  • ALKYLAROMATIC CONVERSION CATALYST SYSTEM
    Publication number: 20220410131
    Abstract: An alkylaromatic conversion catalyst system having (a) a first catalyst composition having (i) a carrier which includes a binder composition prepared from a mixture having one or more oligomerized alkoxy silicates and one or more hydrolyzing agents; and a ZSM-5 zeolite; (ii) one or more metals chosen from the group consisting of Groups 6, 9, 10 and 11; and optionally, (iii) a Group 14 metal; and (b) a second catalyst composition having (i) a carrier which includes a refractory oxide binder and a zeolite selected from one or more of ZSM-5, ferrierite, ZSM-11, ZSM-12 and EU-1; (ii) one or more metals chosen from the group consisting of Groups 6, 9, 10 and 11; and optionally, (iii) a Group 14 metal.
