Boudouard Equilibrium

Select image and "Original" to enlarge.

I recently had occasion to recalculate the Boudouard equilibrium

C + CO2 ==> 2 CO

at 10 and 100 atmospheres. I did a lot of thermodynamic calculations in the 1980s at NREL, but was afraid I might be too rusty. Not so.

Carbon monoxide is under appreciated and too often maligned. It is a way of making carbon into as clean a gas as H2, any you only lose 18% of the C energy.

This spreadsheet has a discussion, then the calculations, then a simple diagram in degrees kelvin, and finally all three pressures in degrees C.
