The physicochemical properties of the partially spent catalyst Pt-Re-Cl/Al2O3 reforming of petroleum fractions (R- 98 UOP) have been studied. It has been found that during operation of the catalyst, a reduction of textural characteristics, chemical composition, partial phase transformation of alumina support, and accumulation of metallic impurities and carbon deposits take place. The DSC method has been found the presence on the surface of the catalyst of various types of carbonaceous deposits burnable at different temperatures. Their removal is complete at temperatures 500-550 °C.
