average 2.45 billion metric tons per
year. One ton of feedstock can be
converted to 721 liters (186 gal-
lons) of methanol. As a renewable
resource, biomass represents a
potentially inexhaustible feedstock
supply for methanol production.
The Production Process
Methanol can be produced from
biomass through a thermochemical
process known as gasification. The
biomass is subjected to elevated
temperatures and pressures (in
some processes) to form a synthe-
sis gas (syngas). The syngas (a mix-
ture of carbon monoxide and
