Pygas or pyrolysis gasoline is a naphtha-range mixture which contains aromatics, olefins and paraffins ranging from C5s to C12s.
It has a high octane number. It is a by-product of high temperature naphtha/propane/gasoil cracking during ethylene and propylene production.
Pygas is generally used as a gasoline blending mixture due to its high octane number.
Benzene rich pygas streams are used as feedstock for the aromatic (benzene) extraction process.
