Liquid & Gaseous Fuels

The chapter deals with liquids and gaseous fuels, their composition, properties, uses and their effect on the environment. Liquid fuels e.g. petrol, diesel, and kerosene are mostly hydrocarbons which are the result of crude oil refining. Domestic, transportation, and industrial energy requirements are met with gaseous fuels such as the LPG (liquefied petroleum gas) and CNG (compressed natural gas). The chapter describes the properties of fuels including calorific value, octane number to petrol, cetane number to diesel, flash point, and volatility, which determine performance, efficiency as well as safety. Apple and practical uses are also described, such as internal combustion engines, power generation, and heating systems. Environmental factors, which include the emission of CO₂, NO, SO₂, and PM, are examined including the methods of cutting down on pollution in terms of fuel blending, catalytic converters and the use of alternative fuels. The chapter is a combination of chemical concepts and energy efficiency, optimization of combustion and industry, which gives the general view of fuel behavior in a comprehensive manner. Students acquire skills needed in designing energy, automotive technology, environmental management and industrial fuel applications that connect chemicals characteristics and actually real world applications in energy solutions.
