Fuel oil additive and fuel oil products containing said fuel oil additive

Abstract

The present invention provides a fuel oil additive capable of effectively improving the quality of fuel oils, which comprises an oil-soluble metal salt of organic acid having the general formula MR, where R is an organic acid radical and the corresponding organic acid is a C1-C40 saturated or unsaturated fatty acid, naphthenic acid, aromatic acid or alkylphenol, M is a metal cation and the corresponding metal is an alkali metal, alkali-earth metal, rare-earth metal, transition metal, or the like. The present invention also provides fuel oil products added with the fuel oil additive, including gasoline, diesel oil, kerosene, heavy oil, resid, or the like. The present invention especially provides a gasoline antiknock agent and a gasoline having excellent antiknock property, and this kind of gasoline antiknock agent is characteristic of effectiveness, economy, safety, no environmental pollution, no toxicity to human body, no adverse effect on parts of automobile engine, use convenience, and the like.

Description

RELATED APPLICATIONS [0001] This application is a continuation-in-part of U.S. patent application 10 / 631,965 filed on Aug. 1, 2003, which is a continuation-in-part of international application PCT / CN02 / 00047 filed Feb. 1, 2002, which designated the U.S., and which claims priority from Chinese application 01106124.3 filed on Feb. 1, 2001, all of the foregoing of which are incorporated by reference herein.FIELD OF THE INVENTION [0002] The present invention relates to an improvement of fuel oil performance, and particularly to a fuel oil additive capable of effectively improving the combustion performance of fuel oils in a combustion chamber of automobile and an oil burning boiler and having energy-saving, decontamination and antifriction effects, and the present invention also relates to fuel oil products containing this kind of additive. This invention particularly relates to a gasoline antiknock additive and a gasoline product containing the said antiknock additive. BACKGROUND OF TH...

AI Technical Summary

Benefits of technology

The present invention provides a new fuel oil additive that can improve the quality of oils, reduce carbon deposit and harmful substances in exhaust gas, as well as reducing abrasion and corrosion of engine parts. The additive is an oil-soluble metal salt of organic acid that has good cleaning, energy-saving, antifriction, and antiknock properties. The additive can be used in small amounts and is effective in reducing oil consumption and discharge of pollutants. The metal salt can be commercially purchased or synthesized by well-known methods. The fuel oils containing the additive have better combustion performance and are favorable to maintaining normal working conditions of an engine combustion system.

Problems solved by technology

In order to produce a high-octane number gasoline, one method to do so is the improvement of petroleum refining technology by means of catalytic cracking, alkylation, platinum reforming, or the like, but the technological improvement is limited by a variety of factors, including reform and renovation of equipment, funds, a complete set of techniques, and so on; and another method which effectively and simply adds a suitable antiknock agent into gasoline.

It has been found in use that the former is unfavorable to the storage of oils, and the latter results in abrasion of the engine and causes new environmental pollution.

Problems common to these antiknock agents are low effectiveness, large amount, and diseconomy and inconvenience.

Tetraethyl lead used for many years has been prohibited because of the toxicity of lead.

Among these compounds, ferrocene has been prohibited because of a harmful effect on engines, the manganese-base antiknock agents have been limited and prohibited because of their poisonous effect on human nerves and environment, and complexes of cerium and α, β-diketones have too high a cost to popularize.
