesized to form propylene.
