Abatement of NO using adsorption, desorption and reduction (ADR) using Dielectric Barrier Discharge (DBD) is presented. The NO was adsorbed on a coconut shell granular activated carbon (GAC) impregnated with copper (2%). The ADR setup consisted in a sequence of DBD reactors. The first one also contained the GAC. The adsorption was carried out at about 32 degrees C with a gas mixture of 250 ppm of NO in air (10% of O-2) at the gas velocity of 0.1 m/s. The mechanisms of NO uptake include simple adsorption and catalytic reduction on the copper impregnated GAC. During the desorption/reduction process, a stream of N-2 at the gas velocity of 0.1 m/s was passed through the reactors in presence of non-thermal plasma. A set of voltages between 10 to 36 kV(pk-pk) and the frequency of 800-1400 Hz was tested to obtain the required plasma for an efficient NO desorption and reduction. The experimental results showed that the ADR system is able to reduce >96% of the NO with a single reactor and >99% of NO with two reactors in series. Besides, cyclic ADR tests indicated that the GAC preserve more than 90% of its uptake capacity after 30 cycles. |
