Pentane (C ₅H ₁₂) product output when being cracking of oil between 40-70 ℃ is about 2,800,000 tons/year, is liquid, transparent, tasteless, nontoxic at normal temperatures and pressures.Most of oil refinery is not separated it, and a part is listed gasoline group industry in No. 70, and a part has arrived liquefied petroleum gas (LPG) group industry.Major part is burnt by the oil refinery smokestack.Pentane has arrived in the liquefied petroleum bottle, can't gasify and release burning, to a certain amount of, extract raffinate out, the grievous injury user.Pentane has arrived in the gasoline, because its boiling point is low than other compositions of gasoline, is easy to form vapour lock in the Carburetor of automobile.Even therefore the shadow that also has vapour lock in the spray-type fuel oil device, can't utilize the eleventh of the twelve Earthly Branches alkane to hindering normal fuel delivery always.

Octane value is an agreement numerical value of expression spark-ignition engine antiknock quality, and according to non-lead gasoline for car specification and standard, No. 90 octane number RON is 90, No. 93 octane number RON is 93, present employed engine compression ratio, for reaching the purpose of antiknock, the octane number RON that requires to use is between 90-93, propane RON105.7 in the liquefied petroleum gas (LPG), butane RON93.6, isobutane RON101, and pentane RON61.7, isopentane 92.3, neopentane RON85.5.As seen the pentane octane value is on the low side, but can add the octane value that methyl tertiary butyl ether(MTBE) (MTBE) and tert-butyl alcohol oxycompounds such as (TBA) improve pentane.

The present invention has following advantage compared to existing technology:

1, Security is good

Pentane in the time of 60 ℃, its saturation vapor pressure 0.212Mpa, 0.383Mpa in the time of 80 ℃, in the time of 100 ℃, 0.583Mpa, steel cylinder needn't be thickeied, and can use safely, even catch fire can explosion yet in the outside.36.2 ℃ of the boiling points of pentane overflow ground and are in a liquid state, and evaporation rate is very slow, and its concentration of catching fire is 1.4-7.8, and is similar with liquefied petroleum gas (LPG), but because its evaporation is slow, are not taken away by moving air before reaching the concentration of catching fire.And its burning comprises evaporation, mixing, burning three phases, and ignition energy requires high, and velocity of combustion is slow.Electrostatic pressure is greater than just lighting more than 10000 volts.

2, good economy performance

The pentane lower calorific value is 37000Kcnl/m ³, exceed more than 40% than liquefied petroleum gas (LPG).The engine power higher than liquefied petroleum gas (LPG) not only is provided, and brings economic benefits.Domestic aboundresources, price steadiness.2.2 yuan/liter in No. 90 gasoline in market are got 0.78 kilogram/liter of gasoline gravity, and then gasoline is 2.82 yuan/kilogram, and pentane is 1.5-2.1 unit/kilogram then.The regular price gasoline tank car can load and transport in addition, and accumulating is convenient, and cost is low, can efficient height.

3, spatter property is good

Because the pentane carbon content is lacked than gasoline, diesel oil.And pentane does not contain H ₂S, the ash impurity that grades.During burning, can adjust gas concentration, guarantee the requirement and the automobile running working condition coupling of coefficient of excess air, reduce the discharging of CO and HC at device.

4, can is convenient

Because pentane is liquid at normal temperatures and pressures, therefore can in each gas station inside and outside the city, store and can, the available electron nozzle also can be irritated 56.7 liters (12.3 gallons made in Great Britain) only 1.4 minutes with the rapid pipe joint of band hydraulic lock.Also underground storage can be set in the public transport parking lot, refuel nearby.

5, rational in infrastructure, energy-efficient, reliable operation is easy to popularize, and recondition expense is lower than the automobile of repacking liquefied petroleum gas set.
