摘要:
An alkylaromatics isomerisation catalyst, which catalyst comprises at least 50 wt% of an inorganic binder; at least 0.01 wt% of a Group VIII metal and 1 - 9 wt % ZSM- 12 zeolite wherein the silica to alumina molar ratio (SAR) of the ZSM- 12 zeolite is in the range of from 60 to 200, and a process for the isomerisation of alkylaromatics to provide a reaction mixture, said process comprising contacting a hydrocarbon stream comprising alkylaromatics with such catalyst.
摘要:
A catalyst composition which comprises: a) a carrier which comprises at least 30 wt% of a binder selected from silica, zirconia and titania; at least 20 wt% of a pentasil zeolite, having a bulk silica to alumina ratio in the range of from 20 to 150 and being in its H+ form; and less than 10 wt% of other components, all percentages being on the basis of total carrier; b) platinum in an amount in the range of from 0.001 to 0.1 wt%, on the basis of total catalyst; and c) tin in an amount in the range of from 0.01 to 0.5 wt%, on the basis of total catalyst; its preparation and use; are provided.
