Hayashi, T Lee, TG Hazelwood, M Hedrick, E Biswas, P 2024-01-21T14:04:33Z 2024-01-21T14:04:33Z 2021-09-01 2000-06 1047-3289 https://pubs.kist.re.kr/handle/201004/141375 The use of activated carbon fiber (ACF) filters for the capture of particulate matter and elemental Hg is demonstrated. The pressure drop and particle collection efficiency characteristics of the ACF filters were established at two different face velocities and for two different aerosols: spherical NaCl and combustion-generated silica particles. The clean ACF filter specific resistance was 153 kg m(-2) sec(-1). The experimental specific resistance for cake filtration was 1.6 x 10(6) sec(-1) and 2.4 x 10(5) sec(-1) for 0.5- and 1.5-mu m mass median diameter particles, respectively. The resistance factor R was approximately 2, similar to that for the high-efficiency particulate air filters. There was a discrepancy in the measured particle collection efficiencies and those predicted by theory. The use of the ACF filter for elemental Hg capture was illustrated, and the breakthrough characteristic was established. The capacity of the ACF filter for Hg capture was similar to other powdered activated carbons.
