Abstract
A method of reforming a gasification gas, in order to decompose the impurities contained therein, and a use of a noble metal catalyst in the pre-reforming of gasification gas. The gas is brought into contact with a metal catalyst in the presence of an oxidizing agent. The reformation is carried out in several stages, wherein in at least one of the first stages a noble metal catalyst is used, and in a second stage which follows the first stage the catalyst used is a metal catalyst. The use of a noble metal catalyst can reduce the risk of deactivation of the metal catalysts and can increase the operating life of the catalyst.
