Abstract
n-Hexane and n-nonane were reacted on Pt black, 6% PtSiO2, 0.8% Pt/KL zeoli te and a 0.6% industrial Pt/Al2O3 catalyst. Selectivities were compared at similar to 10% conversion. After reaction, the catalyst was exposed to H-2 and the hydrocarbons leaving the catalysts were analyzed. The amount of hyd rocarbons left the catalysts decreased in the sequence Pt black> Pt/SiO2> P tKL>Pt/Al2O3. The composition of removed hydrocarbons gave important - alth ough indirect information on the possible state of "hydrocarbonaceous depos its" during catalysis.
