Reactions and Thermodynamics of Catalytic Reforming

about 800 commercial catalytic reforming plants are in operation worldwide with a total capacity of about 0.4 billion tonnes (Farrauto and Bartholomew, 1997). The worldwide annual gasoline (petrol) consumption is about 1 billion tonnes, and reformate is a major constitutent of gasoline with about 40%. 

In the technical reforming process, hydrogen is recycled and added to the feed, although this is thermodynamically not favored, but is needed to suppress and limit coke formation. Typically, a H2 pressure of around 15 bar is used, which limits the
