크로마토그라피법에 의한 대형세공 입자의 물질전달 파라미터의 추산
Estimation of Mass Transfer Parameters of Large-Pore Particles by Chromatography
초록
크로마토그라피법으로써 column에 충전된 대형세공 입자의 물질전달 파라미터를 측정하였다. 입자와 column의 굴곡도는 구속흐름 크로마토그라피법으로 측정하였으며, 흡착평형상수는 구속흐름 및 연속흐름 크로마토그라피법으로 측정하였다. 입자외부 및 입자내부 확산계수는 구속흐름 크로마토그라피법으로써, 흡착평형상수는 연속흐름 크로마토그라피법으로써, 보다 효과적으로 측정할 수 있었다.
Chromatographic technique was used to determine mass transfer parameters of large-pore particles in packed columns. Particle and column tortuosity factors were determined by the arrested-flow gas chromatography, and adsorption equilibrium constant by the arrested-flow gas chromatography and the continuous-flow gas chromato-graphy. Extraparticle and intraparticle diffusivities could be more effectively determined by the arrested-flow gas chromato-graphy. Extraparticle and intraparticle diffusivities could be more effectively determined by the arrested-flow gas chromato-graphy. Extraparticle and intraparticle diffusivities could be more effectively determined by the arrested-flow gas chro-matography, but adsorption equilibrium constant more effectively by the continuous-flow gas chromatography.
