Abstract
A method of reforming a gasification gas, in order to decompose the impurities comprised in the gas, and a use of a precious metal catalyst in the pre-reforming of gasification gas. The gas can be brought into contact with a metal catalyst in the presence of an oxidizing agent. The reformation can be carried out in several stages, in which case at least in one of the first catalytic zones a noble metal catalyst can be used, and in a secondary reforming stage which follows the first, preliminary reforming zone, the catalyst that can be used is a metal catalyst. Oxygen can be fed separately into each of the catalyst zones. 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.
