Abstract
Bimetallic Ni-Rh/gamma-Al2O3 catalysts with various total metal conten ts and nickel mole fractions have been used in n-butane hydrogenolysis . Both the total reaction rate and the selectivity for ethane formatio n are strongly influenced by the two parameters as well as by the redu ction temperature. Rather unexpectedly, an addition of small quantitie s of nickel to Rh/gamma-Al2O3 catalysts increases their ability for ce ntral C-C bond rupture, in spite of the tendency of this metal to spli t terminal bonds in hydrocarbons.
