摘要
A low temperature on-purpose propylene production method is described. The method includes autometathesis of butene streams without an initial ethylene feedstock stream using supported autometathesis catalysts that are active at low temperatures. The low temperature allows for liquid phase reactions, which increases the selective production of propylene. The lack of an initial ethylene feedstock stream and low reaction temperature also reduces coking on the autometathesis catalysts, thus extending its lifetime.
