Abstract

The invention provides a preparation method for a highly-clean diesel oil cetane number improver. The improver is obtained by successively uniformly mixing and stirring the following substances in parts by mass: 60-70 parts of glycol dinitrate, 5-15 parts of amyl peroxy-2-ethylhexanoate, 5-15 parts of a cleaning dispersant, 5-10 parts of a cleaning agent, 5-20 parts of a stabilizing agent, and 1-2.5 parts of an antismoke agent. The highly-clean diesel oil cetane number improver is capable of effectively improving the cetane number of clean diesel oil and guaranteeing the cetane number stability of the clean diesel oil for a long time, is extremely high in cost performance, good in safety and simple in manufacturing technology, and is widely applicable to the field of highly-clean diesel oil.

Description

technical field [0001] The invention relates to the field of high-clean diesel additives, in particular to a high-clean diesel cetane number improver. Background technique [0002] Oil is an important support for economic development. At present, with the intensification of exploitation, some high-quality oil resources have been exhausted. The phenomenon of heavy crude oil in various countries in the world is becoming more and more serious. For such problems, countries generally adopt catalytic cracking secondary processing technology to increase the output of light diesel oil, which leads to changes in the quality of petroleum-related products. In the field of diesel oil, the outstanding performance is the decrease of cetane number and the weakening of power performance. [0003] At present, the cetane number of high-clean diesel oil is generally 38-45, which is not less than 45 for ordinary diesel oil stipulated by the national standard, and there is a certain gap. Therefo...
