Abstract

The invention relates to a diesel oil cetane number improving agent composition, which contains organic peroxide and organic amine. The invention also provides diesel oil, and the cetane number improving agent adopted by the diesel oil is the diesel oil cetane number improving agent composition provided by the invention. The diesel oil cetane number improving agent composition overcomes the defect that the cetane number of the diesel oil using the organic peroxide cetane number improving agent composition goes down along the time, and effectively improves the cetane number of the diesel oil and keeps the stability thereof. The diesel oil cetane number improving agent composition can be applied to light diesel oil, heavy diesel oil, Fischer-Tropsch diesel oil and boiler fuel oil. The diesel oil added with the diesel oil cetane number improving agent composition has the improved diesel oil cetane number which has stability, thus the combustion performance is improved, the power performance and the economical performance of an engine are improved, and the tail gas emission pollution of the engine is improved.

Description

technical field [0001] The invention relates to a diesel cetane number improver composition and diesel oil containing the diesel cetane number improver composition. Background technique [0002] With the increase of diesel consumption, the quality of diesel is also higher and higher, especially the cetane index of diesel is higher and higher. The cetane number is an important indicator of diesel combustion performance, which has an impact on engine cold start, exhaust emissions and combustion noise. my country's national standard for diesel oil requires that the cetane number of light diesel oil is not less than 45, and the cetane number of light diesel oil produced from intermediate crude oil or mixed with catalytic components is allowed to be not less than 40. The average cetane number of diesel oil in the world is around 50, which is roughly the same as that in my country. The main factor affecting the cetane number of diesel oil is the composition of diesel blending co...
