Abstract
The invention belongs to the field of fuels and relates to a vehicle high-proportion methanol gasoline and a preparation method thereof. The vehicle high-proportion methanol gasoline comprises the following components in percentage by weight: 85 to 90 percent of methanol, 3 to 4 percent of solvent oil, 5 to 10 percent of No. 90 national standard gasoline and 1 to 2 percent of additive, wherein the additive is prepared by blending sodium hexadecyl sulfonate, calcium hexadecyl sulfonate, liquid naphthenic acid, methylal, nitromethane and C3-C8 monohydric alcohol. The high-proportion methanol gasoline of the invention overcomes the disadvantages of the traditional high-proportion methanol gasoline under the condition of no change of the vehicles; each index completely meets the standard of vehicle methanol gasoline M85 of 'GB/T23799-2009'; and the vehicle high-proportion methanol gasoline can be well applied to vehicles.
Description
technical field [0001] The invention belongs to the field of fuel, and in particular relates to a high-proportion methanol gasoline for vehicles, and also relates to a preparation method thereof. Background technique [0002] Energy crisis and environmental pollution are two major problems facing the world today. Therefore, actively seeking and developing clean energy and alternative energy has become a top priority for all countries in the world. Methanol has the characteristics of high oxygen content, high octane number, low environmental pollution, etc., and has a wide range of sources, so it is an ideal alternative fuel for vehicles. The currently used methanol gasoline is mainly low-ratio methanol gasoline with a methanol content below 30% and high-ratio methanol gasoline with a methanol content above 85%. The low proportion of methanol gasoline not only has a low energy substitution rate, but also has high-temperature air resistance and low-temperature stratification ...
