A process for preparing a transalkylation catalyst, the catalyst itself, and a transalkylation process for using the catalyst are herein disclosed. The catalyst comprises rhenium metal on a solid-acid support such as mordenite, which has been treated with a sulfur-based agent and/or a reducing agent under substantially dry reducing conditions including a temperature greater than 350~C. Such treatment reduces the amount of methane produced by metal hydrogenolysis in a transalkylation process wherein heavy aromatics like A9+ are reacted with toluene to produce xylenes. Reduced methane production relative to total light ends gas production results in lower hydrogen consumption and lower reactor exotherms.

La prEsente invention concerne un procEdE pour prEparer un catalyseur de transalkylation, le catalyseur même et un procEdE de transalkylation pour utiliser le catalyseur. Le catalyseur comprend du rhEnium sur un support solide-acide, tel que la mordEnite, qui a EtE traitE avec un agent A base de sulfure et/ou un rEducteur, dans des conditions de rEduction considErablement sEches, comprenant une tempErature supErieure A 350 ºC. Un tel traitement rEduit la quantitE de mEthane produit par hydrogEnolyse de mEtaux dans un processus de transalkylation, dans lequel les aromatiques lourds, tels que l'A9+, sont mis en réaction avec le toluEne pour produire des xylEnes. La production rEduite de mEthane par rapport A la production totale de fractions lEgEres de gaz entraIne une consommation plus faible d'hydrogEne et des tempEratures exothermiques de rEacteur plus faibles.
