Abstract

The invention relates to the field of ethanol fuel oil, in particular to an ethanol fuel oil additive with a high oxygen content and a preparation method thereof. The preparation method for the ethanol fuel oil additive with the high oxygen content comprises the following steps: dissolving 1,2,3-trihydroxybenzene in absolute ethyl alcohol to obtain an ethanol solution of 1,2,3-trihydroxybenzene; adding potassium hydroxide powder into the ethanol solution of 1,2,3-trihydroxybenzene to obtain a solution A; sealing the solution A, and then introducing excessive pure oxygen into the solution A toenable the solution A to be fully adsorbed so as to obtain a solution B; and adding calcium oxide into the solution B, carrying out dehydrating for 24-30 hours, and performing filtering to obtain theethanol fuel additive. According to the invention, 1,2,3-trihydroxybenzene absorbs oxygen to form high-oxygen-concentration liquid, so aerobic combustion of gasoline can be effectively promoted in theprocess of combustion, and carbonization of organic matters in the gasoline is inhibited.

Description

technical field [0001] The invention relates to the field of ethanol fuel, in particular to an ethanol fuel additive with high oxygen content and a preparation method. Background technique [0002] With the continuous development of the economy, the consumption of fossil energy such as gasoline is increasing year by year, and reducing the dependence on non-renewable energy is a necessary factor for establishing a sustainable development society. Ethanol gasoline is the addition of 10% ethanol to traditional gasoline as vehicle fuel, which can not only alleviate the dependence on petroleum resources, but also digest a large amount of old grain and promote the development of agriculture. The use of ethanol gasoline can greatly reduce CO emissions in vehicle exhaust, improve air quality and alleviate environmental pollution. [0003] Ethanol gasoline also has many disadvantages, such as low combustion calorific value, swelling of rubber, and corrosion of pipes by products. On...
