Abstract

See full text

The invention is directed to a process to prepare propylene from a mixture of hydrocarbons by performing the following steps. (a) extracting aromatics from the mixture of hydrocarbons thereby obtaining a mixture of hydrocarbons poor in aromatics, (b) contacting the mixture obtained in step (a) with a heterogeneous cracking catalyst as present in a fixed bed thereby obtaining a cracked effluent, (c) separating propylene from the cracked effluent thereby also obtaining a higher boiling fraction, (d) recycling part of the higher boiling fraction to step (b) and at least 5 wt % of the higher boiling fraction to step (a).
