A catalyst composition comprises (a) a MCM-22 family molecular sieve; and (b) a binder, wherein the MCM-22 family molecular sieve is characterized by an average crystal agglomerate size of less than or equal to 16 microns. The catalyst composition may further have a second molecular sieve having a Constraint Index of less than 12, e.g., less than 2. Examples of molecular sieve useful for this disclosure are a MCM-22 family molecular sieve, zeolite Y, and zeolite Beta. The catalyst composition may be used for the process of alkylation or transalkylation of an alkylatable aromatic compound with an alkylating agent.

La présente invention concerne une composition catalytique qui comprend (a) un tamis moléculaire de la famille MCM-22 ; et (b) un liant, le tamis moléculaire de la famille MCM-22 étant caractérisé par une taille moyenne d'agglomérat cristallin de moins de ou égale à 16 microns. La composition catalytique peut en outre avoir un second tamis moléculaire ayant un indice de contrainte de moins de 12, par exemple, moins de 2. Des exemples de tamis moléculaire utile pour cette description sont un tamis moléculaire de la famille MCM-22, la zéolithe Y, et la zéolithe béta. La composition catalytique peut être utilisée pour le procédé d'alkylation ou de transalkylation d'un composé aromatique susceptible d'être alkylé avec un agent d'alkylation.
