Abstract
The question of the mechanism of formation of carbonium ions on Lewis or Bronsted acid centres remains unclear. Studies of the chemical conv ersion of a model cumene hydrocarbon and also its chemisorption on a c racking catalyst by means of gas-liquid chromatography have shown that carbonium ions are formed from isothermally desorbable cumene chemiso rbed on Lewis acid centres. The proton sources are the OH groups chemi sorbed on the catalyst. (C) 1997 Elsevier Science Ltd. All rights rese rved.
