The deactivation of catalysts used in the catalytic reforming of liquid fuels takes place by several mechanisms: carbon deposition, sulfur poisoning and, in some cases, sintering. In any particular case, all of these may be present, and their interaction is not always predictable.

There are a number of approaches to minimizing deactivation, including limiting the metal cluster size, increasing steam content, and use of oxygen-conducting supports.

The mechanisms of deactivation specifically for the reforming reactions will be examined, as well as the approaches that have been reported to limit deactivation.
