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.

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.

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.

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.

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.

9
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

10
Disadvantage of oil

• Oil spills
• Oil removed by microbes, evaporation and photo
  oxidation process
• Emissions

11
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
