[Gasification] How much ton of biomass will burn to produce 1 ton of CO2?

Being speculative based on some known facts, I would assume that since 1
ton of biomass (based on Ideal Gasifiction (NOT "syngas", but rather
"woodgas" or "producer gas", an average of small gasifiers is a common CO2
output of approximately 11 to 30 % by volume (See sample GCMS report below)

It would be a qualified guess to say, 7 to 8 tons of biomass, BASED on
reasonable gasification of the said biomass. I am
NOT considering incineration, ONLY "home made" gasification.
