Chemistry In general, the sulfur content of petroleum fractions to increase the boiling point of the substance in the oil. Thus the fraction of diesel contains a higher percentage of sulfur than gasoline. The presence of sulfur in diesel combustion gives rise to oxides and acid corrosive and harmful to living beings. One of the most important derivative is Liquefied Petroleum Gas (LPG), consisting primarily of propane and butane. It is the alternative fuel with the greatest potential for reducing the emission of greenhouse gases producers. The fraction of propane-butane is sold in bottles for home use. Kerosene is a fraction of hydrocarbons containing from 10 to 16 carbon atoms, with a boiling point ranging from 150 ° C to 300 ° C. Its main use is as a fuel for jet aircraft. ASPHALT: is a mixture of paraffinic hydrocarbons, aromatic and heterocyclic compounds obtained from the residue of petroleum distillation. This mixture of solids with a high boiling point which are the asphalt is used in roofing and waterproofing hulls of boats and road construction. Most of the oil obtained in the distillation of petroleum (gasoline, diesel and kerosene) is intended for supplying of thousands of vehicles that use internal combustion engine. When these fuels are burned produce large amount of gases inducers (promoting) the greenhouse. See the example the combustion of petrol below: Some experts say that if the world oil consumption to continue at the current pace, the known and exploitable reserves will be exhausted by mid-century. And then? What happens if we have more oil? Already there are candidates to replace oil! The larger subs titutos gasoline are: alcohols (methanol and ethanol), natural gas (me thane) and hydrogen gas, known as "fuel of the future" In this sense, the Brazilian government in order to partially replace gasoline with alcohol - fuel, the addition of an established amount of about 25% alcohol (ethanol) to gasoline. Today we have our roads circling the cars manufactured in the '80s, the engines work only with hydrated alcohol, recent models of cars to gasoline (which actually use the blend gasoline / alcohol), the biofuels (which run on both fuels in any ratio) and vehicles powered by natural gas CNG. Have you noticed that often the petrol cars lose your income? Fuel. What's the Best?

Kemija Općenito, sadržaj sumpora u naftnim frakcijama povećati vrelište tvari u ulju. Tako je udio dizela sadrži veći postotak sumpora nego benzina. Prisutnost sumpora u dizelskim izgaranja rađa oksida i agresivnih kiselina i štetni za živim bićima. Jedan od najvažnijih derivata na ukapljeni naftni plin (UNP), koji se sastoji uglavnom od propana i butana. To je alternativno gorivo s najvećim potencijalom za smanjenje emisije stakleničkih plinova proizvođača. Dio propan-butan se prodaje u bocama za kućnu uporabu. Kerozin je dio ugljikovodika koji sadrže od 10 do 16 atoma ugljika, s vrelištem u rasponu od 150 ° C do 300 ° C. Njegov glavni koristiti je kao gorivo za mlazne zrakoplove. Asfalt: je mješavina parafinskih ugljikovodika, aromatskih i heterocikličkih spojeva dobivenih iz ostatka nafte destilacijom. Ova mješavina čvrstih tvari s visokim vrelišta koje su asfalt se koristi u krovnih hidroizolacija i trupova brodova i cestogradnji. Većina ulja dobivenog u destilacijom nafte (benzin, dizel i kerozin) namijenjen je za opskrbu tisuća vozila koja koriste motora s unutarnjim izgaranjem. Kad ti goriva izgaraju proizvoditi velike količine plinova induktorima (promicanje) staklenika. Vidi primjer izgaranje benzina ispod: Neki stručnjaci kažu da ako je potrošnja nafte u svijetu i dalje na trenutni tempo, poznate i iskoristive zalihe će biti iscrpljeni do sredine stoljeća. I onda? Što će se dogoditi ako imamo više ulja? Već postoje šanse da zauzmu ulje! Veći podmornice titutos benzina su: alkoholi (metanol i etanol), prirodni plin (ja ratnik), a vodik, poznat kao "gorivo budućnosti" U tom smislu, brazilska vlada kako bi djelomično zamijeniti benzin s alkoholom - gorivo, dodatak utvrđenom iznosu od oko 25% alkohola (etanola) na benzinu. Danas imamo naše ceste kruže automobile proizvedene u 80, motori rade samo s alkoholom hidratiziranog, novije modele automobila na benzin (koji zapravo koriste mješavine benzin / alkohola), biogoriva (koji rade na oba goriva u bilo Omjer) i vozila s pogonom na prirodni plin CNG. Jeste li primijetili da se često benzinski automobili gube svoje prihode? Gorivo. Koji je najbolji?
