Abstract
The invention belongs to the technical field of vehicle fuel oil, and concretely relates to a sec-butyl alcohol gasoline. The sec-butyl alcohol gasoline is composed of gasoline and sec-butyl alcohol, and the mass percentage concentration of the sec-butyl alcohol is 10-30%. The highest content of the sec-butyl alcohol in the sec-butyl alcohol gasoline can reach 30% without using an additive or installing an engine, so the pollution problem of automobile tail gas is effectively reduced, and the fuel cost is reduced. The sec-butyl alcohol gasoline formed by mixing 10-30mass% of the sec-butyl alcohol with 93# gasoline can completely substitute 93# gasoline. The sec-butyl alcohol has a branched chain structure, has a high octane number, can be easily biodegraded, has a good environmental protection performance and can improve the anti-knock property of the gasoline. The sec-butyl alcohol is generated by reacting butylene in a low-price refinery cracking gas with water, the production power of the sec-butyl alcohol in China is excess, the price of the sec-butyl alcohol is low, and the highest content of the sec-butyl alcohol in the sec-butyl alcohol gasoline can reach 30%, so the cost of the sec-butyl alcohol gasoline is low.
Description
Technical field
The present invention relates to the fuel oil for vehicles technical field, be specially a kind of sec-butyl alcohol gasoline.
Background technology
Along with the shortage of petroleum resources, constantly the raising up of oil price, resource, the energy, environmental revolution are carried out in society and expanding economy requirement.The blended gasoline replacing gasoline becomes one of focus of research now as vehicle traction fuel.Existing blended gasoline has methanol gasoline, ethanol petrol, methyl tertiary butyl ether gasoline, butanol vapour wet goods usually.Butanols gasoline usually is in harmonious proportion and forms with biological butanol and gasoline, wherein biological butanol is n-butyl alcohol, 2-butanols and butanols isomer mixture, the butanol vapour oil phase is than methanol gasoline and ethanol petrol, have following advantage: the compatibleness of butanols and gasoline is better, can reach higher ratio of mixture with gasoline; Butanols has higher energy density, has fuel economy preferably; A little less than the butanols wetting ability, can be miscible with gasoline.But, in the preparation process of biological butanol, need to use larger evaporation, heating, the facility such as cooling, so investment cost is high, production cost is high, and easily environment is produced to secondary pollution.Butanols gasoline also be faced with thereupon cost high, easily environment is produced to the challenge such as secondary pollution.
Summary of the invention
The object of the invention is to for overcoming the defect of prior art, and provide a kind of cost low, in the situation that do not need to transform engine and do not need to use additive, the mass percent of sec-butyl alcohol can be up to 30% sec-butyl alcohol gasoline.
For achieving the above object, the present invention by the following technical solutions: a kind of sec-butyl alcohol gasoline, described sec-butyl alcohol gasoline is comprised of gasoline and sec-butyl alcohol, the mass percent concentration of described sec-butyl alcohol is 10-30%.
Described gasoline is No. 93 gasoline.
Described sec-butyl alcohol is 1-butylene in refinery's splitting gas and 2-butylene generate with water generation hydration reaction respectively under the effect of an acidic catalyst sec-butyl alcohol.
The mass percent concentration of described sec-butyl alcohol is 20-30%.
The mass percent concentration of described sec-butyl alcohol is 25-30%.
The mass percent concentration of described sec-butyl alcohol is 30%.
The preparation technology of sec-butyl alcohol gasoline: under normal temperature and pressure, gasoline and sec-butyl alcohol are mixed in proportion, filter and get final product.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is in harmonious proportion and forms sec-butyl alcohol gasoline with sec-butyl alcohol and gasoline, in the situation that do not use additive and do not need refiting engine, the content of sec-butyl alcohol can, up to 30%, can effectively reduce the pollution problem of cost and the reduction vehicle exhaust of fuel.By the sec-butyl alcohol gasoline of sec-butyl alcohol and No. 93 gasoline mediation formation, the mass percent of sec-butyl alcohol is 10-30%, can substitute No. 93 gasoline fully.Because the structure of sec-butyl alcohol is branched chain type, octane value is high, readily biodegradable more, and good environmental protection, and can improve the anti-knocking property of gasoline.The butylene of sec-butyl alcohol in cheap refinery's splitting gas reacts generation with water, and the sec-butyl alcohol production capacity surplus of China, the Costco Wholesale of sec-butyl alcohol is low, and in sec-butyl alcohol gasoline, the content of sec-butyl alcohol is higher than the content of alcohol in other alcohol base gasoline simultaneously, so the cost of sec-butyl alcohol gasoline has more advantage.
