How much energy does it take to produce a gallon of gasoline?
The math behind the claim is simple. Refinery efficiency is about 90 percent and the energy content of a gallon of gasoline is about 132,000 Btu. Put that together and you have about 13,000 Btu of energy cost per gallon of gasoline produced, which is equivalent in energy terms to 4 kilowatt hours.
What is the energy density of natural gas?
82.7 MJ/m3
The standard unit is megajoules per cubic meter. The energy density of a natural gas lies in the range of 900-2200 Btu/ft3or 33.4–82.7 MJ/m3.
How much energy is in a liter of gasoline?
One litre of gasoline contains the energy equivalent to 8.9 kWh of electricity.
What is the energy in a can of gasoline?
For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon. As such, 1.38 gallons of propane has the same amount of energy as one gallon of conventional gasoline.
Does gasoline in a gas can have energy?
Gasoline also known as petrol is an energy-dense secondary fuel that can be thought of as an energy currency. It is used to power many heat engines, most importantly it acts as a fuel for a large proportion of cars….Composition.
| Energy Density (MJ/L) | 34.2 |

| Specific Energy (MJ/kg) | 44.4 |
What fuel has the highest energy density?
hydrogen
The highest energy density fuel is hydrogen, which is also the simplest chemical component in existence. Gasoline, which is derived from refining crude oil, contains much more energy than coal (twice the lower grade bituminous) or wood (three times).
What is the energy content of gasoline fuel?
116,090 Btus per gallon
For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon. As such, 1.38 gallons of propane has the same amount of energy as one gallon of conventional gasoline.
What is the energy density of a fuel?
Energy density is the energy per unit volume of a fuel. displaystyle E_ {d} = frac {E} {V} E d
What are the units of energy in gasoline?
It therefore has units of energy per length cubed or energy per mass. Gasoline has an energy density of about 45 megajoules per kilogram (MJ/kg). Gasoline is a mixture of the lighter liquid hydrocarbons used chiefly as a fuel for internal-combustion engines. It is produced by the incomplete refinement of petroleum;
What is the chemical composition of gasoline?
What we purchase at the pump is a mixture of hundreds of compounds. However, given the boiling points used to distill gasoline (120 – 400 degrees Fahrenheit), we know its hydrocarbons have between 6 and 12 carbon atoms. Most people consider octane – C8H18 – an acceptable average value 1. Octane has a density of 0.703 g / mL or 2,661.14 g / gal.
What is the specific gravity of a gallon of gasoline?
The specific gravity of gasoline is from 0.71 to 0.77, with higher densities having a greater volume of aromatics. Finished marketable gasoline is traded (in Europe) with a standard reference of 0.755 kg/L (6.30 lb/US gal), and its price is escalated or de-escalated according to its actual density.
