Abstract
The invention discloses an additive for oxidation stability of diesel oil, consisting of the following components in parts by weight: 1.5-7.5 parts of antioxidant, 8-12 parts of dispersant, 2-5 parts of metal deactivator and 50-75 parts of basic diesel oil. The additive for oxidation stability of diesel oil can be added in the diesel oil so as to obviously improve the stability of the diesel oil, greatly improve the quality of the diesel oil and prolong the storage period, the conveyance period and the service life of petroleum products.
Description
Technical field
The present invention relates to a kind of diesel-dope, relate in particular to a kind of additive for oxidation stability of diesel oil of forming with inhibitor, dispersion agent and metal passivator.
Background technology
In recent years; Along with diesel engine performance improve greatly and world wide in the energy dilemma that constantly occurs and automobile emission regulation more and more tighter; The technological merit of diesel vehicle is more and more obvious, and its owning amount increases just year by year, thereby to the also average annual growth of demand of diesel oil.Be to adopt the working method of this deep processing of catalytic cracking to obtain with the major part in the diesel oil at present.Yet the stability in storage of this diesel oil is relatively poor, stores the back and is prone to form insolubles, has had a strong impact on the works better and the complete machine performance of engine fuel supply system.So stability in storage how to improve diesel oil is the important topic that people are concerned about all the time.
Summary of the invention
The invention provides a kind of generation that can effectively suppress total insoluble substance in the diesel oil, can significantly improve the stability of diesel oil, improve the quality and the quality of diesel oil greatly, prolong the accumulating of processed oil and the additive for oxidation stability of diesel oil in work-ing life.
Additive for oxidation stability of diesel oil of the present invention is the inhibitor by 1.5-7.5 part (weight); The metal passivator of the dispersion agent of 8-12 part (weight), 2-5 part (weight) and 50-75 part basis diesel oil are formed; Preferably, the amount of inhibitor is 4 parts (weight), dispersion agent 10 parts of (weight), metal passivator 3 parts of (weight), 60 parts of basic diesel oil (weight) in the additive for oxidation stability of diesel oil of the present invention.
Inhibitor used in the present invention is for having the diphenylamine derivatives of following structural formula (I):
Used dispersion agent is the multipolymer of lauryl methacrylate and DIETHANOL AMINE ylmethyl vinylformic acid ethyl ester among the present invention; Its number-average molecular weight is 2000-5000, and used metal passivator is N, N '-two inferior bigcatkin willow-1; The 2-tn, said basic diesel oil can be catalytic cracking diesel oil.
Additive for oxidation stability of diesel oil of the present invention is by inhibitor, and dispersion agent and metal passivator and solvent toluene are formed, and wherein inhibitor can effectively suppress diesel oil oxidation acidic substance and gelationus generation in storing and using; Dispersion agent can disperse the sediment that produces in the diesel oil, and the sediment particle is diminished, and prevents blocking filter, and inhibitor and dispersion agent synergy can more effectively suppress the generation of total insoluble substance in the diesel oil, thereby significantly improve the stability of diesel oil.
Addition by 0.5-1.5% directly joins additive of the present invention in the diesel oil, is heated to 30-50 ℃ and stirs and get final product.
The invention has the beneficial effects as follows: additive adds the stability that can significantly improve diesel oil in the diesel oil, improves the quality and the quality of diesel oil greatly, has prolonged the accumulating and the work-ing life of processed oil.
