Review of Small Stationary Reformers for Hydrogen Production

A variety of reforming technologies that might be used in distributed hydrogen production at refueling stations are reviewed. These include steam methane reforming (SMR), partial oxidation (POX), autothermal reforming (ATR), methanol reforming, ammonia cracking and catalytic cracking of methane. Novel reformer technologies such as sorbent enhanced

Aspen Plus Ammonia Model - UMD

Reforming Unit This unit contains two sections, one is primary reforming, and another is secondary reforming. The desulfurized hydrocarbon feed is reformed to hydrogen and carbon oxides in the presence of steam in the primary reformer, and additionally with hot air in the secondary reformer. The reformed gas contains about 0.3 vol% CH4.
