Principle of Gasification Power Plant BIOMASS

Border Equilibrium

Methane production reaction C + 2H 2 = CH 4 + 75 [MJ/kmol] Oxidation C + O 2 = CO 2 + 406 [ MJ/kmol] H 2 + １/2 O 2 = H 2 O +242[ MJ/kmol] Reduction Boudouard reaction CO 2 + C = 2CO - 172.6 [MJ/kmol] Water-gas reaction C + H2 O = CO + H 2 - 131.4 [MJ/kmol] Water shift reaction CO 2 + H 2 = CO + H 2 O + 41.2 [MJ/kmol] Hiroshima Japan 30KW
