Leland Methane AND cO2 can be made from syngas rich in co and h2 via ANEAROBIC METHANE BACTERIAS
BIOTHERMAL , IGT ,USA patented can do well . Methane compared to bioconversion of ethanol can de more viable from syngas On Tue, Dec 28, 2010 at 11:43 PM, Leland T Taylor <[email protected]> wrote: > CO2 may interfere with the catalysis.
