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

6
Gasifiers types
  • Fixed bed gasification updraft, downdraft, or
    cross-flow
  • Fluidised bed gasification circulating fluidised
    bed, bubbling bed and internally circulating
