[Bioconversion] How do you make Methanol along with Charcoal?

[Thomas Reed]

Dear Silva:

I think you are confusing the making of methanol by pyrolysis, in which 
case you get a 2% yield amongst all the other products from hardwood and 
0% from softwoods - with making methanol from synthesis gas - CO + H2, 
in which case you get a >50% yield.
