Highly Characterized Reference Standard: Pyrolysis Gasoline
11 November 2015

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). This application note demonstrates the characterization of a reference standard of py gas.
