Reformation of Hydrocarbon Fuels
Hydrogen is not readily available in nature in the unbound molecular form. Thus, hydrogen is not a primary energy source but, like electricity, is an energy carrier and must be converted from other sources of energy. While hydrogen as an energy carrier has low environmental impact at the point of use, there may be signicant impacts from the production and distribution of hydrogen. There are many hydrogen production methods ranging from well-developed industrial processes to emerging pathways in both biological and thermochemical pathways. The most commonly used process to generate hydrogen is reformation of fossil fuels. This chapter will discuss the basic principles and state of the art of steam and autothermal reformation (ATR) processes.
