Problems solved by technology

Second, environmental pollution
According to its technical characteristics, the added tert-butanol and Tween-20 or Tween-80 solve the problem of poor compatibility of methanol gasoline, but Tween, as a commonly used surfactant, is expensive and the use conditions are relatively relatively Harsh, reducing the economy of this invention; using sulfonated oil, introducing sulfur molecules, although reducing the emissions of CO and HC, however, SO x The emissions are more harmful, and the three-way catalytic converter will be damaged first
In addition, the methanol gasoline described in this invention, from the component analysis, the cold start performance is definitely not good

Embodiment 1

[0019] Prepare 20kg of methanol, 75kg of 90# gasoline, 1kg of cosolvent isopropyl ether, 2kg of combustion enhancer isoheptanol; 1.99kg of ethanolamine; 0.01kg of benzotriazole. The preparation process is as follows: first put methanol in the batching tank, then add a cosolvent, add a combustion aid and an antiseptic under stirring, and finally add a metal deactivator and gasoline. Self-circulation three times and standing for 40 minutes to obtain alcohol ether fuel.

[0020] This alcohol ether fuel has good cold start performance and good stability.

Embodiment 2

[0022] Prepare 34kg of methanol, 60kg of 90# gasoline, 4kg of methyl formate as a cosolvent, 1.5kg of isoheptanol as a combustion aid, 0.01kg of triethylamine, and 0.49kg of benzotriazole. The preparation process is as follows: first put gasoline in the batching tank, then add a cosolvent, add a combustion aid and an antiseptic under stirring, and finally add a metal deactivator and methanol. Self-circulation three times and standing for 40 minutes to obtain alcohol ether fuel.

[0023] Compared with ordinary gasoline, this alcohol ether fuel has lower fuel consumption.

Embodiment 3

[0025] Prepare methanol 50kg, 90# gasoline 42.5kg, cosolvent dimethyl ether 4kg, combustion enhancer isobutanol 3kg; diethanolamine 0.2kg; benzotriazole 0.3kg. The preparation process is as follows: first put methanol in the batching tank, then add a cosolvent, add a combustion aid and an antiseptic under stirring, and finally add a metal deactivator and gasoline. Self-circulation three times and standing for 40 minutes to obtain alcohol ether fuel.

[0026] This alcohol ether fuel has good stability and low fuel consumption.

Abstract

The invention relates the alcohol ether fuel and preparing method. The fuel comprises 20-80wt% methyl alcohol or ethanol, 14-75% petrol, 1-5% auxiliary solvent, 1.5-3wt% combustion adjuvant, 0.01-2wt% corrosion inhibitor, and 0.01-0.5wt% metal deactivator. The invention has the advantages of reducing energy consumption, good stable stability, good burning effect, good cold-starting, reducing the output volume of CO and HC, reducing CO content, simple technology and low cost.

Description

technical field [0001] The invention relates to the field of alcohol ether fuel and its preparation method. Background technique [0002] The world is currently facing two major problems, one is the oil energy crisis. Relevant data show that the world's proven oil reserves are 142.1 billion tons, and based on the average annual production of 3.56 billion tons in the past 10 years, it can be used for 39.9 years. my country's oil reserves are limited, and the proven oil reserves can only be exploited for about 20 years. Since 1993, China has become a net importer of oil. In 2000, the oil import volume was 70 million tons. In 2002, the daily oil consumption reached 5.01 million barrels, surpassing Japan and becoming the world's second largest oil consumer after the United States. More than 60% of China's oil depends on imports, becoming the world's most important buyer of oil. If China's modernization is based on oil imports, energy security and national security will be gr...
