preparation example Construction

[0025] As described above, the preparation method of boiler alcohol-based fuel comprises the following steps:

[0026] (1) Remove part of the water from industrial fusel alcohols through molecular sieves;

[0027] (2) Add sodium bicarbonate and sodium carbonate to the fusel alcohol obtained in step (1) at the same time, and stir at room temperature for 20-30 minutes;

[0028] (3) Add methanol to the resultant in step (2) while stirring to make it evenly mixed;

[0029] (4) Add hydrogen peroxide to the product obtained in step (3), stir at room temperature to mix evenly, and then the boiler alcohol-based fuel can be prepared.

[0030] In order to better understand the present invention, the present invention will be further described through the following examples, but the content of the present invention is not limited thereto.

Abstract

The invention discloses an economical and environment-friendly boiler alcohol-based fuel, which is prepared from the following raw materials in percentage by mass: 50-80% of fusel, 20-50% of methanol,1-3% of hydrogen peroxide, 0.15-0.26% of sodium carbonate and 0.02-0.05% of sodium bicarbonate. The used main raw materials contain more high-calorific-value organic matters and are low in price; after hydrogen peroxide is added, the combustion can be more sufficient, and the emission after combustion has a single component and is more environment-friendly; all used materials are low in cost andeasy to obtain; the preparation process is simple, the input cost is low, and the operability and generalization performance are high.

Description

technical field [0001] The invention belongs to the technical field of fuel oil, and in particular relates to an economical and environment-friendly boiler alcohol-based fuel for efficient utilization of industrial fusel alcohols and a preparation method thereof. Background technique [0002] On the one hand, as the country and localities pay more and more attention to environmental protection, the demolition and modification of coal-fired boilers have been implemented in many places. Alcohol-based boiler fuels with methanol as the main fuel are developing rapidly, but limited by the price of methanol, mostly small and medium-sized private enterprises with little income, and the current high operating costs of alcohol-based fuels on the market, resulting in the actual promotion of alcohol-based boiler fuels. Boiler fuel is in trouble. On the other hand, fusel alcohols produced in industrial fields such as coal-to-oil and coal-to-methanol are treated as hazardous waste, and ...
