Abstract: A catalyst composition comprises a self-bound zeolite and a Group 12 transition metal selected from the group consisting of Zn, Cd, or a combination thereof, the zeolite having a silicon to aluminum ratio of at least about 10, the catalyst composition having a micropore surface area of at least about 340 m2/g, a molar ratio of Group 12 transition metal to aluminum of about 0.1 to about 1.3, and at least one of: (a) a mesoporosity of greater than about 20 m2/g; (b) a diffusivity for 2,2-dimethylbutane of greater than about 1×10−2 sec−1 when measured at a temperature of about 120° C. and a 2,2-dimethylbutane pressure of about 60 torr (about 8 kPa).

Abstract: A catalyst composition includes a zeolite, a binder, and a Group 12 transition metal selected from the group consisting of Zn, Cd, or a combination thereof, the zeolite having a silicon to aluminum ratio of at least about 10, the catalyst composition comprising about 50 wt % or less of the binder based on a total weight of the catalyst composition, the catalyst composition having a micropore surface area of at least about 340 m2/g, a molar ratio of Group 12 transition metal to aluminum of about 0.1 to about 1.3, and at least one of (a) a mesoporosity of greater than about 20 m2/g; (b) a diffusivity for 2,2-dimethylbutane of greater than about 1×10−2 sec−1 when measured at a temperature of about 120° C. and a 2,2-dimethylbutane pressure of about 60 torr (about 8 kPa).

Abstract: A catalyst composition comprising a zeolite, an alumina binder, and a Group 12 transition metal selected from Zn and/or Cd, the zeolite having a Si/Al ratio of at least about 10 and a micropore surface area of at least about 340 m2/g, the catalyst composition comprising about 50 wt % or less of the binder, based on a total weight of the catalyst composition, and having a micropore surface area of at least about 290 m2/g, a molar ratio of Group 12 transition metal to aluminum of about 0.1 to about 1.3, and at least one of: a mesoporosity of about 20 m2/g to about 120 m2/g; a diffusivity for 2,2-dimethylbutane of greater than about 1×10−2 sec−1 when measured at a temperature of about 120° C. and a 2,2-dimethylbutane pressure of about 60 torr (8 kPa); and a combined micropore surface area and mesoporosity of at least about 380 m2/g.
