CATALYSEUR COMPRENANT UN ELEMENT DES GROUPES 8,9 ET 10 PRESENTANT UNE BONNE ACCESSIBILITE ET SON UTILISATION DANS UN PROCEDE DE DESHYDROGENATION DES PARAFFINES

摘要

The catalyst composition includes elements from groups 14 and 13 and an alkali or alkaline earth metal apart from a metal of group 8, 9 or 10, and also a small amount of a halogen(0 - 0.2%) The accessibility(i.e. the amount of element accessible to the charge to be converted relative to the total amount of group8, 9 or 10 element) of the group 8,9, or 10 metal is over 50%. Independent claims are also included for the process of preparation and use of the catalyst.
