My question is why does one want to get rid of CO in the fuel gas as it has a higher heating value than that of hydrogen and without CO, an engine derating is much more significant just using hydrogen. The one component that significantly increases engine performance is methane in the produced gas as small quantities make a significant improvement in engine rating on produced gas.?

If the gasifier is brought up to temp with air and then switched to steam blown then the reaction will be endothermic on pure steam and will need to be toggled back to air blown hence town gas.

This well known stoichiometry of the water the water-gas shift reaction is : co+h20 <=>h2+co2+heat ( exothermic) In an efficient heat integrated scheme , the heat of the reaction can be recovered as superheated high pressure steam.
