Abstract

The invention discloses a vehicle light hydrocarbon fuel containing methyl-carbonate and the components comprise 100 weight portions of light hydrocarbon, 5 to 46 weight portions of aromatic hydrocarbon, 1 to 11 weight portions of di methyl carbonate (DMC) and 0.004 to 0.4 weight portion of positive ion perfluorocarbon surface active agent. The product of the invention is the vehicle fuel which has high research octane number (RON) of 90 to 95, low cost, good environmental effect, no corrosion and good abrasion resistance.

Description

technical field [0001] The invention relates to a light hydrocarbon fuel for vehicles. Background technique [0002] Alcohol ether substances, oxygen molecular content: 50 for methanol, 35 for ethanol, and 18 for methyl tert-butyl ether. Oxygenated compounds are excellent gasoline antiknock agents, which can significantly increase the octane number of gasoline, but they all have certain side effects . For example: Methanol is poisonous, swells rubber, has strong water absorption, corrodes pipes, damages fuel pumps, and its calorific value is only 1 / 2 of that of gasoline. A large amount of formaldehyde is generated in combustion exhaust, which endangers human health. MTBE (methyl tert-butyl ether) is non-toxic, but it pollutes groundwater quality. It has been eliminated in the United States, and ethanol is used as an antiknock agent. MTBE and ethanol have low calorific value. To achieve the oxygen content of 2.7% (weight fraction) in gasoline, it is necessary to add 15% (vo...
