Abstract
Hydrogen generators and processes for operating hydrogen generators using partial oxidation/steam reforming of fuel are provided that can achieve desirable Net Hydrogen Efficiencies over a range of fuels and hydrogen product production rates and purities. Superheated steam for the reformer feed is provided through indirect heat exchange with the reformate and through indirect heat exchange with a flue gas. The relative portions of superheated steam from each heat exchange is adjusted to enhance Net Hydrogen Efficiency as a demand condition such as hydrogen product production rate or purity changes, and cooler oxygen-containing gas is used to avoid precombustion temperatures in the reformer feed.
