Estimating the term…
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.
An aromatics alkylation catalyst composition for aromatics alkylation consisting of a zeolite and a mesoporous binder, said mesoporous binder is a mesoporous metal oxide which has a median particle size d50 of greater than or equal to 20 μm and a pore volume of less than 1 cc/g, said mesoporous metal oxide has an alumina content of greater than or equal to 75%, by weight, said mesoporous metal oxide comprises amorphous silica-alumina, said zeolite has a framework structure that includes one or more of BEA* and MWW, and wherein said catalyst composition has a surface area of less than or equal to 300 m2/g as measured by ASTM D4284.
