[Gasification] DIY GtL

[Li CHEN]

There are 600 gas fuel stations (via air gasification!) in China up to 2008.

Each station provides fuel gas for a village of 100 to 500 households.
*
*This gas composition is (generally):

Gas composition
	
Vol%
H2
	
9-12
CO
	
18-23
CH4
	
1-2
CO2
	
11 -- 14
N2
	
rest


Tar concentration should reach < 20 mg/Nm3 by water washing.

Waste water is then treated by both physical (decantation) and 
biological (using bacteria to decrease COD) processes.

After the treatment of this waste water, the water is re-used in the 
process, and "final tar" is landfilled.

I have some recent government reports or Chinese papers about the 
situation of gas fuel stations, but in Chinese.

I am preparing a presentation about the gasification status in china for 
a conference in Germany, but the powerpoint is not ready.

I can upload a powerpoint and send to the list a link for download after 
the conference.

Hope this information is useful for you.

Best regards,

Li
