Abstract
The invention relates to a catalyst comprising a support, at least one noble metal M, tin, phosphorus and ytterbium, the content of phosphorus element being greater than or equal to 0.2% by weight and less than 0.4% by weight, and the content of ytterbium being less than or equal to 1% by weight relative to the mass of the catalyst. The invention also relates to the process for preparing the catalyst and to the use thereof in reforming.
Claims21
A catalyst comprising:
- a support, at least one noble metal M, tin, phosphorus, and ytterbium,
- wherein the content of phosphorus element is greater than or equal to 0.2% by weight and less than 0.4% by weight relative to the mass of the catalyst, and the content of ytterbium is at least 0.1% by weight and less than or equal to 1% by weight relative to the mass of the catalyst.
A catalyst composition selected from the following:
