Abstract
The invention relates to high-cleaning composite gasoline and a preparation method thereof. The high-cleaning composite gasoline comprises the following components in part by weight: 10 to 25 parts of methanol, 15 to 20 parts of naphtha, 52 to 74 parts of solvent gasoline and 1 to 3 parts of additive, wherein the additive is prepared from 10 weight percent of tridecyl alcohol, 10 weight percent of hexadecyl sodium sulfonate, 20 weight percent of hexadecyl calcium sulfonate, 50 weight percent of naphthenic acid, 2.5 weight percent of tertiary butanol, 2.5 weight percent of isobutanol and 5 weight percent of isopropanol. The preparation method comprises the following steps of: 1) preparing the additive; 2) preparing denatured methanol; and 3) blending the denatured methanol, the naphtha and the solvent gasoline to prepare the high-cleaning composite gasoline. The high-cleaning composite gasoline of the invention has good cold boot, strong anti-corrosion performance, full combustion, powerful motive power and clean discharged tail gas and abundant sources and low cost of raw materials, and can solve the problem that natural fuel is in short supply.
Description
Technical field
The invention provides a kind of gasoline substitute products, be specifically related to a kind of high cleanness composite gasoline and preparation method thereof.
Background technology
Along with Economic development, the insufficient problem of China's oil reserved resources fully manifests.Exploitation cleaning, renewable energy source become the highest problem of concern rate in our economic life.Existing composite lead-free gasoline generally is made up of methyl alcohol, industrial naptha, dimethylbenzene, Virahol, and there is following shortcoming in this kind gasoline: (1) methyl alcohol has certain corrodibility, can produce certain influence to the component of fuel tank, oil circuit and automobile.When (2) temperature was lower than 0 ℃, demixing phenomenon can appear in composite gasoline, influenced the startup of vehicle.When (3) temperature surpassed 40 ℃, methanol activity strengthened, and easily forms vapour stream, thereby air-resistance phenomenon takes place.(4) the industrial naptha colloid is higher, not only can influence the stability of composite gasoline, and can influence the work of engine.
Summary of the invention
The object of the present invention is to provide a kind of high cleanness composite gasoline, its anti-knocking property, good security, resistance to corrosion is strong, reduces exhaust emission.Solved in the background technology existing generally by methyl alcohol, industrial naptha, dimethylbenzene, Virahol form the shortcoming of composite lead-free gasoline.
The present invention is achieved in that described high cleanness composite gasoline is made up of following weight percentages:
10～25 parts of methyl alcohol
15～20 parts of petroleum naphthas
52～74 parts of industrial napthas
1～3 part of additive
Wherein: described additive is by tridecyl alcohol 10%, sodium cetanesulfonate 10%, and hexadecyl calcium sulphonate 20%, naphthenic acid 50%, the trimethyl carbinol 2.5%, isopropylcarbinol 2.5% and Virahol 5% are by weight formulated.
The present invention follows these steps to formulated:
1. with tridecyl alcohol 10%, sodium cetanesulfonate 10%, hexadecyl calcium sulphonate 20%, naphthenic acid 50%, the trimethyl carbinol 2.5%, isopropylcarbinol 2.5% and Virahol 5% are by weight preparation, and thorough mixing obtains additive;
Again with additive with obtain denatured methyl alcohol by the methanol mixed of proportioning weighing;
3. at last denatured methyl alcohol is mixed with industrial naptha and petroleum naphtha by the proportioning weighing, stir, leave standstill tinning after 30 minutes.
The effect of the additive among the present invention is not simply adding up of several raw material simple functions.In the building-up process of high cleanness composite gasoline; additive has not only shortened the chemosynthesis time; changed intermolecular reactive force; the feasible synthetic particulate increased activity that is polymerized; thereby reach the abundant and maximized purpose of chemical energy of atomizing in use; and additive can also be fine suppress the activity of alcohols, greatly reduce the corrodibility of composite gasoline.
Advantage of the present invention:
Cold start-up is good, and resistance to corrosion is strong, sufficient combustion, powerful, exhaust emissions cleaning.The starting material source is abundant, with low cost, can be directly used in all kinds of petrol engines.Can solve the under-supply problem of natural fuel.
Show after testing, every physical and chemical index of high cleanness composite gasoline of the present invention meets the national standard of GB17930-1999 fully, and following data are the detection data at the 93# high cleanness composite gasoline of Research Institute of Petro-Chemical Engineering's analytical test gained (component: 15 parts of methyl alcohol, industrial naptha 69%, 15 parts of petroleum naphthas, additive 1%).

Again methyl alcohol 10KG and additive 1KG mixing are obtained denatured methyl alcohol;
At last petroleum naphtha 10KG, industrial naptha 79KG and denatured methyl alcohol 11KG are mixed, leave standstill after stirring and be packaged into jar in 30 minutes.
Embodiment 2:
With tridecyl alcohol 10%, sodium cetanesulfonate 10%, hexadecyl calcium sulphonate 20%, naphthenic acid 50%, the trimethyl carbinol 2.5%, isopropylcarbinol 2.5% and Virahol 5% are by weight preparation, and thorough mixing obtains additive;
Again methyl alcohol 20KG and additive 2KG mixing are obtained denatured methyl alcohol;
At last petroleum naphtha 20KG, industrial naptha 58KG and denatured methyl alcohol 22KG are mixed, leave standstill after stirring and be packaged into jar in 30 minutes.
In the whole process of production, ventilate and keep away sun, No Open Flames.
Obtain high cleanness composite gasoline by production process, be applicable to industry and civilian.
