Abstract: Catalyst compositions comprising a zeolite and a mesoporous support or binder are disclosed. The mesoporous support or binder comprises a mesoporous metal oxide having a particle diameter of greater than or equal to 20 μm at 50% of the cumulative pore size distribution (d50). Also disclosed are processes for producing a mono-alkylated aromatic compound (e.g., ethylbenzene or cumene) which exhibit improved yield of the mono-alkylated aromatic compound using alkylation catalysts comprising one or more of these catalyst compositions.

Abstract: Disclosed are selectivated transalkylation catalyst compositions and methods of making the same. The selectivated transalkylation catalyst compositions have a zeolite framework structure of MWW, FAU, BEA*, or MOR, or mixtures thereof, and are selectivated with a selectivating solution. The selectivating solution includes a dissolved ion of at least one element in Group 1, Group 2, Group 15, Group 16, or Group 17 of the Periodic Table. Also disclosed are processes of producing ethylbenzene and cumene using the selectivated transalkylation catalyst compositions.

Abstract: 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 μm at 50% of the cumulative pore size distribution (d50), a pore volume of less than 1 cc/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.

Abstract: Catalyst composition which comprises a first zeolite having a BEA* framework type and a second zeolite having a MOR framework type and a mesopore surface area of greater than 30 m2/g is disclosed. These catalyst compositions are used to remove catalyst poisons from untreated feed streams having one or more impurities which cause deactivation of the downstream catalysts employed in hydrocarbon conversion processes, such as those that produce mono-alkylated aromatic compounds.

Abstract: The present disclosure relates to a process for producing a mono-alkylated aromatic compound using a treated catalyst made by a method of this invention is disclosed. The method comprises the steps of heating an untreated catalyst in the presence of a gaseous stream having a dew point temperature less than about 5° C. to form a treated catalyst. The treatment is effective to improve the activity and selectivity of the catalyst.
