Embodiment 1

[0023] 80% by weight of lauryl nitrate, 15% by weight of succinimide, and 5% by weight of cerium naphthenate. The compounding method is that succinimide and cerium naphthenate are directly added to isooctyl nitrate without heating, and can be uniformly mixed with a little stirring to obtain the additive a.

Embodiment 2

[0025] Amyl nitrate 80% by weight, overbasic synthetic magnesium sulfonate (base value 325mgKOH / g) 10% by weight, benzylamine 10% by weight, the preparation method is the same as in Example 1, and additive b is obtained.

Embodiment 3

[0027] 75% by weight of cetyl nitrate, 7% by weight of overbased calcium petroleum sulfonate (calcium content is 9% by weight), 13% by weight of benzylamine, and 5% by weight of lanthanum naphthenate. The preparation method is the same as in Example 1. Get additive c.

Abstract

The invention discloses a diesel fuel additive and its uses, which comprises 70-80 wt% of nitrates, 0-10 wt% of detersive, 5-15 wt% of dispersing agent, and 0-5 wt% of rare-earth metal naphthenate. The additive can effectively reduce diesel discharge pollution and improve fuel combustion performance.'

Description

technical field [0001] The invention relates to a fuel additive, in particular to a diesel additive for increasing the cetane number of diesel oil and reducing diesel pollution emission and its application. Background technique [0002] With the increasingly stringent environmental protection regulations, the quality index requirements for diesel oil are constantly increasing, especially the cetane number of diesel oil. The cetane number directly affects the pollution emission and fuel economy of diesel oil. However, with the continuous extraction of crude oil, the performance of crude oil deteriorates, and the processing volume of heavy crude oil and sour crude oil continues to increase. Through the existing processing technology, it is difficult for the cetane number of diesel oil to meet the target requirements. Therefore, the development of economical and effective Diesel cetane number additive, very necessary. [0003] The cetane number additive can reduce the temperat...
