Description
Technical field
The present invention relates to additive, relate in particular to a kind of additive that is used as the liquefied petroleum gas (LPG) that contains a certain amount of alkene of automobile fuel as the liquefied petroleum gas (LPG) of automobile fuel.
Background technology
China has used liquefied petroleum gas (LPG) as automobile fuel in many big or middle cities, and this pollutes alleviating motor vehicle exhaust, improves city environmental quality, has active effect.Liquefied petroleum gas (LPG) as automobile fuel, should be satisfied automobile and drives stability, and handiness does not have corrosion to trolley part, can not produce requirements such as wearing and tearing.External Vehicular liquefied petroleum gas is mainly derived from oil-gas field.Because of wherein mainly containing saturated C
3-C
4Hydro carbons can not produce problems such as polymerization, coking.China's liquefied petroleum gas (LPG) is mainly derived from the splitting gas of refinery and ethylene plant, wherein contains a considerable amount of unsaturated olefins, directly causes fault easily as automobile fuel.Therefore should adopt physics or chemical process to handle in advance, to satisfy automobile-used requirement.
Solution to the problems described above has three kinds now.The one, with the alkane gas that oil-gas field is produced, its quality is good, but resource-constrained; The 2nd, remove wherein unsaturated olefin by alkene oligomerization technology, but the cost height; The 3rd, with the higher liquefied petroleum gas (LPG) of olefin(e) centent of productions such as refinery, directly as automobile fuel, cost is low, resource is near etc., but alkene wherein is easily polymerization under automobile-used condition, causes the nozzle of motor car engine and valve deposits, coking, makes degradation under the automobile dynamic quality.In addition, liquefied petroleum gas (LPG) wherein contains the residue of the tar character of trace when using, and time length can make the magnetic valve in the automobile fuel gas system, the flap of steam raising device bond malfunctioning.Especially winter, the automotive ignition difficulty, vaporizer stops up, and degradation is more outstanding under the dynamic performance, needs the coking one of cleaning carbon deposit inferior, and influences the normal operation of car in 1-2 month.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of and prevent, alleviate car engine machine nozzle, valve deposits coking, the flap of the magnetic valve of firing system, steam raising device is bonded malfunctioning etc., reduce the coke cleaning number of times, improve the additive of the automobile in automobilism cycle with liquefied petroleum gas (LPG).
The objective of the invention is to be achieved by following technical scheme.
A kind of automobile additive of liquefied petroleum gas (LPG) is characterized in that it is to be made by the following weight proportion raw material:
