Process for regenerating a metathesis catalyst
An improved process for regenerating metathesis catalysts that comprise a compound of rhenium, molybdenum or tungsten on a porous substrate that consists of a refractory oxide and that has an acidic, neutral or basic nature, and an organometallic promoter that consists of an alkyl complex of tin or...

| Summary: | An improved process for regenerating metathesis catalysts that comprise a compound of rhenium, molybdenum or tungsten on a porous substrate that consists of a refractory oxide and that has an acidic, neutral or basic nature, and an organometallic promoter that consists of an alkyl complex of tin or lead is described. The regeneration comprises a selective extraction of the organometallic promoter followed by a calcination and a reimpregnation by the same promoter. |
