Gas from
prim.ref.
• Combustion:
H2 + 1/2O2 = H2O
Hrx = -242 kJ/mol
Burner
• Reforming and Water Gas Shift:
CH4 + H2O = CO + 3H2
Hrx = 206 kJ/mol
CO + H2O = CO2 + H2
Hrx = -42 kJ/mol
• Energy:
Heat is recovered in a Waste Heat Boiler (Steam)
• Catalysts:
Synthesis gas + H2O
MeOH 5
Methanol Synthesis
•Chemical Reactions:
CO + 2H2 = CH3OH
Hrx = ?? kJ/mol
CO2 + 3H2 = CH3OH + H2O
Hrx = ?? kJ/mol
• Heat of Formation Data:
CO
:
H0f = -111 kJ/mol
CO2
:
H0f = -393 kJ/mol
H2
:
H0f =
0 kJ/mol
CH3OH :
H0f = -201 kJ/mol
H2 O
H0f = -242 kJ/mol
:
Answer: -90 kJ/mol and -50 kJ/mol  Exothermic Reaction
