1. A method for regenerating carbonaceous adsorbent comprising the steps of:
a) providing a carbonaceous adsorbent comprising a catalyst and adsorbed contaminants,
b) pyrolysing of the adsorbed contaminants,
c) reactivating the carbonaceous adsorbent by subjecting the carbonaceous adsorbent to steam thereby obtaining a reactivated carbonaceous adsorbent,
d) cooling the thus obtained reactivated carbonaceous adsorbent to a temperature of less than 250° C. and
e) oxidizing catalyst that is in a reduced state following steps b) and c) comprised in the reactivated carbonaceous adsorbent.
