It is obvious that it is virtually impossible to vary the Pt{sup n{plus}}/Pt ratio and to keep all factors mentioned constant. Nevertheless, we have made an attempt to solve the title problem and, in view of the complexities it is not very surprising that only a limited success was achieved. The strategy was to study the skeletal reactions under such conditions that only (or mainly) Pt (or Pt{sup n{plus}} ) sites are important. This is expected to be the case in the {und L}ow {und T}emperature {und R}eactions (LTR) in the region 480-590{degree}K. After studying this region, we also studied hexane reactions at higher temperatures (HTR): 650-700{degree}D. In this temperature region, the consecutive reactions must be checked and it was decided to keep the ratio S(Pt)/F constant and to compare the catalysts at the same temperature and at conversions as low as possible. The results have to be analyzed then with regard to a possible role of acid sites.
