Fuel reformation of Jet fuels offers a hydrogen-rich gas mixture for fuel cell applications.  One of the primary challenges of making pure hydrogen is the removal of H2S in the gas phase.  The H2S can poison reformer and fuel cell catalysts, even at parts per million levels.  To protect these catalysts, sorbent materials for removal of H2S must be used.      In this work, we prepared 3D network porous ZnO-based materials using hydrogel as a template and evaluated the performance for H2S removal versus commercial ZnO.  Other related samples of ZnO doped with transition-metals by the same synthetic route were also examined.  The adsorbents were tested with H2S gas containing 400 ppmw under simulated fuel processing conditions at 430 �C.  This presentation will focus on the preparation methods and the H2S adsorption characteristics of these materials.
