Abstract

n-Hexane and n-nonane were reacted on Pt black, 6% Pt/SiO2, 0.8% Pt/KL zeolite and a 0.6% industrial Pt/Al2O3 catalyst. Selectivities were compared at ∼10% conversion. After reaction, the catalyst was exposed to H2 and the hydrocarbons leaving the catalysts were analyzed. The amount of hydrocarbons left the catalysts decreased in the sequence Pt black> Pt/SiO2> Pt/KL>Pt/Al2O3. The composition of removed hydrocarbons gave important - although indirect - information on the possible state of "hydrocarbonaceous deposits" during catalysis.
