Steam cracking product yields versus feedstock

	Product Yields
Feedstock source	Ethylene weight %	Propylene weight %	Butadiene weight %	Aromatics (a) weight%	Other (b) weight %
Ethane	84.0	1.4	1.4	0.4	12.8
Propane	45.0	14.0	2.0	3.5	35.5
Butane	44.0	17.3	3.0	3.4	32.3
Naphtha (c)	34.4	14.4	4.9	14.0	32.3
Gas oil (d)	25.5	13.5	4.9	12.8	43.3
(a) Includes benzene, toluene, xylenes and any other aromatics. (b) Includes hydrogen, methane, butenes, non-aromatic portion of pyrolysis gasoline and fuel oil. (c) Full-range naphtha (as differentiated from light or heavy naphtha). (d) The portion of petroleum crude oil that has a boiling range of about 250 to 550 °C (480 to 1020 °F). That encompasses the boiling range of atmospheric gas oil (AGO) produced by the atmospheric distillation of petroleum crude oil and the boiling range of vacuum gas oil (VGO) produced by the vacuum distillation of petroleum crude oil. }
