1 Coal and Petroleum

2 Coal and petroleum are sources of energy that are non- renewable. They were made in the nature a long time before and they will finish after long-time use

3 Coal is a combustible,sedimentary, organic rock, formed from vegetation. In other words coal is a fossil fuel created from the remains of plants that lived millions of years ago. it is considered as a non renewable source of energy because it takes too much time to form.

4 Peat Lignite Sub-bituminous coal Bituminous coal Anthracite Graphite

5 Coal mainly consists of carbon. It also consists some metal compound and some other impurities.

6 Coal as fuel Coking and use of coke Ethanol production Coal tar General Applications of Coal

7 Coal is used as a solid fuel to produce electricity. Coal is used as a solid fuel to produce heat through combustion

8 Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. It is further used in making steel The reaction of coal and natural gas was used for making Buna rubber. This reaction makes ethanol and it is used to make Buna rubber.

9 Coal tar is a brown or black liquid of high viscosity, which smells of naphthalene and aromatic hydrocarbons. Being flammable, coal tar is sometimes used for heating or to fire boilers. Tar is used in treatment of the skin disease psoriasis, where coal tar is the most effective. It is also used to make roads.

13 Legend -- coal deposits Map of the Earth showing coal deposits

14 Petroleum is a naturally occurring,flammable liquid, that are found in geologic formations beneath the earth's surface. It was produced when sea creatures died and got covered with sand and clay. Under high pressure, these dead organisms changed into petroleum and natural gases. How is petroleum formed?

15 Petroleum may be taken to oil refineries and the hydrocarbon chemicals separated by distillation and treated by other chemical processes, to be used for a variety of purposes like: Asphalt Diesel fuelLiquefied petroleum gas (LPG) Lubricating oils Uses of petroleum products

16  Petrochemicals  Fuel oils  Gasoline  Kerosene

17 Ethane and other short-chain alkenes Diesel fuel (petro diesel) Fuel oils Gasoline (Petrol) Jet fuel Kerosene Liquefied petroleum gas (LPG) Lubricants (light machine oils, motor oils, and greases). List of all organic fuels (fossil fuels)

18 Wax, used in the packaging of frozen foods, among others. Sulfur or Sulfuric acid. Bulk tar. Asphalt Petroleum coke, used in specialty carbon products or as solid fuel. Paraffin wax Aromatic petrochemicals to be used as precursors in other chemical production. Plastics

19 Composition ElementPercent range Carbon83 to 87% Hydrogen10 to 14% Nitrogen0.1 to 2% Oxygen0.1 to 1.5% Sulfur0.5 to 6% Metals< 0.1%

20 Whats an oil well? An oil well is a general term for any boring through the earth's surface that is designed to find and acquire petroleum oil hydr ocarbons. It is used to pump out petroleum.
