Title: Processes and catalysts for reforming of impure methane-containing feeds

Abstract

Processes and catalysts for producing hydrogen by reforming methane are disclosed, which afford considerable flexibility in terms of the quality of the reformer feed. This can be attributed to the robustness of the noble metal-containing catalysts described herein for use in reforming, such that a number of components commonly present in methane-containing process streams can advantageously be maintained without conventional upgrading (pretreating) steps, thereby improving process economics. This also allows for the reforming of impure reformer feeds, even in relatively small quantities, which may be characterized as complex gas mixtures due to significant quantities of non-methane components. A representative reforming catalyst comprises 1 wt-% Pt and 1 wt-% Rh as noble metals, on a cerium oxide support.

Noble metal catalysts and processes for reforming of methane and other hydrocarbons

Patent Marker, Terry L.; Linck, Martin B.; Wangerow, Jim; ...

Processes for converting methane and/or other hydrocarbons to synthesis gas (i.e., a gaseous mixture comprising H₂ and CO) are disclosed, in which at least a portion of the hydrocarbon(s) is reacted with CO₂. At least a second portion of the methane may be reacted with H₂O (steam), thereby improving overall thermodynamics of the process, in terms of reducing endothermicity (ΔH) and the required energy input, compared to “pure” dry reforming in which no H2O is present. Catalysts for such processes advantageously possess high activity and thereby can achieve significant levels of methane conversion at temperatures below those used conventionally undermore » « less

Cyclic process for producing methane with catalyst regeneration

Patent Frost, Albert C.; Risch, Alan P.

Carbon monoxide-containing gas streams are passed over a catalyst capable of catalyzing the disproportionation of carbon monoxide so as to deposit a surface layer of active surface carbon on the catalyst essentially without formation of inactive coke thereon. The surface layer is contacted with steam and is thus converted to methane and CO.sub.2, from which a relatively pure methane product may be obtained. For practical commercial operations utilizing the two-step process of the invention of a cyclic basis, nickel, cobalt, ruthenium, thenium and alloys thereof are especially prepared for use in a metal state, with CO disproportionation being carried outmore » « less
