Problems solved by technology

There is still a serious problem in the promotion process of low-proportion methanol gasoline-high saturated vapor pressure, it is easy for the tanker to fail to add fuel in high temperature weather, it is easy to stratify at low temperature, and the inhalation of a small amount of water is also easy to cause oil stratification. can not be used

Embodiment 1

[0024] To prepare 1000 liters of high-clean motor gasoline for direct use, the volume ratio is:

[0025] Methylal 150 liters, naphtha 480 liters, aromatic oil 160 liters, mineral spirits 170 liters, MTBE 30 liters, ethylene glycol monoethyl ether 2.8 liters, ethylene glycol monobutyl ether 6.2 liters, 1,6 hexamethylenediamine 0.75 liter, N,N′-disalicylidene-1,2 propanediamine (metal deactivator T1201) 0.25 liter.

[0026] First, stir the additives in a small stirring tank at room temperature for 5-10 minutes, mix well and set aside; add the above additives into the tank containing naphtha, then add MTBE, transfer into solvent oil, and then add methylal and aromatic oil in turn , turn on the oil tank circulation device, and circulate for 5 to 10 minutes to complete the preparation work.

Embodiment 2

[0028] Methylal 170 liters, naphtha 480 liters, aromatic oil 160 liters, mineral spirits 160 liters, MTBE 20 liters, ethylene glycol monoethyl ether 3.0 liters, ethylene glycol monobutyl ether 6.0 liters, 1,6 hexamethylenediamine 0.8 1, 0.20 liters of metal passivator T1201, and the preparation method is the same as in Example 1.

Embodiment 3

[0030] Methylal 190 liters, naphtha 450 liters, aromatic oil 180 liters, mineral spirits 150 liters, MTBE 25 liters, ethylene glycol monoethyl ether 1.33 liters, ethylene glycol monobutyl ether 3.1 liters, 1,6 hexamethylenediamine 0.4 1, 0.17 liters of metal passivator T1201, and the preparation method is the same as in Example 1.

Abstract

The invention relates to a gasoline for a high cleaning vehicle, which is prepared from the following raw materials in percentage by volume: 15-20% of methylal, 40-50% of naphtha, 12-18% of aromatic oil, 1-5% of methyl tert-butyl ether, 12-18% of solvent oil or gasoline and 0.5-1% of additive. The saturated vapor pressure of the gasoline for a high cleaning vehicle meets the requirement in Chinese Standard; and the gasoline for a high cleaning vehicle has a small corrosion action on rubber parts, can not easily stratify when meeting water, and solves the technical problems existing in the low-proportion methanol gasoline at present, so that the oil product is suitable for blending, storage and transportation, and also suitable for the consumption of the vehicle in a better way.

Description

technical field [0001] The invention belongs to the technical field of alcohol ether fuel for vehicles, in particular to high-clean gasoline for vehicles containing methylal. Background technique [0002] The world's energy reserves are becoming increasingly scarce and environmental problems are becoming more and more serious. Energy and environmental issues have attracted great attention from all countries in the world. Therefore, seeking new clean alternative energy has become a global issue. my country's economy is developing at a high speed. In 2010, the output of automobiles reached 17 million, and the sales volume reached 15 million. China has become the largest automobile manufacturer and consumer in the world. By the end of 2010, the number of motor vehicles in my country has exceeded 195 million, of which the number of cars has reached 90 million, and vehicle exhaust has become the first element of environmental pollution. Since most of the oil consumed each year n...
