[Terrapreta] [Gasification] Catalysts for making Butanol

[Greg and April]

Yes, there has been improvement in the Weizmann process, essentially it's 
first exposing the "food" to a related bacterium, which is more selective in 
it's waste products, and then once that organism is done, it's waste 
products are exposed to the Weizmann organism, which gives a better than 90% 
return in butanol.

What I am trying to do, is find out what catalysts the industry is using to 
produce butanol.
