Figure 4. Methane Slip catalyst cleanup beds show any appreciable change in temperature. Due to the fact that the shift beds remain at constant temperature, one would expect the carbon monoxide levels exiting the reformer to remain constant throughout the transient Figure 7 shows that for a 2 second step increase in thermal input from 31 to 62 kWth, CO concentration remains largely unaffected.
