Following the preparation of a catalyst
or following its insertion
into a catalytic reactor, it is often subjected to various treatments before the
start of a catalytic run. The term pretreatment may, in general, be applied to this
set of treatments. In some cases the word activation
is used. It implies that the material is converted into a catalyst
or into a very much more effective one by the pretreatment.
