oa South African Journal of Chemistry - The adsorption of water vapour on silica-alumina treated with potassium chloride

Volume 19, Issue 2
  • ISSN : 0379-4350



The adsorption of water vapour on silica-alumina catalyst samples, some of which had been pre-treated with potassium chloride, has been investigated at 30�C. The pre-treatment had no apparent effect on the monolayer adsorption characteristics, but a significant increase in adsorption occurred at higher coverage The results are discussed in terms of patches of potassium chloride formed on the surface.
