A gas stream containing e.g. molecular hydrogen is used for the regeneration of a catalyst for NOx and SO2 removal from the flue gas of a gas turbine. In order to reduce the consumption of regeneration gas, the gas inlet is located between the SCOSOx catalyst (2) and the SCONOx catalyst (3). The reg
A gas stream containing e.g. molecular hydrogen is used for the regeneration of a catalyst for NOx and SO2 removal from the flue gas of a gas turbine. In order to reduce the consumption of regeneration gas, the gas inlet is located between the SCOSOx catalyst (2) and the SCONOx catalyst (3). The regeneration gas leaves the catalyst chamber upstream of the SCOSOx catalyst and is recycled. For the regeneration of the SCONOx catalyst and to keep SO2 containing gas from entering the SCONOx catalyst, a second regeneration gas inlet is located downstream of the SCONOx catalyst. The regeneration gas entering the catalyst chamber through this port passes the SCONOx (3) and the SCOSOx catalyst (2). The direction of the flow in the SCONOx catalyst can also be reversed. In another example, regeneration gas outlets are located both upstream of the SCOSOx and downstream of the SCONOx catalyst. But, only the regeneration gas from the SCONOx catalyst is recycled.
