ABSTRACT:
The present invention relates to a process for selectively producing C3olefins from a catalytically cracked or thermally cracked naphtha stream by fractionating the naphtha feed to obtain at least a C6rich fraction and feeding the C6rich fraction into a reaction stage at a point wherein the residence time of the C6rich fraction is minimized.
