[Gasification] Fwd: Gasification Digest, Vol 80, Issue 8

[Ronal W. Larson]

List,  Boris, Frits

	1.   It seems Boris might be mostly interested in biochar  (we don’t usually hear the word “pyrolysis” on this gasification list.)  One resource I have recently learned about that does a good job on many types of pyrolysis (char-making):
	https://fortress.wa.gov/ecy/publications/documents/1107017.pdf <https://fortress.wa.gov/ecy/publications/documents/1107017.pdf> 
A little old, but might contain some useful ideas for continuous char-making.
	Boris may want to participate on the (sister) biochar list, which sometimes uses the word “gasification”, but is mostly about pyrolysis (char-making).  
	Found at https://groups.yahoo.com/neo/groups/biochar/info <https://groups.yahoo.com/neo/groups/biochar/info>;  We hear about continuous char-making every few months.  

	2,  Frits:  Any char-making (pyrolysis) in your own work with engines?
	
	3.  I know of two places doing continuous pyrolysis (char-making, not char-consuming) and engines:
		http://bekbiochar.pbworks.com/w/page/6465132/FrontPage <http://bekbiochar.pbworks.com/w/page/6465132/FrontPage>   and   http://www.allpowerlabs.com/products/biochar <http://www.allpowerlabs.com/products/biochar>   (in Berkeley)
		and
		http://www.vgridenergy.com/ <http://www.vgridenergy.com/>

	4.  There are probably many more running engines AND char-making, such as ??
