INVESTIGATION OF DECOMPOSITION CATALYSTS FOR 98% HYDROGEN PEROXIDE
Abstract
Heterogeneous decomposition catalysts for 98% H2O2 were evaluated in both laboratory and engineering tests. The laboratory program screened thirty- three metals and alloys and eighteen catalyst pellets for catalytic activity and thermal stability at the high (1740 F or higher) decomposition temperatures of 98% H2O2. Silver and silver palladium alloy screens with samarium surface activations were the best catalysts, but only the silver-palladium catalyst exhibits the required thermal stability. Manganese, cobalt, lead, and barium oxides were also very active and thermally stable, but were not suitably incorporated into catalyst packs. The catalytic activity of the remaining materials was insufficient for rocket applications in the forms tested. Catalyst packs containing the silver - 30% palladium catalyst screens were tested in 22 and 40 pound thrust motors and a 3/4-inch internal diameter gas generator. Inlet and chamber pressures and temperatures, flow rates, catalyst pack temperatures, thrusts, and starting responses were measured. Pack configurations were tested with and without silver or silver-5% palladium screens in the inlet section and with 40 or 20 mesh screens in the inlet and 20 or 14 mesh screens in the exhaust section. The silver-30% palladium catalyst gave good performance in gas generator tests up to 0.8 lb/sec flow rates and 1500 psia chamber pressures.
