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 to nickel/aluminum-containing catalyst materials useful, for example, as reforming catalysts, processes for making them, and processes for using them in molten carbonate fuel cells. In one aspect, the disclosure provides a catalyst material including an alumina carrier in an amount in the range of about 5 wt % to about 75 wt %; and a mixed metal oxide in an amount in the range of about 25 wt % to about 95 wt %, the mixed metal oxide including at least about 90 wt % of oxides of nickel and aluminum, the mixed metal oxide having an atomic ratio of nickel to aluminum in the range of about 60:40 to about 90:10, the mixed metal oxide being substantially free of zirconium, in the form of a composite of the alumina carrier and the mixed metal oxide.

Reforming catalyst material and processes for making and using same

A system for removing CO, Hand CHfrom an anode waste gas stream from a fuel cell is disclosed. The two catalyst system may comprise a platinum/palladium catalyst and a copper/manganese catalyst. The anode waste stream comes in contact with the platinum/palladium catalyst prior to contacting the copper/manganese catalyst.

A catalytic water gas shift process at temperatures above about 450&#xb0; C. up to about 900&#xb0; C. or so wherein the catalyst includes rhenium deposited on a support, preferably without a precious metal, wherein the support is prepared from a high surface area material, such as a mixed metal oxide, particularly a mixture of zirconia and ceria, to which may be added one or more of a high surface area transitional alumina, an alkali or alkaline earth metal dopant and/or an additional dopant selected from Ga, Nd, Pr, W, Ge, Fe, oxides thereof and mixtures thereof.

Ultra high temperature shift catalyst with low methanation

A method for producing a substantially desulfurized a hydrocarbon fuel stream at temperatures less than 100&#xb0; C. The method includes providing a nondesulfurized fuel cell hydrocarbon fuel stream that may include water and passing the fuel stream sequentially through a zeolite Y adsorbent and a selective sulfur adsorbent. The zeolite Y adsorbent may be exchanged with copper ions. The method produces a substantially desulfurized hydrocarbon fuel stream containing less than 50 ppb sulfur.

Desulfurization system and method for desulfurizing a fuel stream

A water gas shift catalyst for use at temperatures above about 450&#xb0; C. up to about 900&#xb0; C. or so comprising rhenium deposited on a support, preferably without a precious metal, wherein the support is prepared from a high surface area material, such as a mixed metal oxide, particularly a mixture of zirconia and ceria, to which may be added one or more of a high surface area transitional alumina, an alkali or alkaline earth metal dopant and/or an additional dopant selected from Ga, Nd, Pr, W, Ge, Fe, oxides thereof and mixtures thereof.

The present development is a catalyst for use in water gas shift processes, a method for making the catalyst and a method of using the catalyst. The catalyst is composed of iron oxide, copper oxide, zinc oxide, alumina, and optionally, potassium oxide, and is produced using a hydrothermal synthesis process. The catalyst demonstrates surprising activity for conversion of carbon monoxide under high to moderate temperature shift reaction conditions.

Iron-based water gas shift catalyst

A strontium-doped, calcium-alumina nickel supported reforming catalyst is useful for reforming reactions when it is desired to generate a low H/CO ratio synthesis gas and to reduce coking. The catalyst can generate a synthesis gas having a H/CO ratio of less than about 2.3. The catalyst includes alumina, from about 0.3 wt. % to about 35 wt. % of calcium oxide, from about 0.1 wl % to about 35 wt. % of a strontium promoter, and about 0.5 wt. % to about 30 wt. % nickel. The support is prepared by a method wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.
