Background technology
Petroleum industry can be rated as the lifeblood of development of world economy.Along with mankind's recover petroleum year in year out; only surplus 1,500 hundred million tons of the workable reserve of conventional crude, and global crude oil annual production at present oneself reach 3,000,000,000 tons, so calculate; the day of the exhaustion of conventional oil, oneself was not very remote, and energy dilemma has become a worldwide problem.
Diesel oil is the product of a kind of oil after the petroleum refining.It is mixed by different hydrocarbon polymers and forms.Its main component is alkane, cycloalkanes or the aromatic hydrocarbons that contains 10 to 22 carbon atoms.Its chemistry and physical property are between gasoline and heavy oil, and boiling point is between 170 ℃ to 390 ℃, and proportion is 0.82 ~ 0.845kg/l.Diesel oil is widely used in oversize vehicle, ships, generator etc. at present.Main liquid fuel as diesel engine, because high-speed diesel engine (automobile is used) is more fuel-efficient than petrol motor, diesel oil demand rate of growth is greater than gasoline.Some kart even high-performing car are also used diesel oil instead at present.Though diesel oil be unlike can producing toxic gas as the gasoline, so to a certain extent than gasoline more environmental protection and health,, coming compared with gasoline, diesel oil contains more impurity, also more is easy to generate flue dust during its burning, causes atmospheric pollution.
Heavy oil is the residue mink cell focus after oil extracts gasoline, diesel oil, is characterized in that molecular weight is big, viscosity is high.The proportion of heavy oil is generally at 0.82 ~ 0.95 kg/l, and the combustiblecomponents in the heavy oil is more, and carbon containing 86%～89% is hydrogeneous 10%～12%, all the other composition nitrogen, oxygen, sulphur etc. seldom, the thermal value of heavy oil is very high, is generally 40000～42000kJ/kg.Boiler at aspects such as Iron And Steel Industry is heavy oil with combustion oil substantially at present.Because exploration, exploitation, the refining technology more complicated of heavy oil, fund input is big, and causes environmental pollution easily.
Because the high pollution of diesel oil and heavy oil, simultaneously because after the seventies in 20th century secondary oil crisis, rise of the oil price, so need take measures to use new forms of energy to substitute diesel oil and heavy oil.
Liquefied petroleum gas (LPG) is refinery resulting byproduct when carrying out crude oil catalytic pyrolysis and thermo-cracking.The major ingredient of catalytically cracked gas following (%): hydrogen 5-6. methane 10. ethane 3-5. ethene 3. propane 16-20. propylene 6-11. butane 42-46. butylene 5-6 contain the above hydro carbons 5-12 of 5 carbon atoms.The major ingredient of thermal cracking gas following (%): hydrogen 12. methane 5-7. ethane 5-7. ethene 16-8. propane 0.5. propylene 7-8. butane 0.2. butylene 4-5 contain the above hydro carbons 2～3 of 5 carbon atoms.Liquefied petroleum gas (LPG) compare with other fuel have pollution less, the thermal value advantages of higher, can gasoline replacing as automobile fuel.From 20 end of the centurys, China has built up Vehicle Fueling Station in each big and medium-sized cities in succession, substitute gasoline with liquefied petroleum gas (LPG) and make automobile fuel, the change of this fuel band, greatly purified urban air-quality, because liquefied petroleum gas (LPG) is refinery resulting byproduct when carrying out crude oil catalytic pyrolysis and thermo-cracking, this has also saved the energy to a certain extent simultaneously.
Though the octane value of liquefied petroleum gas (LPG) is about 110, it is good vehicle fuel, but vehicle power when climbing of in use finding this fuel driven is obviously not enough, adopts 90% content analysis of gasoline Engler distillation boiling range, and heavy constituent content is low in the fuel.Therefore, we need take certain measure to improve this deficiency of liquefied petroleum gas (LPG).
