Abstract
Over the past few years, a flurry of interest has emerged in using
microwaves (MW) in chemical processes, such as catalyst synthesis,
reactions and separations. For example, Turner et al. have recently
studied the effects of MW heating on a binary mixture,
methanol/cyclohexane, adsorbed in siliceous zeolites FAU and MFI. They
found that the effect on sorption selectivity from conventional heating
can be reversed by applying MW radiation. However, because the MW
period is long compared to typical thermalization time scales, it is not
clear what microscopic energy distributions are responsible for the
reversed selectivities discussed above. In the present communication, we
focus on determining energy distributions in MW-driven zeolite-guest
systems from microscopic simulations.
