Which one would you prefer?
Steam reformer:
CH4 + H2O -> CO + 3H2
CO + H2O -> CO2 + H2
Dry reformer:
CH4 + CO2 -> 2CO + 2H2
1) The SR uses steam injection, the DR doesn't have steam, which can be good.
2) The DR doesn't yield much H2 for a given amount of CH4... And the water shift reaction of the SR would even yield more H2. Minus point for the DR.
