Abstract
The dehydrocyclization activity of supported platinum, molybdenum and rhenium catalysts was studied by determining the toluene yield from n-heptane as a function of temperature and metal concentration in the catalyst. The support was 100 to 200 mesh alumina. Metal concentrations of 0.01% to 1.0% platinum, 0.1% to 2.0% molybdenum and 0.1% to 2.5% rhenium were studied in the temperature range from 500° to 600° C. Platinum was shown to be superior to both molybdenum and rhenium at all temperatures and metal concentrations investigated. The rhenium data were somewhat erratic, but showed rhenium to be a poor dehydrocyclization catalyst. The apparatus, which produced hydrocarbon vapor for the feed stream by passing hydrogen gas through a liquid bydrocarbon, was shown to give qualitative data.
