Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: — with international search report (Art. 21(3)) (54) Title: METHODS FOR REMOVING IMPURITIES FROM A HYDROCARBON STREAM AND THEIR USE IN AROMATIC ALKYLATION PROCESSES (57) : Methods for removing impurities from a hydrocarbon stream using a guard bed material are disclosed. The guard bed material includes compositions which comprises a zeolite and a mesoporous support or binder. The zeolite has a Constraint Index of less than 3. The mesoporous support or binder comprises a mesoporous metal oxide having a particle diameter of greater than or equal to 20 tm at 50% of the cumulative pore size distribution (d 5 0), a pore volume of less than lcc/g, and an alumina content of greater than 75%, by weight. Also disclosed are processes for producing mono-alkylated aromatic compounds (e.g., ethylbenzene or cumene) using impure feed streams that are treated by the disclosed methods to remove impurities which act as catalyst poisons to downstream alkylation and/or transalkylation catalysts.
