The invention relates to a process for alkylating a hydrocarbon feed which comprises contacting the hydrocarbon feed to be alkylated with an alkylation agent in the presence of a catalyst comprising a solid acid, a hydrogenation metal, and 1.5 - 6 wt% of water, measured as the loss on ignition at 600~C. The presence of 1.5 - 6 wt% of water results in a higher activity and a higher alkylate quality compared with a comparable but drier catalyst.

L'invention concerne un procédé d'alkylation d'une charge d'hydrocarbures qui consiste à mettre en contact ladite charge d'hydrocarbures à alkyler avec un agent d'alkylation en présence d'un catalyseur qui comprend un acide solide, un métal d'hydrogénation, et une teneur en eau comprise entre 1,5 et 6 % en poids, telle que mesurée par détermination de la perte par calcination à 600 ·C. La présence de 1,5 à 6 % en poids d'eau permet d'obtenir une activité plus élevée et un alkylat de qualité supérieure par rapport à un catalyseur comparable mais plus sec.
