The invention relates to a clean synthetic gasoline massively used in automobiles and a preparation technology thereof. The gasoline is prepared by the following raw materials according to parts by weight: methanol, naphtha, MTBE, gasoline and toluene. The invention not only obviously improves the burning emission of automobiles and protects the atmospheric environment, but also maintains the combustion system of the automobile to be clean, and leads oil lines to be smooth, the atomizing of fuel injection of spray nozzles to be fine and the gasoline to fully burn; the automobile dynamic performance is improved, the fuel consumption is reduced, the service life of engines are prolonged, and the maintenance cost is reduced, namely, the use of the clean gasoline is beneficial to both the nation and vehicle owners.
Description
Technical field
The present invention relates to a kind of gasoline, relate in particular to a kind of quilt and be used for clean synthetic gasoline and preparation technology thereof on the automobile in a large number.
Background technology
Gasoline is related to national economy, relates to one of important substance of all trades and professions; Especially be used in automotive field in a large number.Show according to State Statistics Bureau statistics: China's auto output every year is with about 12% speed increment, to the recoverable amount of automobile in 2003 to reach more than 2,000 ten thousand, nearly 6,000 ten thousand tons of motor spirit consumption, petroleum demand amount in 2003 reaches about 2.4 hundred million tons, breach is above 7,000 ten thousand tons, processed oil accounts for about 2,800 ten thousand tons, the relevant expert estimates, China's refined oil demand surge in 10 years from now on, reach 1.1 hundred million tons to gasoline consumption in 2010, therefore the relevant expert points out that petroleum resources are limited after all, the utilization new technology, novel process, novel method, novel material is sought the meter that the substitute products of oil-----new forms of energy are only human sciences's long term growth.
In recent years, China is in the research of alternative fuel for cars, great amount of manpower and financial resources have been dropped into, yet the industrialization process of substitute products fuel and speed, reach desired wish far away and produce effects, its reason is said with the words of the former minister of Ministry of Science and Technology Xu Guanhua: " research in past probably forever can not industrialization, because cost is too high, people can't accept "; Just China city is to use or to be about to promote the use of ethanol petrol at present, and natural gas used for automobile is not equally broken away from the too high puzzlement of cost yet.The grant programme so country has to study is so that make the ethanol vapor oil and gas fair with the conventional gasoline with the trade mark.At present China authoritative sources of Beijing Public Transport main office of taking the lead in equipping natural gas engine admits: current gasfueled vehicles also are the operation needs that can only satisfy street, Chang'an one line, equally also do not break away from the too high destiny of cost.
Cause the air-polluting source according to understanding,, currently how to make huge automobile reach environmental requirement to become the problem that government department has a headache very much mainly from motor vehicle exhaust.
Simultaneously, petroleum resources are again non-renewable energies, are limited on the earth; The about 1369GT of prospective oil that the existing known whole world is confirmed presses the about 31GT of output now, calculates with year volume increase 1%, can exploit more than 30 year.Therefore, because the limitation of oil reserve and exploitation also causes present gas price to improve constantly, therefore how making good use of valuable petroleum products, improve application efficiency, save petroleum resources to greatest extent, reduce cost, is the task of top priority.
Summary of the invention
The present invention is directed to the problem of above-mentioned existence, through for many years effort and experiment and develop a kind of clean synthetic gasoline and preparation technology thereof.The present invention mainly is byproduct and the alcohol mixture based on each refinery, ethylene plant etc., is auxilliary with the C5-C15 hydrocarbon mixture, is prepared into clean synthetic gasoline, has solved the problem that atmospheric pollution is serious, production cost is high of present gasoline.
Another object of the present invention is to provide a kind of preparation technology who prepares clean synthetic gasoline.
Clean synthetic gasoline of the present invention is counted ratio by following raw materials in parts by weight and is prepared from methyl alcohol: petroleum naphtha: methyl tertiary butyl ether MTBE: gasoline: toluene=200-650:85-300:50-200:150-650:30-180.
Clean synthetic gasoline of the present invention is prepared from methyl alcohol by the preferred weight portion rate of following each raw material: petroleum naphtha: methyl tertiary butyl ether MTBE: gasoline: toluene=300-400:150-230:85-120:230-400:65-100.
Described gasoline is any among 90#, 93#, 95#, the 97#.
The preparation technology of clean synthetic gasoline of the present invention comprises the steps:
(1). mix: with methyl alcohol, petroleum naphtha, methyl tertiary butyl ether MTBE, gasoline, toluene mixes by above-mentioned weight ratio;
(2). reaction: mixed each raw material is dropped into reactor, react at normal temperatures, the time is 10-50 minutes;
(3). filter: the first finished product of gasoline that reactor is generated filters through filter.
Advantageous effect of the present invention is as follows:
Environmental protection, efficient, cost is low is three big advantages of clean synthetic gasoline of the present invention.
1. clean synthetic gasoline of the present invention has the higher spatter property and the value of environmental protection, be embodied in and reduce a large amount of motor vehicle exhausts, significantly reducing of hydrocarbon polymer in the exhaust emissions (HC), carbon monoxide (CO), oxynitride (NOx) is beneficial to everyone.
2. the present invention makes vehicle fuel system cleaning, and the fogging degree of oil product improves, gas mixture perfect combustion, and power reaches maximization, thereby has reduced cost greatly, has more powerful absolute predominance and competitive power on price.
3. technology of the present invention is easy, is easy to grasp, and starting material can make in coal, Sweet natural gas and biological substance waste material, and the process of prepared in reaction is all finished under cold condition.
4. the present invention need not change the structure of existing motor car engine and transform, and just can reach the effect of fuel-saving environmental protection, possesses the condition that industry is applied.
In sum, the present invention not only makes automobile burning discharging obtain significantly to improve, and is beneficial to the protection atmospheric environment, and it can make the firing system of automobile, and particularly oil circuit, oil nozzle, intake valve keep clean.As oil circuit, oil nozzle, intake valve in prime the fuel system settling is arranged, the motor spirit that also can be cleaned dissolving washes.So, make oil circuit smooth and easy, the oil nozzle oil atomizing is good, and gasoline fully burns, and automobile dynamic quality obtains to improve, and fuel oil consumption reduces, and engine life prolongs, and maintenance cost reduces.Thus, the use of clean gasoline of the present invention is all favourable to country, car owner.Not only have the certain social benefit, and also have tangible economic benefit.
