Embodiments provided herein are compositions directed to porous iron oxides, which are suitable for removing hydrogen sulfide and other sulfur-containing organic contaminants from hydrocarbon streams, and in which the iron oxide component of the composition contains both maghemite and hematite phases, with maghemite forming the greater portion of these phases. In some embodiments, magnetite, aluminum oxide, alumina silicate, and a binder comprised of an organic substance are homogenized, followed by calcining which burns away the organic and converts magnetite to a mix of maghemite and hematite.

Iron oxide absorbent compositions

The present disclosure relates generally to ceramic materials suitable for use as catalyst support materials, catalysts using such materials and methods for using them, such as methods for converting sugars, sugar alcohols, glycerol, and bio-renewable organic acids to commercially-valuable chemicals and intermediates. One aspect of the invention is a ceramic material including zirconium oxide and one or more metal oxides selected from nickel oxide, copper oxide, cobalt oxide, iron oxide and zinc oxide, the ceramic material being at least about 50 wt. % zirconium oxide. In certain embodiments, the ceramic material is substantially free of any binder, extrusion aid or additional stabilizing agent.
