Reforming Catalyst with Chelated Promoter

A process for preparing a catalyst suitable for naphtha reforming comprising a stannous tin component, a platinum-group metal component, and a rhenium component, having the stannous tin component uniformly distributed throughout a solid refractory oxide support, the process comprising:

• a) preparing a chelate-tin aqueous solution containing a chelating agent and a stannous tin compound;
• b) heating said chelate-tin solution for a time of about 5 minutes to about 5 hours at a temperature of about 40° to about 100° C.;
• c) preparing an acidic aqueous solution containing a platinum-group compound and a rhenium compound;
• d) impregnating a solid refractory oxide support with said acidic solution to give a first impregnated solid support;
• e) impregnating said first impregnated solid support with said chelate-tin solution to give a second impregnated solid support;
• f) calcining the second impregnated solid support at a temperature of about 300° to about 850° C. for a time of about 10 minutes to about 18 hours to give a calcined catalyst;
• and
• g) reducing the calcined catalyst at a temperature of about 300° to about 850° C. for a time of about 30 minutes to about 18 hours, under a reducing atmosphere, thereby providing said catalyst suitable for naphtha reforming.
