an alcohol-based fuel oil

technical field

The invention relates to an alcohol-based fuel oil, which is suitable for use as fuel in canteens, furnaces, industrial boilers and various burners of various large-scale catering enterprises, and belongs to the technical field of fuel processing.

Background technique

At present, oil resources are becoming increasingly tense and prices are rising, and there are indications that the era of low oil prices may be gone forever. In order to alleviate the shortage of oil supply and environmental pollution, a wave of renewable energy for the purpose of replacing petroleum energy has been triggered. From fuel ethanol to photovoltaic solar energy to biodiesel, all major countries in the world have received keen attention. In view of the tight supply of petroleum and fuel oil and the huge market demand, the development of safe, efficient, clean and environmentally friendly high-quality alternative fuels has become an inevitable trend in the development of new energy.

Alcohol-based fuel is a clean renewable energy source and a high-quality substitute for petroleum fuel. Vigorously developing alcohol-based fuel is of great significance to sustainable economic development, promoting energy substitution, ensuring energy security, reducing environmental pressure, and controlling urban air pollution. As early as in the development outline of the "Tenth Five-Year Plan", the country has clearly proposed the development of various petroleum substitute products, and determined the development of biological liquid fuels as an important direction for the country's production and income development. At present, most alcohol-based fuels have problems such as high manufacturing cost, high corrosion, poor mutual solubility, low calorific value, and poor swelling, so it is difficult to compete with petroleum fuels.

It has low bromine value, low content of unsaturated hydrocarbons and good stability; Reduces toxicity and fire hazards, and is conducive to safety features. The role of paraffin oil is: paraffin oil, also known as mineral oil, is a colorless and odorless mixture obtained from fractional distillation of crude oil. It has a high flash point and increases the combustion calorific value of methanol. The function of glycerin is: it has the function of combustion-supporting and flame-resistant, it can also increase the combustion calorific value of methanol, and it can increase the explosive combustion in the initial stage of ignition. Glycerin and water have relatively high boiling points and flash points. When added to methanol solution, they will form interpartition hydrogen bonds with methanol, thereby inhibiting the volatilization of methanol and increasing the flash point.

The preparation method of the alcohol-based fuel oil of the present invention: add methanol, xylene, No. 200 solvent oil, paraffin oil, glycerin, and water into a reaction kettle in sequence, and stir evenly to obtain the alcohol-based fuel oil.
