| description | Process for the preparation of styrene comprising the gas phase dehydration of 1-phenylethanol at elevated temperature in the presence of a dehydration catalyst in which the dehydration catalyst comprises shaped alumina catalyst particles having a surface area (BET) of from 80 to 140 M /g and a pore volume (Hg) of more than 0.65 ml/g.
L'invention concerne un procédé pour préparer du styrène comprenant la déshydratation en phase gazeuse de 1-phényléthanol à une température élevée, en présence d'un catalyseur de déshydratation, dans lequel le catalyseur de déshydratation comprend des particules catalytiques d'alumine formées, présentant une zone de surface (BET) comprise entre 80 et 140 m /g et un volume de pores (Hg) supérieur à 0,65 ml/g. |
