Coal BY KARMA g.
The types of coal can determine
% OF CARBON CONTAIN
a combustible black or dark brown rock consisting chiefly of carbonized plant matter, found mainly in underground seams and used as fuel.
It was formed in Carboniferous Period
Chinese were the first user " 3,000 yrs "
WHY PEOPLE USE COAL MOST?
AFFORDABLE FUEL= $ 40 per barrel
EASY TO BURN
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
IF IT IS USE PRESENT IN
CONSUMPTION RATE =

Advantages and Disadvantages
Methods of extraction
Usage of COAL
Coal is transport i following ways:
ANOTHER WAY OF DIVIDING RESOURCES ON THE BASIS OF WHERE THEY ARE FOUND:
UBIQUITOUS RESOURCE LOCALIZE RESOURCE
Top 10 countries: Producer and Consumer
flow trade of coal
What other elements consists
Who will be the hero in future?
1.Coal liquefaction(CTL):Converting coal into liquid fuels
Direct methods = Liquid
Indirect methods= with CO+H
2.Synthetic natural gas( SNG): Converting coal into natural gas.
China =4% is covered by SNG
