-20# Automotive Diesel Oil(VI)

Diesel oil, a fuel used in diesel engine, is a complicated mixture of hydrocarbons (carbon atom number being 10~22) and belongs to light petroleum product, which is made by mixing diesel distillates produced in the crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking processes and can also be prepared via shale oil processing and coal liquefaction.
