Abstract
A packed-bed silent discharge plasma (PBSDP) reactor was constructed by filling dielectric materials in a cylinder silent discharge plasma reactor with the gap of 18.5 mm. The dielectric materials assessed included Al2O3 and glass beads with various sizes. The simulated gas streams contained 1000 ppmv acetaldehyde, select O2 content and balanced N2. Experimental results show that packed materials in silent discharge reactors can enhance acetaldehyde removal, whereas Al2O3 is better than glass beads. For the gas streams containing 1000 ppmv acetaldehyde, 5% oxygen, and balanced nitrogen, 99% removal efficiency is achieved, whereas the energy yield is 13 g/kWh. The maximum energy yield of 29 g/kWh is achieved for the gas stream containing 3% O2. Product analysis indicates that more than 90% carbons from acetaldehyde are converted to CO2 and CO. Acetaldehyde removal efficiency increases with increasing applied voltage, however, high concentrations of NO2 and N2O are generated simultaneously.
