Catalyst with good accessibility containing elements of the groups 8, 9 and 10 and the use thereof in a process for the dehydrogenation of paraffins

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.
