Abstract
The present disclosure relates to processes for improved yields of propylene via metathesis, primarily from the conversion of C4 and C5+ olefins obtained from steam or fluid catalytic cracking of hydrocarbons. In particular, the present disclosure relates to processes for preparing propylene by improved isomerization of 1-butene to 2-butene relative to the metathesis reaction.
