For rather a long time numerical results in chemical kinetics could
only be obtained for very simple chemical reactions, most of which
were of minor practi ca 1 importance. The avail abil ity of fast
computers has provi ded new opportunities for developments in
chemical kinetics. Chemical systems of practical interest are
usually very complicated. They consi st of a great number of
different el ementary chemi cal reacti ons, mostly with rate
constants differi ng by many orders of magni tude, frequently with
surface reacti on steps and often wi th transport processes. The
deri vati on of a 'true' chemical mechani sm can be extremely
cumbersome. Mostly this work is done by setting up 'reaction
models' which are im- proved step by step in comparison with
precise experimental data. At this early stage mathematics is
involved, which may al ready be rather complicated. Mathematical
methods such as pertubation theory, graph theory, sensitivity
analysis or numerical integration are necessary for the derivation
and application of optimal chemical reaction models. Most
theoretical work aimed at improving the mathematical methods was
done on chemical reactions which mostly were of little practical
im- portance. Chemi cal engi neers, who evi dently k now well how
important the chemical model s and their dynamics are for reactor
desi gn, have al so to be convinced not only on the theoretical
work but also on its practical applic- abil ity.
