The kinetics of ethane sorption by commercial 4A molecular sieve pellets has been investigated in a constant pressure microbalance system under isothermal conditions. Results show that micropore diffusion of ethane is the rate-limiting process, but diffusivities are much lower than for pure sieve crystals. Differences are apparently due to high-temperature steaming which must occur during pellet preparation, and not to heat stress or the presence of clay binder. Experimentally determined diffusivities can be used to predict fixed bed performance quite well.
