Abstract
Exchange reactions of cyclopentane (250 K) and of 2,2-dimethylpropane (322 K and above) with deuterium were studied using static reactors on a well-characterised series of silica-supported Rh–Ir catalysts containing 1.06 × 10–4 mol metal g–1. Hydrogenolysis of 2,2-dimethylpropane was carried out at 427 K. The initial product distributions from the exchange reactions showed little variation with catalyst composition but gave considerable information about adsorbed intermediates. The change of activity with catalyst composition for reactions of 2,2-dimethylpropane was interpreted in terms of ensembles – a small ensemble for exchange and a larger one for hydrogenolysis for which rhodium was 80 times more active than iridium.
