Coal BY KARMA g.

The types of coal can determine
by:

HARDNESS
% OF CARBON CONTAIN
COLOUR
a combustible black or dark brown rock consisting chiefly of carbonized plant matter, found mainly in underground seams and used as fuel.
COAL:
It was formed in Carboniferous Period
"285 m"
Chinese were the first user " 3,000 yrs "

WHY PEOPLE USE COAL MOST?
AFFORDABLE FUEL= $ 40 per barrel
EASY TO BURN
IMPACTS
Emission of Greenhouse gas
"Global warming "
1 tone of = 2.4tones of CO

Mining death= 1000 each yr



ABUNDANCE= Almost country has coal reserve
Destruction of Habitat\ Ecosystem

Danger to health
LOW COST TO BUILT STATION
It is Non-Renewable resource.
Dr.Thomas Walker discovered it, in
1750
(US)
IF IT IS USE PRESENT IN
CONSUMPTION RATE =
200
YEARS
Every year:
4%
CASE STUDY IN CHINA
Formation and how it is extracted.
Contents: Prediction of consumption of coal till 2030

Advantages and Disadvantages


Methods of extraction
Usage of COAL
Coal is transport i following ways:

Train\rail
Ship
Truck
ANOTHER WAY OF DIVIDING RESOURCES ON THE BASIS OF WHERE THEY ARE FOUND:


RESOURCE


UBIQUITOUS RESOURCE LOCALIZE RESOURCE
Sunlight
Air

COAL
OIL
NATURAL GAS
Top 10 countries: Producer and Consumer
6 Billion
tonnes =
Per year
flow trade of coal
What other elements consists
in Carbon?

1.Hydrogen
2.Oxygen
3.Sulfur
4.Nitrogen
5.Arsenic
6.Selenium
7.Mercury
8. Carbon
ANTHRACITE: 92-95%
BITUMINOUS: 60-80%
LIGNITE:25-35%
PEAT:
50%
Carbon %
Who will be the hero in future?
1.Coal liquefaction(CTL):Converting coal into liquid fuels
Methods:
Direct methods = Liquid
Indirect methods= with CO+H
2.Synthetic natural gas( SNG): Converting coal into natural gas.

China =4% is covered by SNG
