  • Patent number: 11059034
    Abstract: Process for dealkylation of alkylaromatic compounds which process comprises contacting an alkylaromatic feedstock with i) a first catalyst comprising a) a carrier comprising of from 20 to 70 wt. % of refractory oxide binder and of from 30 to 80 wt. % of dealuminated ZSM-5 having a crystallite size of from 500 to 10,000 nm and a silica to alumina molar ratio (SAR) of from 20 to 100; b) of from 0.001 to 5 wt. % metal chosen from the group consisting of Groups 6, 9 and 10; and optionally c) up to 0.5 wt. % of a Group 14 metal, and ii) a subsequent catalyst comprising a) a carrier comprising of from 20 to 70 wt. % of refractory oxide binder and of from 30 to 80 wt. % of ZSM-5 having a crystallite size of from 3 to 100 nm and a SAR of from 20 to 200; b) of from 0.001 to 5 wt. % of metal chosen from the group consisting of Groups 6, 9 and 10; and optionally c) up to 0.5 wt. % of a Group 14 metal.

  • Patent number: 10773249
    Abstract: A process of preparing a catalyst composition which process comprises the steps of (a) treating ZSM-5 zeolite with an alkaline solution having a pH of at least (8) followed by ion exchange to obtain a treated zeolite, (b) extruding a mixture of the treated zeolite and binder and contacting the zeolite with a fluorocompound containing solution, (c) increasing the temperature of the extrudates obtained in step (b) to at least 200° C., and (d) combining the extrudates obtained in step (c) with one or more metals selected from the group consisting of Group (10) and (11) of the IUPAC Periodic Table of Elements and a process for the conversion of an aromatic hydrocarbons containing feedstock using a catalyst composition prepared by such process.
