Abstract

The present invention is a process for separating propylene and dimethylether from a mixture comprising propylene,
dimethylether, and propane. The mixture is passed through a bed of an adsorbent comprising a porous crystalline material having (i) diffusion time constants for dimethylether and propylene of at least 0.1 sec-1 , and (ii) a diffusion time constant for propane of than 0.02 of the diffusion time constants for dimethylether and propylene. The bed preferentially adsorbs propylene and dimethylether from the mixture. The adsorbed propylene and dimethylether are then desorbed from the bed.
