To synthesize polymer-grade propylene from bioethanol containing an organosulfur compound such as dimethylsulfide (DMS) or dimethylsulfoxide (DMSO), we examined the adsorptive desulfurization of propylene employing a commercial activated alumina. Since it was found that both DMS and DMSO were mainly converted to hydrogen sulfide during the catalytic conversion of ethanol to propylene over HZSM-5 zeolite, the performance of the adsorbent was evaluated by measuring a packed-bed breakthrough curve for the adsorption of hydrogen sulfide in gaseous propylene. As a result of the adsorptive desulfurization, the concentration of hydrogen sulfide in propylene could be reduced to less than 10 ppb.
