Embodiment 1

[0037] Embodiment 1 single transesterification reaction

[0038] Respectively transesterify dimethyl carbonate (or ethylene carbonate) and a monohydric alcohol with 2-8 carbon atoms in a tubular transesterification reactor, using zinc acetate as a catalyst, zinc acetate and dimethyl carbonate The weight ratio of ester or ethylene carbonate is (0.1-1): 100, the molar ratio of dimethyl carbonate (or ethylene carbonate) to monohydric alcohol is controlled at 1:2-8, and the reaction temperature is 140-200°C, absolutely The pressure is 2-8MPa, the reaction time is 10-20 minutes, and the dialkyl carbonate mixture is obtained;

[0039] The dialkyl carbonate mixture is distilled under reduced pressure at an absolute pressure of 0.01-0.02MPa and a temperature of 180-200°C, and the corresponding fractions are collected to obtain dicarbonates with different carbon numbers with a volume content of ≥95%. Alkyl esters.

Embodiment 2

[0040] Embodiment 2 mixed transesterification reaction

[0041] After mixing dimethyl carbonate (or ethylene carbonate) with various monohydric alcohols with 2-8 carbon atoms, transesterification is carried out in a tubular transesterification reactor, and other transesterification conditions are the same as in Example 1;

[0042] The dialkyl carbonate mixture is distilled under reduced pressure at an absolute pressure of 0.01-0.02MPa and a temperature of 180-200°C, and the fraction at 80-90°C is collected to obtain a dialkyl carbonate mixture with a carbon number of ≤5 ;Collect the distillate at 125-135°C to obtain a dialkyl carbonate mixture with 6-9 carbon atoms; collect the distillate at 180-200°C to obtain a dialkyl carbonate mixture with 10-17 carbon atoms .

Embodiment 3

[0043] Embodiment 3 deploys gasoline

[0044] According to the method described in Example 1, ethyl methyl carbonate, diethyl carbonate, dipropyl carbonate and dibutyl carbonate with volume content ≥ 95% were prepared respectively (ordinary commercially available dialkyl carbonate can also be directly used) , mixed and blended into 3-1 and 3-2 gasoline according to the composition in Table 1;

[0045] According to the method described in Example 2, dimethyl carbonate (or ethylene carbonate) was mixed with ethanol, n-propanol and n-butanol and then transesterified to obtain carbon atoms with a carbon number of ≤ 5 and a carbon number of 6 respectively. -9 and dialkyl carbonate mixtures with 10-17 carbon atoms are mixed and formulated into 3-3 and 3-4 gasoline according to the volume percentage in Table 1;

[0046] See Table 2 for the quality detection results of the blended gasoline prepared by the present invention.

[0047] Table 1 Composition and volume content of blended ...

Abstract

The invention discloses liquid fuel. The component of the liquid fuel comprises dialkyl carbonate with the molecular formula of CnH2n+1-[OCOO]-CmH2m+1, wherein the n is not smaller than 1 and is not greater than 8, and the m is not smaller than 2 and is not greater than 8. The liquid fuel disclosed by the invention has the characteristics of no toxin and biological degradation, has the advantages of traditional fossil-based and biological liquid fuel simultaneously, is better than fossil-based liquid fuel in the aspects of the lubricating property, the discharging property, the noise reducing property, the volatility, the safety, the environment-friendly property and the like and is better than biological liquid fuel in the aspects of the low-temperature property, the compatibility of a sealing material, the heat and oxidation stability, the corrosiveness, the price and the like. The liquid fuel disclosed by the invention has high comprehensive performance-price ratio, exceeds traditional liquid fuel in an omnibearing way in functions and can be widely used for the fuel of a motor vehicle, the fuel of weaponry and equipment, fuel for cooking, central heating and the like, fuel for power generation, fuel for an extremely harsh requirement to a working condition, fuel for a high requirement to environmental protection and fuel for a high requirement to the healthy safety.

Description

technical field [0001] The invention relates to a liquid fuel, in particular to an environment-friendly liquid fuel and a preparation method thereof. Background technique [0002] Fuel can be divided into solid fuel, liquid fuel and gaseous fuel according to form; it can be divided into fossil fuel, biofuel and nuclear fuel according to type. Liquid fuels include crude oil and petroleum products, light diesel oil, heavy oil, gasoline, kerosene, coal tar, shale oil, synthetic oil products, coal liquefied oil, alcohol fuels and other liquid fuels. [0003] With the rapid development of the world's economy and society, the demand for energy is also increasing, and energy issues have attracted more and more attention from all sides. Although fossil energy is still in a dominant position at present, massive mining has led to the depletion of fossil fuel resources such as coal, oil and natural gas. Since the 1990s, driven by the goals of promoting agricultural development, ensur...
