Coal gasification reactions
equilibrium conditions
reaction effect of increase in temperature effect of increase in pressure kinetics (rate of reaction) heat of reaction
Solid-gas
carbon + oxygen = carbon monoxide (partial combustion) to right to left fast exothermic
carbon + oxygen = carbon dioxide (combustion) — — very fast exothermic
carbon + carbon dioxide = carbon monoxide (Boudward) to right to left slow endothermic
carbon + water = carbon monoxide + hydrogen (water-gas) to right to left moderate endothermic
carbon + hydrogen = methane (hydrogasification) to left to right slow exothermic
Gas-gas
carbon monoxide + water = carbon dioxide + hydrogen (shift) to left — moderate exothermic
carbon monoxide + hydrogen = methane + water to left to right slow exothermic
