Abstract: A process is described for producing a catalyst composition comprising an iridium component dispersed on a support. In the process, silica-containing support is treated with an iridium compound and an organic compound comprising an amino group to form an organic iridium complex on the support. The treated support is then heated in an oxidizing atmosphere at a temperature of about 325° C. to about 475° C. to partially decompose the organic metal complex on the support. The treated support is then heated in a reducing atmosphere at a temperature of about 350° C. to about 500° C. to convert the partially decomposed organic iridium complex into the desired iridium component.

The methods include performing transalkylation where at least a portion of the feed to the transalkylation process is in the liquid phase. Optionally, the transalkylation conditions can correspond to conditions where a continuous liquid phase is present within the reaction environment. Some embodiments include liquid phase transalkylation processes for naphthalene-containing feedstock streams.
