NICE leads the 8th project
Project leader: Prof. Kechang Xie
The whole chain of coal utilization industry is covered
Presenter
Presentation Notes
Last year, the Chinese Academy of Engineering launched a significant consulting project, this project was led the vice-president of CAE, Prof Kechang Xie. It was expected to clearly understand the situation, problems of the coal related industries by the project, and a reasonable measurement was expected to be put forward based on investigation of this project, and to be the policy-making reference for the government. Ten subprojects were set in this project, they are coal mining, coal distribution, coal-fired for power generation, coal combustion for industry, coal chemical conversion, poly-generation, electric power transmission, and also the water and coal resources survey, energy saving technology, pollution control technology were included. Obviously it almost covers the whole industry chain of coal from extraction to utilization, so it is a very comprehensive study. We, the National Institute of Clean-and-Low-Carbon Energy, led the 8th project, which is about coal to chemicals. I was the core coordinator of the subproject.

Presentation Notes
We selected about 20 products that cover almost all the coal-based chemicals. And about 18 subreports were worked out, and one summarized report was extracted from them. Here what I will show is the partial results of the summarized report.

China’s output in 2010
Presenter
Presentation Notes
China has the largest coal-based chemicals in the worlds. The right figure shows that china’s coke output is about 66% of the global output, 98% for Calcium carbide, 28% for methanol, and 32% for Ammonia. Most of the products are made of coal in China, that is China’s coal-bases chemicals capacity and output are top in the world. In China, coke has the largest production capacity, then Ammonia, Char, Calcium carbide, methanol, the rest is only about 3%.

Presentation Notes
Although China has the huge capacity and the largest output, unfortunately , the operation situation is not good, many operation rates are lower than 65%, that of DME is even lower than 40%. If we take the coke, ammonia, methanol, and calcium carbide industry as the traditional coal conversion industry, we can see it has a considerable fraction of outdated capacity, which means that the traditional coal chemical conversion industry is in depression, while the new just starts.

Coal Consumption In Coal Conversion Industry
Page 5
~ 673 million ton coal was consumed in 2010 to produce chemicals , about 21% of total coal production of China ~ 83% is converted via cokers. In gasification path, most of coal is used to produce methanol & ammonia
Presenter
Presentation Notes
Now, let’s look at the coal consumption, water consumption and carbon emission from the view of mass flow direction. In 2010 year, about 670 million ton coal was consumed to produce chemicals, is about 21% of the total coal production of China, about 83% is converted via pyrolysis path, in gasification path, most of coal is used to produce methanol and ammonia.

Water Consumption In Coal Conversion Industry
Page 6
~1.5 billion m3 fresh water is consumed in 2010 About 1.0% of the total fresh water consumed by industry Coke production used 67% fresh water
Presenter
Presentation Notes
For fresh water, about 1.5 billion m3 fresh water is consumed in 2010, it is about 1.0% of the total fresh water consumed by all the industry of china, coke production used about 67% of fresh water.

CO2 emission In Coal Conversion Industry
Page 7
About 277 million ton CO2 was emitted in 2010, 3.6% of the total carbon emission of China 70% is from gasification path
Presenter
Presentation Notes
About 280 million ton CO2 was emitted by coal conversion industry in 2010, this is about 3.6% of the total number of China, and 70% is from gasification path.

Presentation Notes
The survey results indicates that there are larger development potential in all the coal production bases, the potential of Shanbei Base is the largest. The Shanbei Base, Shendong base and Ningdong Base reserve huge amount high quality coal, and oil and natural gas, they are call the “energy golden triangle” of china, the development in these regions is very hot.

Trend of Coal Conversion Industry
Presenter
Presentation Notes
From this slide, we can see that the coal consumption by coal conversion industry in the future will increase evidently, it would be 1600 million ton if all the approved and proposed projects were put into practice. Another point is the coal consumption portion for coke, ammonia and calcium carbide will reduce, that of new coal conversion products will increase. The obvious conclusion is that the new coal conversion industry is the trend of the coal to chemicals industry of China.

Future challenges: More resources would be consumed, More impacts on environment would be caused

Challenges of Coal Conversion Industry
Presenter
Presentation Notes
Based on above assumption, the coal consumption could be 2.5 time of current scale, water consumption could be 3 time, and CO2 emission could be 4 times. More resources would be consumed and more impacts on environment would be caused if the potential came into reality.

Presentation Notes
At last, we did the SWOT analysis and gave out some comments or suggestions to the coal to chemicals industry of China. We suggest to pay attention and study the impact of the development of shale gas on the coal conversion industry globally, the impact of the lower cost chemicals from Middle-east and NG condensate in North America, the impact of carbon taxi and so on. We also suggest to make the national roadmap, to establish the super-large national industrial demo park, to develop novel advanced technology, and to build up national clean production standards, assessment systems.
