ABSTRACT:
A process for removing nitrous oxides from a gas, comprising the step of passing air through a bed of particulate material including a carbonaceous material to fluidize the material and promote combustion of the fuel and adding additional carbonaceous material to the bed. Additional air above the area of introduction of the air passes through the bed and passes the gas through the bed so that carbonaceous material scavenges the oxygen in the nitrous oxides.
