Diesel Fuel - an overview ScienceDirect Topics

Diesel oil is a complex mixture produced by the distillation of crude oil. It consists of hydrocarbons having carbon numbers predominantly in the range of C9–C20 and boiling points in the range of ∼163–357C (325–675F). Diesel fuel no. 1 is a straight-run middle distillate with a boiling range consistent with that of kerosene.
