Improvement of the Cetane Number of Diesel Engine Fuels.

摘要

Disclosed is a novel cetane number improver additive for diesel engine fuels comprising tetralin hydroperoxide as the active ingredient. A diesel engine fuel composition having a high cetane number may be obtained by adding this additive to a diesel engine fuel in such an amount as to adjust its peroxide number to a value of 100 to 1,000. Also disclosed is a process for the production of a diesel engine fuel which comprises the steps of hdyrogenating a naphthalene- or alkylnaphthalenes-containing hydrocarbon oil and partially oxidizing the hydrogenated oil to yield a hydrocarbon oil containing tetralin hydroperoxide.
