1. An adsorbent composition comprising a bismuth material, a promoter, and a support, wherein the support comprises particles having a particle size of from about 1 μm to 10 mm, wherein the bismuth material and the promoter are each dispersed within pores of the support via incipient-wetness impregnation of precursors of the bismuth material and the promoter onto the support, wherein the promoter comprises a silicon material or a tungsten material, and wherein:
the bismuth material is present as bismuth oxide from about 2 wt % to about 20 wt % on a bismuth metal basis, based on the total weight of the adsorbent composition,
the promoter is present from about 1 wt % to about 11 wt %, based on the total weight of the adsorbent composition, and
the balance of the weight of the adsorbent composition consists essentially of the support, the support being selected from a titanium oxide, an aluminum oxide, activated carbon, or a molecular sieve.
