The capacity of the additives kaolin and zeolite 24A to capture
KCl vapours was investigated through carrying out a series of
thermogravimetric studies. It was found that both increasing reaction
temperature and time have negative effects on the fraction
of KCl retained in kaolin and zeolite 24A. Zeolite 24A and kaolin
could capture respectively 60% and 45% of the blended KCl as the
additive-KCl mixtures were heated at 900 C for 1 h. The overall KCl
capturing efficiency of the two additives decreased to respectively
50% and 43% as the reaction time increased to 12 h. At 1000 C, only
