Gasification: -”Conversion of any carbonaceous fuel into a gaseous product with a usable heating value” [1]

C(s) + ½ O2 → CO(g) -111 kJ/mol

CO(g) + ½ O2 → CO2(g) -283 kJ/mol

C(s) + O2 → CO2(g) -394 kJ/mol

“Investing” 28% of the heating value of pure carbon by partial oxidation result in a gaseous product with 72% (283/394) of the heating value remaining.

In practice, carbonaceous fuels contains hydrogen, =>

CHx --> CO + H2; => 75-88 % efficiency in modern processes

PEBG Projects (2009-2015)

▪ Gasification of forest residues to

generate syngas that is suitable for

fuel synthesis

▪ Characterization of the process

performance as a function of λ

▪ Influence of fuel type, pressure, fuel

particle size etc.
