The effect of residential time on the CO2 reduction from combustion flue gases by a ferroelectric packed bed reactor

An investigation has been conducted to reduce CO/sub 2/ from combustion gases using an AC ferroelectric packed bed reactor. This ferroelectric packed bed reactor consists of two mesh electrodes packed with ferroelectric particles between them. An AC voltage is applied to the reactor to generate partial or spark discharges. The results show that: (1) The CO/sub 2/ gas reduction rate increases with increasing flue gas residential time and primary applied power; (2) The CO/sub 2/ gas reduction rated increases with decreasing gas flow rate and dielectric constant ( xi /sub s/) of packed ferroelectric particles; (3) The CO/sub 2/ concentrations are reduced by up to 18000 p.p.m., and 108 g of CO/sub 2/ are reduced by 1 kWh of primary applied energy used in the packed bed reactor.<>
