A bimetallic supported catalyst with a strong interaction between a metal of group viii and tin and its use for a catalytic refo optimization processes

摘要

Describes a new supported bimetallic catalyst containing a group viii metal, such as platinum, tin, at least a portion of which is in a strong interaction with the metal of group viii in the catalyst to the reduced state. The catalyst of the invention contains, in the partially oxidized state at least 10% of tin in the form of a species of tin reduced to the state of oxyadtion 0, the said species with a displacement isomeric between 0 and 80 and 2, 60 mm / s and a burst quadripole between 0, 65 and 2, 00 mm / s. the invention also relates to the preparation of the catalyst, as well as the processes using the catalyst for the conversion of hydrocarbons in aromatic compounds, such as gasolines reforming process and the process of production of aromatics.
