Gasoline is a petroleum-derived product comprising a mixture of liquid aliphatic and aromatic hydrocarbons, ranging between C4 and C12 carbon atoms with the boiling range of 30–225°C. It is predominantly a mixture of paraffins, naphthenes, aromatics and olefins.

Unleaded gasoline contains at least 15 hazardous chemicals including, by volume, benzene (∼5%), toluene (35%), naphthalene (∼1%), trimethylbenzene (∼7%), and MTBE (∼18%, in some states).

The typical composition of gasoline hydrocarbons (% volume) is as follows: 4-8% alkanes; 2-5% alkenes; 25-40% isoalkanes; 3-7% cycloalkanes; l-4% cycloalkenes; and 20-50% total aromatics (0.5-2.5% benzene) (IARC 1989).

Simply, “Gasoline contains mainly alkanes (paraffins), alkenes (olefins), and aromatics,” according to Advanced Motor Fuels. The most prevalent hydrocarbons in gasoline, alkanes are saturated hydrocarbons with large reserves of energy.

Alternative Titles: gas, gasolene, motor gasoline, petrol. Gasoline, also spelled gasolene, also called gas or petrol, mixture of volatile, flammable liquid hydrocarbons derived from petroleum and used as fuel for internal-combustion engines. It is also used as a solvent for oils and fats.

There are 6,923 trillion cubic feet (Tcf) of proven gas reserves in the world as of 2017. The world has proven reserves equivalent to 52.3 times its annual consumption. This means it has about 52 years of gas left (at current consumption levels and excluding unproven reserves).

By the year 2080, the world’s supply of oil will be in steep decline. It will take more energy to take the petroleum out of the ground than can be gained from the use of the produced oil. This would mean gasoline prices would skyrocket as countries would get low in their reserves of oil.

The truth is, any of the fossil fuels that are usually in the discussion, like oil and natural gas, probably won’t be running out for generations, if ever. Some resources are able to be recycled, and others can be recovered. So as our reserves dwindle down, they’ll just start becoming more expensive to produce.

It is not feasible to immediately stop extracting and using fossil fuels. The global economy, human health and livelihoods currently depend heavily on oil, coal and gas. But over time, we need to displace fossil fuels with low-carbon renewable energy sources.

Fossil fuels take a toll on the environment. They cause obvious problems such as oil spills and smog filled air. They also cause other, more complicated problems that are not so easy to see. Acid rain, for example, caused partially by sulfur in fossil fuels, damages buildings and harms trees, aquatic life, and insects.

fossil fuel coal, oil, or natural gas. Fossil fuels formed from the remains of ancient plants and animals.

Fuel meaning: Meaning of fuel is a substance that is burned to provide nuclear energy, heat or power. Materials like coal, wood, oil, or gas can provide heat when burned. Methanol, Gasoline, Diesel, Propane, Natural gas, Hydrogen are types of fuel. Nuclear energy is produced by burning plutonium.

Primary energy sources take many forms, including nuclear energy, fossil energy — like oil, coal and natural gas — and renewable sources like wind, solar, geothermal and hydropower.

Fuels can be generally classified into two factors:

• Solid Fuels.
• Liquid Fuels.
• Gaseous Fuels.

Wood, coal, LPG, kerosene, diesel etc. Characteristics of ideal fuel: It should have high calorific value. It should burn without giving out any smoke or harmful gases.
