Traditional coalNO2 &SO2 is harmful for plants and animals
Too much CO2 causes greenhouse effect
But coal combustion cannot be avoided
We need to change! We need clean coal!

clean coalDesulfurization
the removal of sulfur or sulfur compounds (as from coal or flue gas)
Compared with traditional coal
1) Largely eliminate the pollution of SO2 after burning coal
2) The sulfur that people get through the process of desulfurization can be

clean coal
A kind of clean coal
The use of carbon(two ways)
1) Store CO2 underground2) Combine CO2 with H2 to form methanol
Compared with traditional coal
1) Effectively control the emission of CO2 2) In order not to force global warming more strictly

Conclusion Clean coal can really reduce the pollution which are both detrimental to living things and environment.
But it is not easy to accomplish the change from traditional coal to clean coal
Problems …for example: the high cost

The clean coal can be popularized to modern
society?
• Criticism• Environmentalists believes
that the term clean coal is misleading.

Critics : Clean coal- continuing construction of coal-
powered plants
- encourages unsustainable mining practices for coal.
- there can be a large amount of energy required and pollution emitted in transporting the coal to the power plants.

Clean coal
• They view emissions and wastes as not being avoided but instead transferred from one waste stream to another.

The advantages of coal
1)Coal conversion------coal vaporization technology : the vaporization of coal can transform the coal to clean gaseous products ,on the one hand,we can use it to make clean civil gas fuel ,------coal liquefaction technology : the liquefaction of coal is a kind of technology that can transform solid coal to liquid fuel and industrial chemicals.

2)Coal processingUsing physical methods to process the raw coal before they put into use.This is the premise of rational coal and the most economical way to reduce pollution from coal burning3)Clean combustion and power generation technology4)Pollution control and resource recycling rechnology

Why are we going to liquefy the coal instead of just utilizing it?
Coal has the most abundant reserves and the most widespread distribution all over the world.
China: 1st output of coal & 3rd reserves of coal
What is the coal liquefaction?
German in 1913WWⅡ1970s oil crisis
