A metal-modified alkylation catalyst including a metal/zeolite is provided where the metal is one or two selected from the group consisting of yttrium and a rare earth of the lanthanide series other than cerium. Where two metals are used, one may be Ce or La. The metal-promoted zeolite is useful as a molecular sieve aromatic alkylation catalyst for the production of ethylbenzene by the ethylation of benzene in the liquid phase or critical phase. An alkylation product is produced containing ethylbenzene as a primary product with the attendant production of heavier alkylated by-products of no more than 10-60 wt% of the ethylbenzene.

L'invention concerne un catalyseur d'alkylation à métal modifié qui comprend un système métal/zéolithe, ledit métal étant un ou deux métaux sélectionné(s) dans le groupe constitué par l'yttrium et une terre rare du groupe des lanthanides, autre que le cérium. Si deux métaux sont utilisés, l'un des deux est Ce ou La. La zéolithe à promoteur métallique sert de catalyseur d'alkylation aromatique de tamis moléculaire en vue de la production d'éthylbenzène, par l'éthylation de benzène en phase liquide ou critique. L'invention permet de produire un produit d'alkylation contenant de l'éthylbenzène comme produit primaire, et des sous-produits alkylés plus lourds à raison de 10-60 % en poids au maximum de l'éthylbenzène.
