An experimental 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 the following: (1) the CO[sub 2] gas reduction rate increases with increasing flue gas residence time and primary applied power; (2) the CO[sub 2] gas reduction rate increases with decreasing gas flow rate and dielectric constant of packed ferroelectric particles; (3) the CO[sub 2] concentration is reduced by up to 18,000 ppm, and 108 g of CO[sub 2] are removed by 1 kWh of primary applied energy used in the packed-bed reactor.
