Pyrolysis gasoline – py gas – is produced by thermal cracking, as a byproduct of ethylene manufacture. An important feed stock for recovering olefins and aromatics, and a source of benzene by hydrodealkylation (benzene concentrations generally range from 30 to 50%), py gas also contains significant levels (>1%) of dicyclopentadiene (DCPD).
Pyrolysis gasoline is a by-product of ethylene production. Pyrolysis gasoline contains a mixture of hydrocarbon compounds in the C5–C12 boiling range. The primary constituent is benzene, which can range from 25–45% of the stream mass. pyrolysis gasoline is mainly used as a source for recovering benzene and other hydrocarbons. A small amount is sometimes used as refinery feedstock to boost octane in motor fuels.
