Advanced Gasification Process Overview
Process feedstock is clean woody biomass chips
Product Gas

• Process Flow
• Organic feedstock at 3- is fed thru a hopper and
  through an air lock
• In the air lock nitrogen purges out the oxygen
• Blended with steam the feedstock is mixed with
  14000f heat
• As the heat mixes an instantaneous reaction
  gasifies the feedstock breaking it down into
  its basic elemental gases
• Cyclones separate the product gas and any Char
• The char is burned in the combustor to generate
  heat sent to the gasifier
