Gasification
Energy conversion process• a process that converts organic or fossil based
carbonaceous materials
High temperature• achieved by reacting the material at high
temperatures • with a controlled amount of oxygen and/or steam
Syngas• hydrogen, carbon monoxide and methane
Hydrogen Membrane Separator
Fischer-Tropsch Reactor
Gas turbine or IC engine
Generator
Syngas(H2, CO, CH4)
Biodiesel
H2
Electricity
pure Hydrogen
Mechanical work
Why Steam?
No N2 dilution
Steam works as source of H2H element is limited in feedstockExpected Higher H2 concentration
Increase syngas heating value
Can be separated and recirculatedCondensed water can be reused
