The Application of Hydrocarbon Fuels

 "What is Hydrocarbon Fuel".

Hydrocarbon fuel is derived from a hydrocarbon, which includes gasoline and jet fuel, both of which have significant uses in the modern world, from powering cars to planes to lawnmowers. It is an organic compound consisting of hydrogen and carbon found in crude oil, natural gas, and coal. Hydrocarbons are highly combustible and the primary energy source of the world. Its uses consist of gasoline, jet fuel, propane, kerosene, and diesel, to name just a few. 

Hydrocarbon has 2 types,  aliphatic and aromatic. Aliphatics are organic molecules that do not contain any carbon-carbon double or triple bonds. They can be linear, branched, or cyclic compounds. Aromatics are cyclic molecules that contain alternating single and double bonds. The three types of aliphatic hydrocarbons are alkanes, alkenes, and alkynes. Aromatic hydrocarbons include benzene. 


"The Application of Hydrocarbon Fuels"


Because HGLs straddle the gas/liquid boundary, their versatility and high energy density in liquid form make them useful for many purposes:

  • Fuels for cooking, heating, and drying
    Wood, crop wastes, coal, dung, and charcoal are the most widely used cooking fuels. Other people are turning to other cooking fuels such as sunlight, processed plant wastes (rice husks and other crop wastes made into pellets or briquettes), and biogas (a gas produced by rotting plant matter and human and animal waste).

  • Fuels for feedstock in petrochemical plants
    Fossil fuels (coal, crude oil or petroleum, natural gas liquids, and natural gas) are the primary sources of basic petrochemicals, but only about 9–10% of global fossil fuel production is ultimately used as a petrochemical feedstock; their primary usage remains the production of energy. This feedstock in petrochemical plants is used to make plastic, chemical, and rubbers.

  • Fuels for Transportation 
    The use of gasoline for transportation is the most commonly used fuel. However, there are multiple alternative fuels that are making their way to the market. These alternative fuels include such things as propane, natural gas, electric hybrids, hydrogen fuel cells, and biodiesel.

  • Fuels for additives 
    Additives to gasoline play an essential role in the treatment of fuels aimed at improving their properties in order to meet required specifications and to give them additional competitive benefits. The use of additives enables substantial reduction of engine exhaust emissions in many cases such as additives for influencing combustion, protecting fuel systems, improving lubrication, improving oxidation stability, and used in gasoline distribution

  • Fuels for a diluent
   One class of light hydrocarbons, referred to as “diluents,” are similar in nature to white gas or camping fuel used in a lantern or portable stove. Simply defined, the diluent is a light hydrocarbon mixture used to blend with heavy crude petroleum to reduce its viscosity to make it more fluid (“thinner”) and efficient to transport by pipeline. The diluent can come from refineries or natural gas production wells.


Hydrocarbon gas liquids have many uses

Hydrocarbon gas liquids (HGLs) are versatile products used in every end-use sector—residential, commercial, industrial (manufacturing and agriculture), transportation, and electric power.
