Although in recent years, extensive research has been conducted toward this process, supercritical gasification of biomass is still in a stage of R D.

When methanol is made from natural gas, the gas reacts with steam to produce synthesis gas, a mixture of hydrogen and carbon monoxide. This then reacts with a catalytic substance at high temperatures and pressures to produce methanol. The process is similar when methanol is produced by the gasification of biomass. The production of methanol from biomass or coal can cost almost twice as much as production from natural gas.

Various gasification schemes have been conceived for the direct production of H2 (and C02) instead of synthesis gas. Matsumura has reviewed the gasification of biomass with near- and super-critical water [42], The presence of liquid water suppressed the formation of char but not of tars. Full gasification proceeds in the presence of metal catalysts at 350-600 °C but also in absence of any catalysts at 500-750 °C. This subject is discussed elsewhere in this book [26],...
