The influence of metal dispersion on n-hexane reactions over platinum-alumina catalysts
The influence of metal dispersion on n-hexane reactions over platinum-alumina catalysts tests with catalysts containing 0.22-9.47% by wt platinum show that, generally, the product distribution does not change appreciably by going from black metal to high dispersion supported platinum. The selectivity expressed as isomerization plus dehydrocyclization/hydrogenolysis increases with dispersion as a result of increased dehydrocylization. The amounts of methylcyclopentane in the reaction products strongly increase with disperison. The 2-methylpentane to 3-methylpentane ratio however, is not affected by high or low dispersion. This seems to indicate that the dispersion of platinum does not modify the pathway of the isomerization reaction, which probably occurs through a cyclic intermediate.
