The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. The re-dispersion technique involves the formation and removal of carbonyls with the active metals. The carbonyl formation and removal effectively re-disperses the catalyst metal.

Regeneration of partial oxidation catalysts

A pretreatment method for increasing the average pore size of a catalyst support is disclosed which increases the diffusivity and effectiveness factor &#x3b7;. The pretreatment method includes calcining the support in moisturized air at an elevated temperature sufficient to increase the average pore size. In some embodiments, the support may be treated with an acidic/basic solution prior to the calcination step. Alternatively, the calcination step may occur in a gas mixture including water/air/acidic (or basic) gases.
