Abstract

Ethylene production by pyrolysis of hydrocarbon gases (ethane, propane, butane) and liquid fractions provides better selectivity to ethylene at higher temperatures, as has been well documented in studies. Temperature increase accelerates chainradical reactions of ethylene formation. Acceleration of chain-radical process can be achieved at a given temperature by the presence of an initiating agent of radical formation in the feedstock. Bimolecular reaction of allene (propadiene) with either alkane or alkene hydrocarbons and is an extremely rapid reaction of radicals formation because the endothermicity of this reaction is small and steric ratio is high. This paper considers the use of allene as the initiator of chainradical reactions of pyrolysis. Keywords: pyrolysis, propadiene (allene), radical chain reactions.
