Problems solved by technology

Due to the relatively fixed distillation range of gasoline, it is not easy to adjust the distillation range, Reid saturated vapor pressure (RVP) and phase separation temperature of the alcohol-containing fuel prepared after blending with methanol and ethanol
The change of the engine in different regions such as altitude, atmospheric pressure, and ambient temperature will have a certain impact on various technical characteristics of the engine. In severe cases, the engine cannot run smoothly and reliably
This in turn leads to an increase in the safety factor, and through experimental research, alcohol-containing fuels must meet the conditions of the entire territory of our cou

Example Embodiment

[0033] Example 1

[0034] A method for preparing high-quality fuel oil by blending alcohol-containing fuel. The national standard fuel oil is divided into multiple fractions according to the temperature range of the distilled fraction, and alcohol-containing fuel, lubricant or combustion aid is added according to each fraction. One or both of them can be used to prepare high-quality alcohol-containing fuel oil that can avoid air resistance, enhance fuel power performance, reduce engine start-up temperature, and improve engine working conditions.

[0035] Specifically include the following steps:

[0036] (1) Take the national standard fuel oil, and perform fractionation treatment on the national standard fuel oil to obtain fractions with fractions of 30-205 °C fraction, which are ready for use;

[0037] (2) Divide the fraction of step 1) 30-205 ℃ fraction into three narrow fractions, the narrow fraction of the first stage is 30-60 ℃, and the narrow fraction of the second stag...

Example Embodiment

[0048] Example 2

[0049] On the basis of Example 1, other steps are the same as those of Example 1, specifically, the high-quality alcohol-containing fuel oil obtained by blending 40% of the second stage fraction, 40% of the third stage fraction, 5% of kerosene, and 15% of methanol, Makes the M15 methanol gasoline power and the national standard 93# no difference.

Example Embodiment

[0050]Example 3

[0051] On the basis of Example 1, other steps are the same as those in Example 1, specifically, taking 20% ​​of the second stage fraction, 40% of the third stage fraction, 10% of kerosene, and 30% of methanol to prepare high-quality alcohol-containing fuel oil , so that the power of M30 methanol gasoline can increase the maximum speed from 100㎞ / h to 130㎞ / h.

Abstract

The invention relates to the technical field of automobile fuels, and in particular relates to a method for preparing a high-quality fuel oil blended with an alcohol-containing fuel. The method comprises the following steps: carrying out distillate segmentation on the fuel oil so as to segment the fuel oil into multiple segments; aiming at solving the technical problems of an automobile engine or an engine according to a distillate at each segment, adding other lubricants, combustion improvers and power changing agents into the fuel oil while the alcohol-containing fuel is added into the fuel oil. Thus, compared with the traditional fuel oil, according to the prepared fuel oil provided by the invention, the gas resistance avoidance, a cold start temperature and the operating performance of the automobile engine are greatly improved. As a result, the obvious effects are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile oil, in particular to a method for preparing high-quality fuel oil by blending alcohol-containing fuel. Background technique [0002] The sales of low-proportion alcohol-containing fuels in my country's oil market continue to expand, and high-proportion alcohol-containing fuels have entered the experimental promotion stage. Currently alcohol-containing fuels are blended with national standard gasoline with a distillation range of 30°C to 205°C. Since the distillation range of gasoline is relatively fixed, it is not easy to adjust the distillation range, Reid saturated vapor pressure (RVP) and phase separation temperature of the alcohol-containing fuel prepared after blending with methanol and ethanol. Variations of the engine in different areas such as altitude, atmospheric pressure, and ambient temperature will have a certain impact on various technical characteristics of the engine. In sever...
