| Abstract/Summary |
The dynamics of adsorption and desorption of propene on γ-alumina has been studied by means of Cahn recording microbalances at temperatures between 180ºC and 380ºC. It was observed that only a part of propene is adsorbed strongly, whilst the rest is weakly adsorbed. The amount of adsorbed propene rst decreases with increasing temperature, but, starting from about 300ºC, this behaviour changes markedly, yielding again the higher extent of adsorption. A model of the process involving propene adsorption followed by its dimerization inside the sorbent pores has been suggested and tested by simulation and tting.
