Abstract

The total concentrations of reactants and products within a flow-through reactor can be monitored as a function of both position and time by detecting gamma photons arising from the radioactive positron decay of injected 11C nuclei. The method was demonstrated by directly observing catalyst preconditioning and deactivation of a Pt/H-mordenite catalyst bed during the industrially important hexane hydroisomerization reaction.
