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.

Abstract

The invention relates to a preparation method of efficient composite alcohol-based fuel. Methanol, concentrated sulfuric acid and levulinic acid are sequentially added to a reaction vessel with a condensation recovery device, and the materials in the reaction vessel are heated to 65-70 DEG C for reaction for 6-8 h; products in the reaction vessel are performed an impurity removing process to obtain a premixture containing methyl levulinate and methanol; and the premixture and veratrole are mixed and uniformly stirred to prepare the finished product. The preparation method uses the levulinic acid and methanol to be converted into and synthesize the methyl levulinate, then optimizes the impurity removing process of the methyl levulinate, and so the impurity removing process of the methyl levulinate can be achieved without rectification. Compared with a fuel evaporation rate of direct combustion of methanol, the fuel evaporation rate of the composite alcohol-based fuel of the invention isreduced by 67%. Therefore, the fuel utilization rate is high, and the combustion effect is good.

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...
