Examples Of Natural And Artificial Fuels In Daily Life

Fuels are materials that can undergo rapid oxidation, in which heat is released .

In the oxidation reactions of a fuel, the energy of the chemical bonds of its constituent compounds is transformed into other forms of energy, such as thermal or mechanical energy . Heat, carbon dioxide (CO 2 ) and other chemicals are also released .

Fuels have certain characteristics that influence their combustion process:

  • Calorific value . It is the amount of energy per unit of mass or volume that can be released during a fuel oxidation reaction.
  • Ignition point . They are the conditions of pressure and temperature necessary for a combustible substance to begin to burn when a heat source is approached, and to continue burning if the heat source is removed.

Fuels fulfill a wide variety of functions within the daily life of every individual. They are used to generate electricity, heat environments, heat water or other substances, propel engines, among many other functions.

Types of fuels

One of the main classifications of fuels refers to how they were originated. In this sense, they can be classified into natural and artificial fuels.

Natural fuels

Natural fuels are those that are found in nature and that humans use to obtain energy from their combustion . Natural fuels can exist in three states of aggregation:

  • Solid fuels . Coal, wood and natural peat.
  • Liquid fuels . The oil.
  • Gaseous fuels . Natural gas.

Many of the natural fuels are fossil fuels . Fossil fuels originated millions of years ago from the remains of dead plants and animals that accumulated inside the earth’s surface, and were subjected to decomposition reactions and high pressures and temperatures. The best known fossil fuel is oil.

Examples of natural fuels

  1. Firewood
  2. Coal
  3. Agricultural residuals
  4. Petroleum
  5. Peat
  6. Anthracite
  7. Natural gas
  8. Wood

Artificial fuels

Artificial (or synthetic ) fuels are those that humans obtain when they apply thermochemical processes to a natural fuel. The objective of obtaining artificial fuels is to generate a greater amount of usable energy for some purpose.

Among artificial fuels are biofuels or biofuels, which are obtained from biomass . Some of the most used biofuels are biodiesel and biogas.

Examples of artificial fuels

  1. Butane
  2. Dimethyl ether
  3. Biogas
  4. Diesel oil
  5. Liquefied petroleum gases
  6. Gasoline
  7. Methanol
  8. Kerosene
  9. Ethanol
  10. Biodiesel
  11. aviation fuel
  12. fuel oil
