Abstract
An additive for increasing octane number of fuel oil is prepared from mixed solent of benzene, n-butanol and methyl acetone, allyl tert-butyl ether as anti-exploding agent, mixture of sulfonated sodium dioctoate succinate and alkali-earth metal sulfonate as cleaning disperser and bialkylphosphoric acid as anticorrosion agent through proportionally mixing and stirring for 30 min. Its advantages are high effect, reduced exhaustion of tial gas and saving fuel oil.
Description
The present invention relates to a kind of fuel oil additive and method for making thereof, particularly a kind of energy dopes for gasoline and method for making thereof.
Octane value is an index of weighing the gasoline anti-knocking property, and the more little expression anti-knocking property of its value are poor more.Be boosting of octane rating, strengthen the gasoline anti-knocking property, two kinds of methods are arranged at present; First kind is that low-octane straight-run spirit is done deep processing, and its pertinent literature is in " Chinese Appropriate technology database ", and name is called " E type gasoline " (CSTAD:44520); Second kind is to add the octane value elevator in gasoline.
First method is closely-related with petroleum refining process, its complex process, and required expense is higher.
Second method is both economical, and is simple, is ordinary method.So far, people have developed some organometallicss as octane promoter, elevator as boosting of octane rating, wherein widely used is tetraethyllead, but the problem that exists is that tetraethyllead has severe toxicity, very big to human body harm, but and the ejecta contaminate environment after its effect, for this reason, State Bureau of Environmental Protection is stipulated " motor spirit that the whole nation produces after 2000 must be unleaded, and import prohibition, producing and selling are used as the tetraethyllead of gasoline dope ".
1970's, grown up a kind of additive of unleaded type boosting of octane rating was methyl tertiary butyl ether, its pertinent literature is in " Chinese Appropriate technology database ", and name is called " production of methyl tertiary butyl ether reaches the feasibility study of producing 20000 tons of MTBE devices in auxiliary reagent factory's construction per year " (CSTAD:58753); But it adds in the oil product modulation process, forms and function singleness, and over-all properties is very not good.
The purpose of this invention is to provide not phosphorous in a kind of prescription, chlorine, lead and other elements, effect is lasting, stable, and have peace and quiet, anticorrosive, as to reduce multiple functions such as discharging and oil consumption combined additive concurrently, and can strengthen its anti-knocking property, improve a kind of additive and method for making thereof that improves octane number of fuel oil of gasoline over-all properties.
The objective of the invention is to be achieved through the following technical solutions:
A kind of additive that improves octane number of fuel oil, comprise mixed solvent, octane promoter, detergent-dispersant additive, corrosion inhibitor etc., mixed solvent comprises benzene, propyl carbinol, methylacetone, octane promoter is the allyl group tertbutyl ether, detergent-dispersant additive is the mixture after sulfosuccinate two caprylic acid sodium salt and alkaline earth metal sulfonate are compound, corrosion inhibitor is two alkylphosphonic acid carboxylic acids, benzene during its mixed solvent mixes, and the volume ratio of propyl carbinol, methylacetone is 30-40%: 10-20%: 30-40%; The mass percent of each component is 70%～80%: 10%～15% when allyl group tertbutyl ether, sulfosuccinate two caprylic acid sodium salt and the mixture of alkaline earth metal sulfonate, the mixing of two alkylphosphonic acid carboxylic acid: 10%～15%; Volume ratio when mixed solvent mixes with the mixture of octane promoter, detergent-dispersant additive, corrosion inhibitor is 1: 1.
A kind of manufacture method that improves the octane number of fuel oil additive, it with each component benzene, propyl carbinol, methylacetone in the mixed solvent is earlier by volume: 30-40%: 10-20%: 30-40% mixes, and it is standby to obtain mixed solvent A; Again with sulfosuccinate two caprylic acid sodium salt and alkaline earth metal sulfonate by mass ratio be 1: 1 compound, obtain compounding mixture B, be 70%～80%: 10%～15% by mass percentage with allyl group tertbutyl ether, compounding mixture B, two alkylphosphonic acid carboxylic acid then: 10%～15% mixed obtains mixture C thus; At last, mixed solvent A and mixture C are mixed by 1: 1 volume ratio, mechanical stirring is about 30 minutes, and stirring stops, quantitatively canned getting final product.
The mass ratio of described sulfosuccinate two caprylic acid sodium salt and alkaline earth metal sulfonate compound tense is 1: 1.
During described mixed solvent mixed, the optimum volume ratio of benzene, propyl carbinol, methylacetone was 40%: 20%: 40%.
Octane value elevator according to the technique scheme preparation, by peace and quiet, disperse settling, colloid in the gasoline, guarantee normal air-fuel ratio, thereby further strengthen the anti-knocking property of gasoline, and have satisfactory stability, compatibleness and erosion resistance can significantly improve the octane value of gasoline, reduce exhaust emissions and save fuel oil, belong to and have multi-functional oil dope.This product self is not leaded in addition, chlorine, elements such as phosphorus, can not produce problem of environmental pollution after the use, for meeting the green product of national environmental protection and energy-conservation requirement, therefore, social benefit is very huge, mensuration through automobile carrier energy utilization monitoring center of the Ministry of Communications and national petroleum products quality supervision and test center, octane value elevator prepared in accordance with the present invention, addition only is 5 ‰ o'clock, octane value can improve 4 units, rate of economizing gasoline reaches 2.3%, and this action effect is suitable with the vehicle energy saving fuel oil additive of the logical some popularization of country, meets the regulation of the industry standard JT/T306-1997 of the Ministry of Communications " vehicle energy saving product use technology condition ".
The invention will be further described below in conjunction with embodiment:
