Abstract
A process for the conversion of linear pentenes to propylene is disclosed. The process may include feeding hydrogen and a C5-olefin containing stream comprising linear pentenes, dienes, acetylenes, and cyclopentene to a catalytic distillation reactor system. Concurrently in the catalytic distillation reactor system, the acetylenes and dienes may be hydrogenated and the C5-olefin containing stream may be fractionated, thereby recovering an overheads fraction comprising the linear pentenes, a side draw fraction comprising the cyclopentene, and a bottoms fraction. In some embodiments, at least a portion of the overheads fraction may then be fed to a metathesis reactor for converting the linear pentenes to propylene.
