Embodiment 1

[0022] (1) 65 parts by weight of pentane

[0023] (2) 30 parts by weight of aromatic hydrocarbons (mixed toluene)

[0024] (3) 5 parts by weight of dimethyl carbonate (DMC)

[0025] (4)(CF 3 ) 2 CF(CF 2 ) 6 CH 2 CH(OH)CH 2 N + (CH 3 ) 3 I - 0.006 parts by weight

[0026] In the operation mode of the formula, the components (1), (2), (3) and (4) are jointly prepared to form a light hydrocarbon fuel product for vehicles with an octane number (RON)>93.

[0027] In the formulation of this example, component (4) is a fluorine-containing alkylamine quaternary ammonium salt type cationic fluorocarbon surfactant, which can also be used as a perfluoroalkylamide quaternary ammonium salt type cationic fluorocarbon surfactant agent, such as C 7 f 15 CONH(CH 2 ) 3 N + (CH 3 ) 3 I - ; Or fluoroalkylamine salt type cationic fluorocarbon surfactant, such as [F(CF 2 ) 8 CH(OH)CH 2 〕 2 NCH 2 CH 2 NH 2 .H 2 SO 4 .

Embodiment 2

[0029] (1) 58 parts by weight of pentane

[0030] (2) 35 parts by weight of toluene

[0031] (3) 7 parts by weight of dimethyl carbonate (DMC)

[0032] (4)C 7 f 15 CONH(CH 2 ) 3 N + (CH 3 ) 3 I - 0.006 parts by weight

[0033] The operation mode of the formula in this example is the same as that of the first example above, and the components (1), (2), (3), and (4) are jointly formulated into light hydrocarbons for vehicles with an octane number (RON) > 90 Fuel product, in the formula of this embodiment, component (4) is a kind of perfluoroalkylamide quaternary ammonium salt type cationic fluorocarbon surfactant, it can also use fluorine-containing alkylamine quaternary ammonium salt type cationic instead Fluorocarbon surfactant [with reference to the component (4) of the aforementioned first embodiment formula], perhaps, use fluoroalkylamine salt type cationic fluorocarbon surfactant instead, such as [F(CF 2 ) 8 CH(OH)CH 2 〕 2 NCH 2 CH 2 NH 2 .H 2 SO 4 . ...

Embodiment 3

[0035] (1) 70 parts by weight of pentane

[0036] (2) 25 parts by weight of xylene

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...
