Abstract
PLATINUM-ON-ALUMINA reforming catalysts are widely used in the petroleum industry. Recent work in this laboratory has shown that catalysts containing soluble platinum more readily convert paraffins to aromatics1. Soluble platinum is that which will dissolve in either dilute hydrofluoric acid or acetylacetone. It is believed to exist as a compound involving the alumina support and the chloride present in the catalyst, and is in the plus-four valence state after solution in dilute hydrofluoric acid.
