Study Notes
Fossil Fuels
- Fossil fuels are the primary energy sources for most energy conversion devices, such as steam turbines, gas turbines, petrol engines, and diesel engines.
- Fossil fuels are important for daily energy needs, contributing to approximately 80% of global energy consumption.
Types of Fossil Fuels
- Conventional Fossil Fuels: Coal, natural gas, and petroleum.
- Solid Fuels: Coal, biomass, petroleum coke
- Liquid Fuels: Gasoline, diesel, jet fuel, fuel oils
- Natural Gas: Methane, ethane, propane, butane
- Coal is the most abundant fossil fuel, historically important for the Second Industrial Revolution, and currently used for electric power generation, steelmaking, and cement production.
- Oil and gas originate from ancient marine organic matter.
- Petroleum is a complex mixture of hydrocarbons.
Global Carbon Cycle
- Photosynthesis is the process where plants convert solar energy, carbon dioxide, and water into sugars and oxygen.
- Decay process decomposes organic matter, releasing carbon dioxide back into the atmosphere.
Coal Formation
- Coal is formed from ancient plant material subjected to high pressure, geological forces, and temperatures over millions of years.
- Temperature with depth in the Earth increases, transforming peat into coal.
Coal Analysis
- Proximate Analysis determines moisture, volatile matter, ash content, and fixed carbon.
- Ultimate Analysis determines carbon, hydrogen, nitrogen, sulfur, and oxygen content.
Basis of Analysis
- As Received Basis: The analysis reflects the composition of the coal as it is received.
- Dry Basis: Moisture is removed before analysis.
- Dry, Ash-Free Basis: Moisture and ash are removed before analysis.
- Conversion of Basis allows for comparison of coal samples with different moisture and ash content.
