vi industrial process or a class of catalysts forms the basis of other
books, with information on: fundamental science of the topic, the use of
the pro- cess or catalysts, and engineering aspects. Single topics in
catalysis are also treated in the series, with books giving the theory
of the underlying science, and relating it to catalytic practice. We
believe that this approach is giving a collection of volumes that is of
value to both academic and industrial workers. The series editors
welcome comments on the series and suggestions of topics for future
volumes. Martyn Twigg Michael Spencer Billingham and Cardiff Contents
