A process for alkylating aromatic hydrocarbons is provided. The present invention implements a process for alkylating aromatic hydrocarbons, and more particularly a process for making paraxylene by alkylation of benzene and / or toluene with methanol and / or dimethyl ether, and said process. This improvement includes a multi-stage injection of reactants, which are separated by structural packing to provide gas phase backmixing, bypassing, and bubble size At least one is designed to be minimized.
