Selectivity of chromium-aluminum catalysts in dehydrogenation of n-undecane

Conclusions

  1. 1.

    The selectivities of the chromium-aluminum catalysts studied in the dehydrogenation of n-undecane with the same conversions of the alkane are lowered when K2O is added to them, as well as when the reaction medium is diluted with N2. They are increased by dilution with H2; selectivity is determined by the temperature and the hydrocarbon feed rate, and is independent of the phase composition of the original Al(OH)3.

  2. 2.

    The principles governing the dehydrogenation of n-undecane are similar to those observed in the dehydrogenation of n-hexane but the selectivity of the chromium-aluminum catalyst in the dehydrogenation of n-undecane is lower.
