Depending upon the nature of the active component, two different types of supported catalyst may be distinguished. When the active component is very expensive (as with precious metals), the objective is a maximum active surface area per unit weight of the active component. With less costly active components, such as base metals or base metal oxides or sulfides, a maximum active surface area per unit volume is most attractive. The reason for this is that a high active surface area causes a relatively small catalytic reactor volume to be sufficient to achieve a technically satisfactory conversion. When the costs of the reactor dominate, a high loading of the support maximizing the active surface area per unit volume will therefore be most favorable. When, on the other hand, the costs of the active component are most important, the maximum active surface area per unit weight of active component is desired. Expensive active components, therefore, will be applied to supports at low loadings, leading to small or very small supported active particles and thus providing a high active surface area per unit weight of active component.
