Catalytic reforming processes produce olefin contaminants in aromatics streams via paraffin dehydrogenation side reactions. Operating catalytic reformers at higher severity results in higher yields of valuable aromatics, but it also results in higher olefins content in the reformate.
Olefins must be removed from:
Historically, olefins have been removed from aromatics streams in treaters using activated clay to promote the acid alkylation of olefins with aromatic molecules, thereby producing heavier compounds further separated by fractionation.
