In a pulse reactor, a
carrier gas, which may be
inert or possibly one of the reactants, flows over the
catalyst and small amounts of the other reactant or reactants are injected into the
carrier gas at intervals. A pulse reactor is useful for exploratory work but kinetic results
apply to a transient rather than to the steady state conditions of the
catalyst.
