Problems solved by technology

As a result, the octane number of ethanol gasoline used in vehicles has decreased and cannot meet the specification requirements. At the same time, wastewater containing gasoline and ethanol needs special treatment before it can be discharged.
[0004] In view of the fact that ethanol gasoline may have oil-water separation and low temperature resistance when used in cold regions, alcohol, ether and other substances are usually used as antifreeze in alcohol fuels, such as Chinese patent CN200710045098 using isopropanol as antifreeze and CN200410048043 using Ethylene glycol methyl ether is used as antifreeze additive, and CN200510127506.X adopts methanol as antifreeze agent. Because methanol antifreeze agent is poisonous and alcohol ether antifreeze agent is volatile, the evaporation loss in use is large, and needs to be supplemented at any time. Reasonable improvement of the antifreeze agent for alcohol fuels, and a production of low temperature resistant alcohol clean fuels is proposed

Embodiment 1

[0036] Embodiment 1: low temperature resistant alcohol clean fuel composition (weight ratio):

[0037] Ethanol: 15%; gasoline component oil (distilled as naphtha at 60-120°C, octane number 65, product of Daqing Fine Chemical Factory): 80%; glycerin and glycerin formal (1:1): 5% .

[0038] Its preparation method is:

[0039] Add ethanol, gasoline component oil, glycerin and glycerin formal into the reaction kettle in sequence, stir evenly to obtain a homogeneous mixture, which is low temperature resistant alcohol clean fuel.

[0040] After using the above-mentioned low-temperature-resistant alcohol clean fuel test at sub-zero temperature, it is found that it can still be used normally at -20°C.

Embodiment 2

[0041] Embodiment 2: low temperature resistant alcohol clean fuel composition (weight ratio):

[0042] Ethanol: 19%; gasoline component oil (distilled as naphtha at 60-120°C, octane number 65): 70%; combustion accelerator (composed of ethanol, acetone and hydrogen peroxide in a volume ratio of 1:1 : 1 mixed): 1%; Polyetheramine: 0.03%; Fatty acid amide aniline: 0.05%; 6-Di-tert-butylphenol: 0.8%; Isobutylamine: 0.4%; Methylcyclodiene manganese tricarbonyl: 0.3%; Glycerol formal: 4.3%; Heptanol: 0.8%; o-xylene: 2%; n-Butanol: 1%; Triacetin: 0.3%

[0043] The specific preparation process of this example is as follows:

Abstract

The invention relates to a low temperature resistant alcohol clean fuel oil, comprising 10% to 30% of ethanol, 65% to 86% of gasoline component oil and 0.01% to 5% of glycerin and / or glycerol formal; and the percentages are weight percentages. The preparation method is as follows: at normal temperature and pressure, gasoline component oil, ethanol, glycerin and / or glycerol formal are added to a reaction kettle in turn; and the required product is obtained after stirring. The invention has very good low temperature resistant effect, and can still be normally used at the temperature of -20 DEG C. Moreover, the invention has simple preparation technology, low production cost, good alcohol oil intersolubility, and difficult lay separation. The fuel in the invention can be used at low temperature, thereby not only having broad market prospect but also having important social meaning.

Description

technical field [0001] The present invention relates to low-temperature-resistant liquid fuel oil, more specifically, to a kind of green and environment-friendly alcohol blended with alcohols and gasoline component oils as main raw materials, supplemented with additives to improve performance Class clean fuel. Background technique [0002] With the rapid development of my country's national economy, the amount of social vehicles and civilian vehicles will increase rapidly, and the demand for refined oil in my country will increase day by day, starting from 1994. my country has become a net importer of oil, and the annual import volume is increasing year by year. Therefore, the search for alternative fuels has been put on the important agenda. [0003] After adding 10% ethanol to unleaded gasoline for vehicles, ethanol is completely miscible with water and partially miscible with gasoline. Therefore, when water, ethanol, and gasoline coexist, a ternary system will be formed....
