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.
