| Abstract: | The hydrogenation of 1,3-pentadiene into pentenes over the commercial 0.5% Pd/Al2O3 catalyst and over a new catalyst containing 1.0% Pd and 3.7% Ag (μ-catalyst) has been investigated. The new catalyst has
been prepared via the flameless wave conversion of cyclotrimethylenetrinitramine in a porous composite. The catalytic properties
of the new composite in the hydrogenation reaction depend on the hydrogen/1,3-pentadiene ratio and on the catalyst activation
temperature. The reaction conditions for selective 1,3-pentadiene hydrogenation have been optimized. The pentenes yield as
a function of temperature passes through a maximum at any H2/C5H8 ratio between 1 and 2. The 2-pentene/1-pentene ratio in the reaction products increases as the temperature is raised. |
