Fuel oil additive and fuel oil products containing the 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 to 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

[0001] 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 added to this kind of additive. This invention particularly relates to a gasoline antiknock additive and a gasoline product containing the antiknock additive.[0002] The combustion performance in a combustion chamber of automobile and an oil burning boiler is one of important performance indexes, and it determines whether a fuel oil has properties of energy-saving, environment protection, and the like. For a gasoline product, an important performance index is the antiknock property, and its antiknock index is generally expressed as the average value of an octane number determined by research method (RON) a...

AI Technical Summary

Benefits of technology

0039] By a large quantity of applications and checks of authorized departments, it has been similarly proved that the fuel oil additive of the present invention can also be used in diesel and kerosene automobiles and achieve very remarkable functions and effects on cleaning, energy saving, antifriction of related parts of engine and anticorrosion of related parts of engine. Namely, the present invention also provides the additive for the purposes of cleaning, energy saving, anticorro-sion, antifriction additive of automobile fuel oils, such as diesel oil, kerosene, and the like.

0040] By a large quantity of applications and checks of authorized departments, it has also been proved that the fuel oil additive of the present invention can be used in heavy oil, resid and diesel oil and kerosene combustion furnaces and achieve very remarkable functions and effects on cleaning, energy saving, anticorrosion, therefore, the present invention also provides the additive for the purposes of cleaning, energy saving, of fuel oils, such as heavy oil, and the like.

0041] In short, the oil-soluble metal salts of organic acids used by the present invention have no harmful substances, no peculiar smell and no toxicity, do not pollute the environment and harm the health, do not exert adverse effects on parts of engine, greatly enhance the combustion performance of fuel oils with only a very small amount, especially increase the octane number gasoline and impart good antiknock property to gasoline, thus they have advantages of use convenience, high efficiency, low cost and simple production technique; the gasoline added to the antiknock agent reaches or exceeds the national and international standards in all technical, economic and environmental indexes and do not affect the tail-gas purifier of automobiles, thus they can completely become a new-generation product for replacing tetraethyl lead.

Problems solved by technology

In order to produce a high-octane number gasoline, one method 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 equipments, funds, a complete set of techniques, and so on; and another method is the addition of a suitable antiknock agent into gasoline.

It has been found in uses that the former is unfavorable to the storage of oils, and the latter results in abrasion of 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 engine, the manganese-base antiknock agents have been limited and prohibited because of its poisonous effect on human nerves and environment, and complexes of cerium and .A-inverted., -diones have a too high cost to popularize.
