The remaining portion consists of other hydrocarbons like ethane (C2H6), propane (C3H8), and butane (C4H10), as well as small amounts of impurities like nitrogen, carbon dioxide, and water vapor. Natural gas is highly flammable and burns cleanly, producing fewer pollutants compared to other fossil fuels.

2. Propane: Propane (C3H8) is a three-carbon hydrocarbon and is often a byproduct of natural gas processing and crude oil refining. It is stored as a liquefied petroleum gas (LPG) under pressure but vaporizes into a gaseous state when released. Propane has a higher energy density than natural gas, making it an efficient and portable fuel.

3. Butane: Like propane, butane (C4H10) is another LPG, but it contains four carbon atoms. It is commonly used in portable camping stoves and lighters. Butane is highly flammable and provides a significant amount of energy per unit volume when vaporized.

4. Hydrogen: Hydrogen gas (H2) consists of two hydrogen atoms and is the lightest and most abundant element in the universe. It burns cleanly in air, producing only water vapor as a byproduct, making it an environmentally friendly fuel when generated using renewable energy sources.

5. Methane: Apart from being the primary component of natural gas, methane is produced as a renewable fuel through the anaerobic digestion of organic materials. Biogas, as it is called, has a composition similar to natural gas, with a high percentage of methane.

6. Ethane: Ethane (C2H6) is a two-carbon hydrocarbon found in natural gas and is used mainly as a feedstock for the petrochemical industry to produce ethylene, which is used in the production of plastics and other products.

Properties of gaseous fuels include high energy density, easy transportability, and clean combustion when compared to solid or liquid fuels. They are versatile and used for heating, cooking, electricity generation, and as feedstock for various industrial processes. Gaseous fuels play a significant role in meeting our energy needs and exploring cleaner energy alternatives in the quest for sustainable solutions.
