一种甲醇车用M100甲醇燃料母液添加剂及其制备方法A kind of methanol vehicle M100 methanol fuel mother liquor additive and preparation method thereof

技术领域technical field

本发明涉及车用燃料技术领域，特别涉及一种甲醇车用M100甲醇燃料母液添加剂及其制备方法。The invention relates to the technical field of vehicle fuels, in particular to a methanol vehicle M100 methanol fuel mother liquor additive and a preparation method thereof.

背景技术Background technique

目前大部分汽车仍以汽油等作为燃料，而只有少部分以甲醇作为燃料，以甲醇燃料为主的汽车通常称为甲醇汽车，随着甲醇汽车逐渐走向市场，国内的甲醇汽车已形成一定规模。At present, most of the vehicles still use gasoline as fuel, and only a small number of them use methanol as fuel. Vehicles mainly fueled by methanol are usually called methanol vehicles. As methanol vehicles gradually enter the market, domestic methanol vehicles have formed a certain scale.

现有常见的为M85，即，以85％甲醇与15％汽油混合作为燃料。在研发M100甲醇车用的燃料中，除甲醇基料成分外，往往需要添加较高占比的添加剂，而甲醇燃料的添加剂在燃料成品中的占比越高，及其所选原料固体原料占比越大，则对产品在生产工艺、配制时间、设备选型等等方面的生产成本大大增加，而且大汽污染物排放越多，车辆长时间应用损害越大。而且由于技术水平受限，目前的甲醇燃料添加剂在配制甲醇燃料产品中，常存在排放不完全，积碳量大，易使车辆缸体及其他部件使用寿命减少，喷油嘴易坏，易熄火等不足；其配制的甲醇燃料稳定性差和动力不足，不能长期保存，出现分层及热值变化，甚至动力不足，提速慢，醇耗量大大增加等问题，从而导致现有的甲醇汽车的经济性降低，市场竞争力较低，不利于甲醇汽车以及甲醇车用燃料的推广实施，因此，研发一种低占比、高稳定性和动力的甲醇燃料母液添加剂，使之更好地应用于甲醇车用的甲醇燃料中，绿色环保，有利于促进甲醇汽车及车用燃料的更广泛的推广。The most common one is M85, that is, 85% methanol mixed with 15% gasoline as fuel. In the research and development of M100 methanol vehicle fuel, in addition to the methanol base material, it is often necessary to add a relatively high proportion of additives, and the proportion of methanol fuel additives in the finished fuel is higher, and the selected raw material solid raw materials account for a higher proportion of the fuel. The larger the ratio, the greater the production cost of the product in terms of production process, preparation time, equipment selection, etc., and the more atmospheric pollutants are emitted, the greater the damage to the vehicle for a long time. Moreover, due to the limited technical level, the current methanol fuel additives often have incomplete emissions and large carbon deposits in the preparation of methanol fuel products, which is easy to reduce the service life of the vehicle cylinder block and other components, and the fuel injector is easily damaged and easy to flame out. and other deficiencies; the methanol fuel prepared by it has poor stability and insufficient power, cannot be stored for a long time, has stratification and changes in calorific value, even insufficient power, slow speed increase, and greatly increased alcohol consumption, etc., which lead to the economy of existing methanol vehicles. It is not conducive to the promotion and implementation of methanol vehicles and methanol vehicle fuels. Therefore, a methanol fuel mother liquor additive with low proportion, high stability and power is developed to make it better applied to methanol. Among the methanol fuels for vehicles, it is green and environmentally friendly, which is conducive to promoting the wider promotion of methanol vehicles and vehicle fuels.
