The dehydrogenation and hydrogenolysis of n-butane (n-C4) over a Ru-Al2O3 catalyst (0.849 w/w% Ru) have been studied at 490 °C at different time factors. Some runs have also been made on pure γ-Al2O3 at 490 °C and on Ru-black at temperatures between 100 and 490 °C, feeling n-butane and hydrogen. The analysis of the selectivity vs. time factor factor allows to prove that the initial reactions taking place are n-C4 dehydrogenation to 1-butene and 2-butenes and skeletal isomerization to isobutane. The initial molar selectivity to the n-butenes reaches about 70%. A qualitative reaction scheme is proposed.

Abstract

The dehydrogenation and hydrogenolysis of n-butane (n-C4) over a Ru-Al2O3 catalyst (0.849 w/w% Ru) have been studied at 490 °C at different time factors. Some runs have also been made on pure γ-Al2O3 at 490 °C and on Ru-black at temperatures between 100 and 490 °C, feeling n-butane and hydrogen. The analysis of the selectivity vs. time factor factor allows to prove that the initial reactions taking place are n-C4 dehydrogenation to 1-butene and 2-butenes and skeletal isomerization to isobutane. The initial molar selectivity to the n-butenes reaches about 70%. A qualitative reaction scheme is proposed.
