EFFECT OF CRYSTAL SIZE DISTRIBUTION ON CHROMATOGRAPHIC PEAKS IN MOLECULAR SIEVE COLUMNS

Abstract

The effect of zeolite crystal size distribution on sorption has been studied for a packed bed subjected to a pulse input. The swelling crystal approach proposed recently has been used lo incorporate the effect of size distribution. The effluent concentration pulse and its moments show significant dependence on size distribution. Use of conventional moment analysis for uniform particles is shown to introduce significant error in the estimates of sorption parameters. A simple technique is suggested to rectify these estimates for size distribution effects.
