  1. Fossil Fuel

  2. What are fossil fuel • Fossil fuel are hydrocarbons, primarily coal, fuel oil or natural gas formed from the remains of dead plants and animals. • After food, fossil fuel is humanity's most important source of energy. There are three major fuels : • Coal • Oil • Natural Gas.

  3. Fossil fuel –crude oil • As found in the earth, oil may have a variety of properties. Some forms are black, others dark green, and some light like kerosene. The liquid ranges from very viscous to easy-flowing. Crude oil usually consists of a mixture of hydrocarbons having varying molecular weights and differing from one another in structure and properties.

  4. Fossil fuel –crude oil • These various species are separated into groups, or fractions, by a process of distillation called refining. Oil fuel, in all of its usable forms, is a refined product, unlike coal and natural gas which can often be burned in their natural condition.

  5. Fossil fuel –crude oil • Petroleum is a mixture of liquid hydrocarbons (chemical compounds containing only hydrogen and carbon) plus various impurities such as sulfur. Unprocessed petroleum is usually called crude oil, although it has been called mineral oil and Seneca oil, named for the Seneca Indians of Western Pennsylvania.

  6. Fossil fuel –crude oil • The name petroleum is from a combination of Latin words meaning "rock oil". We refer to it here simply as oil.

  7. Use of oil • Oil is used primarily in the form of gasoline and deisel to power vehicles.eg cars, trucks, buses, boats, trains and planes run on oil. • Oil are also used to power portable devices and stationery engines. • It is beyond the scope of this lesson to go into detail on the use of oil

  8. Disadvantage of oil • Oil spills • Oil removed by microbes, evaporation and photo oxidation process • Emissions

  9. Advantage of oil • It has high energy density. • Production systems are simple • Storage and transportation systems are simple • For transportation it feeds an established distribution bas • Safety hazards (and safe handling procedures) are well understood  • Systems for use as a fuel are simple • Spills and leaks are controllable using existing technology • As raw material in chemical synthesis it is extremely flexible
