| 1. Apparatus for regeneration of a catalyst plant comprising:
a catalyst for the removal of SO2, and arranged downstream thereof, a catalyst for the removal of NOx, from the flue gas of
a gas turbine, and also at least one supply pipe for the introduction of regenerating gas, and at least one drain pipe for
the extraction of regenerating gas, wherein the supply pipe opens between the catalyst for the removal of SO2 and the catalyst
for the removal of NOx, and is connected to the drain pipe which leaves upstream of the catalyst for the removal of SO2, and
a further supply pipe for the supply of fresh regenerating gas is present and opens downstream of the catalyst for the removal
of NOx.
