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.

[object Object]

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.

Use of a catalyst composition comprising a metal selected from the group consisting of ruthenium, rhodium, nickel and combinations thereof, on a support selected from the group consisting of a beta-zeolite, mordenite and faujasites, is taught for carbon oxide methanation reactions for fuel cells. Specifically, when a mixture of gases containing hydrogen, carbon dioxide, carbon monoxide, and water is passed over the catalyst in a reaction zone having a temperature below the temperature at which the shift reaction occurs and above the temperature at which the selective methanation of carbon monoxide occurs, the catalyst efficiently facilitates the selective hydrogenation of carbon monoxide using Hthat is present in the reformate and reduces the concentration of the CO to levels equal to or less than about 50 ppm and demonstrates a carbon monoxide (CO) methanation selectivity of greater than about 50%.

Catalyst for the conversion of carbon monoxide

A catalyst that can be used for the production of hydrogen from hydrocarbon fuels in steam reforming processes contains an active metal of, e.g., at least one of Ir, Pt and Pd, on a catalyst support of, e.g., at least one of monoclinic zirconia and an alkaline-earth metal hexaaluminate. The catalyst exhibits improved activity, stability in both air and reducing atmospheres, and sulfur tolerance.

Catalyst for hydrogen generation through steam reforming of hydrocarbons

A method for producing a substantially desulfurized hydrocarbon fuel stream at temperatures less than 100&#xb0; C. including providing a nondesulfurized fuel cell hydrocarbon fuel stream and passing the fuel stream through a sulfur adsorbent system containing a specialized sulfur adsorbent containing hydrated alumina to produce a substantially desulfurized hydrocarbon fuel stream.

Sulfur adsorbent, desulfurization system and method for desulfurizing

A promoted calcium-alumina supported reforming catalyst that is particularly useful for reforming reactions where low H/CO ratio synthesis gas, such as less than 2.3 is generated directly is disclosed. The catalyst comprises from about 25 wt % to about 98 wt % alumina, from about 0.5 wt % to about 35 wt % calcium oxide, from about 0.01 wt % to about 35 wt % of a promoter, and from about 0.05 wt % to about 30 wt % of an active metal. The promoter is selected from the group consisting of titanium, zirconium, yttrium, niobium, elements of the lanthanum-series, such as, without limitation, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, ytterbium, and combinations thereof. The active metal is selected from the group consisting of nickel, cobalt, rhodium, ruthenium, palladium, platinum, iridium and combinations thereof as active metal, wherein the calcium oxide is combined with the alumina to form aluminum-rich calcium aluminates.

Promoted calcium-aluminate supported catalysts for synthesis gas generation

Process for the preparation of promoted calcium-aluminate supported catalysts

A process for the preparation of water gas shift catalyst is described. The process includes mixing a copper salt and a zinc salt with an aluminum component in a solution, precipitating a precipitate from the solution, drying an forming the precipitate into the water gas shift catalyst. In an alternate process the aluminum component is prepared separately from the solution of the copper salt and the zinc salt prior to the mixing of the components. After the components are mixed a precipitate is precipitated from the solution, the precipitate is dried and formed into the catalyst.

Process for production of a water gas shift catalyst

A process for catalytic reforming of a hydrocarbon feed stream containing HO, CO, CHand CO at levels such that the HO/CHis less than 0.8 and the CO/CHis greater than 0.5 and the feed stream further contains quantities of sulfur compounds up to about 20 ppm. The catalyst used in this process contains from about 0.5 percent to about 25 percent by weight of a calcium compound additive, from about 2 percent to about 30 percent by weight nickel, and from about 25 percent to about 98 percent by weight of an aluminum compound carrier, wherein substantially all of the calcium is combined with the alumina. The reforming process can be utilized to produce syngas, especially low hydrogen to carbon monoxide ratio syngas for applications such as iron ore reduction.
