Gasification process

• Gasification is the conversion of biomass to a
  gaseous fuel by heating in a gasification medium
  such as air, oxygen or steam.
• gasification includes both biochemical and
  thermochemical processes
• gasifying agent air, oxygen/steam and
  hydrogenation

Gasifiers types

• Fixed bed gasification updraft, downdraft, or
  cross-flow
• Fluidised bed gasification circulating fluidised
  bed, bubbling bed and internally circulating
