In our preliminary work we wanted to learn the effect of some metals on the product composition of the reformate in order to lower the aromatic content. Therefore we producted some trimetallic reforming catalysts by the modification of the reference catalysts is an industrially used 0.28% Pt-Sn/Al2O3 catalyst. The modification was carried out in aqueous solution of the added metal ions. The ions were reduced by the absorbed hydrogen. The produced five catalysts contain iridium, palladium, rhenium, tin and bismut as third metal besides platinum and tin. These catalysts were used in a test reactor under similar conditions as in industrial scale. The products were analysed by chromatography. In the light of the results it seems that the second metals lower the liquid yield. The C5+ product compositions is only slightly affected exept the bismuth modified catalyst.
