Abstract

The present invention is one kind of alcohol-hydrocarbon fuel with high octane number for vehicle. The alcohol-hydrocarbon fuel consists of light hydrocarbon 100 weight portions, anhydrous methanol or anhydrous ethanol 3-30 weight portions, propane 10-25 weight portions, toluene or xylene 5-25 weight portions, cosolvent 0-10 weight portions and cationic fluorocarbon surfactant 0.004-0.04 weight portion. The present invention is one kind of clean automobile fuel with high octane number 95-97, low cost, no corrosion high abrasion resistance and environment friendship. The alcohol-hydrocarbon fuel is suitable for use in LPG liquid jetting automobile with high compression ratio.

Description

technical field [0001] The present invention relates to a kind of vehicle fuel, more specifically, the present invention relates to a kind of high-octane value vehicle fuel containing petrochemical refinery by-product light hydrocarbon (butane, pentane, hexane mixed hydrocarbon) and alcohols . Background technique [0002] Alcohols, such as methanol, have an oxygen molecular content of up to 50% (gasoline oxygen molecular content is 0), a burning speed of 52 m / s (M / S) (gasoline 38M / S), and the combustion calorific value of methanol is only half that of gasoline. Hydrocarbons (hydrocarbons, aromatic fuels) are mixed and burned in the cylinder. Due to the fast combustion rate of methanol, the average effective pressure of the engine cylinder is higher than that of gasoline. Therefore, with the same amount, the car runs the same distance as gasoline. Methanol is a product of coal and natural gas. 1 ton of methanol can be produced from 1.5 to 1.8 tons of coal, and the cost is m...
