ABSTRACT:
The invention relates to a process for producing alkylated aromatics, preferably ethylbenzene, in a multiple bed reactor in which at least two catalysts, each comprising a molecular sieve, are used in sequential beds. The first alkylation catalyst is selected to have a higher activity or alpha value than the subsequent alkylation catalyst.
