Problems solved by technology

[0004] In alcohol-based fuels, during the combustion process of methanol, due to its very low boiling point, direct combustion will cause part of the methanol to gasify, resulting in a large amount of waste, and the loss of fuel is very high
Moreover, if methanol vapor is inhaled by the human body in large quantities, it will also have an impact on human health.

[0020] Step 2, dehydrating the product inside the reactor with water-absorbent resin to obtain a mixed solution, then adding anhydrous barium chloride to the mixed solution and stirring to generate a mixture containing precipitation, the mass ratio of the mixed solution to anhydrous barium chloride is 70:7; the mixture containing the precipitate is filtered with filter paper to remove the precipitate to obtain a premix, which contains methyl levulinate and methanol;

[0021] Step 3, mixing and stirring the premix and veratrole according to the mass ratio of 100:28 to obtain the finished product.

Embodiment 3

[0023] Step 1. Add 1170 parts by mass of methanol, 9.8 parts by mass of concentrated sulfuric acid with a mass fraction of 98%, and levulinic acid of 120 parts by mass in the reaction kettle with a condensation recovery device, and heat the materials in the reaction kettle to 65 ~ Reaction at 70°C for 8h. The yield of methyl levulinate was 63.7%.

[0024] Step 2, dehydrating the product inside the reactor with water-absorbent resin to obtain a mixed solution, then adding anhydrous barium chloride to the mixed solution and stirring to generate a mixture containing precipitation, the mass ratio of the mixed solution to anhydrous barium chloride is 130:7.5; the mixture containing the precipitate was filtered with a filter paper to remove the precipitate to obtain a premix, which contained methyl levulinate and methanol.

[0025] Step 3, mixing and stirring the premix and veratrole according to the mass ratio of 100:29 to obtain the finished product.

Abstract

The invention relates to a method for preparing a high-efficiency composite alcohol-based fuel. Methanol, concentrated sulfuric acid and levulinic acid are sequentially poured into a reactor with a condensation recovery device, and the materials inside the reactor are heated to 65-70°C for 6-8 hours; The product inside the reaction kettle is subjected to an impurity removal process to obtain a premix containing methyl levulinate and methanol; the premix and veratrole are mixed and stirred evenly to obtain a finished product. The present invention utilizes levulinic acid and methanol to synthesize and convert into methyl levulinate, and then optimizes the impurity removal process of methyl levulinate, so that the impurity removal of methyl levulinate can be achieved without rectification means; compared to direct For burning methanol, the fuel evaporation rate of the complex alcohol-based fuel of the present invention is reduced by 67%. High fuel utilization rate and good combustion effect.

Description

technical field [0001] The invention relates to the technical field of alcohol-based fuels, in particular to a preparation method of high-efficiency composite alcohol-based fuels. Background technique [0002] Alcohol-based fuel is a fuel mainly composed of alcohols (such as methanol, ethanol, butanol, etc.). The combustion value of biofuel is lower than that of liquefied petroleum gas and diesel, but the price is more advantageous. It can be used as an alternative fuel for petroleum liquefied petroleum gas and fuel diesel. It is low-cost, safe and convenient. It has no residue residue, no black bottom, and is clean, hygienic and safe , cheap, easy to buy raw materials, easy to use, etc., the cost is only about one-third of the wholesale price of petroleum liquefied gas or diesel, huge profit margins, and extremely high investment value. [0003] As an important platform compound in the process of biomass conversion, methyl levulinate is widely used as food additives, spice...
