1. A process for producing a zinc titanate reactive adsorbent comprising electrospinning a solution, the solution comprising an organic zinc-containing compound and a titanium-containing compound wherein the organic zinc-containing compound comprises zinc acetate dihydrate and the titanium-containing compound comprises titanium (IV) isopropoxide,
wherein the zinc titanate adsorbent comprises multiphase, polycrystalline nanofibers comprising ZnTiO 3 , ZnO, TiO 2 , and Zn 2 TiO 4 , and having a diameter ranging from 350 to 800 nm.
2. The process of claim 1 , further comprising a sulfidation step operated at a sulfidation temperature and a regeneration step operated at a regeneration temperature, wherein the sulfidation temperature and the regeneration temperature are within 5° C. of each other.
3. The process of claim 2 wherein the sulfidation temperature and the regeneration temperature are the same.
