TLDR
The interaction of methane with metal catalysts has received less attention than that of hydrocarbons containing two or more carbon atoms as mentioned in this paper, but it is interesting because its electronic structure resembles that of a rare gas and it possesses high symmetry and small reactivity.Abstract:
The interaction of methane with metal catalysts has received less attention than that of hydrocarbons containing two or more carbon atoms [1]. Yet methane is interesting because its electronic structure resembles that of a rare gas and it possesses high symmetry and small reactivity. Also, it is the most stable of the alkanes and one of the few thermodynamically stable at room temperature. The temperature at which methane should spontaneously decompose (δG° = 0) is 570°C [2] and its reactions may give valuable information [4].read more

Carbon Deposition in Steam Reforming and Methanation
TL;DR: In this article, the authors investigated the causes of deactivation of supported metal catalysts by carbon or coke formation, and found that deactivation can occur due to fouling of the metal surface, blockage of catalysts pores and voids, and actual physical disintegration of the catalyst support.

Catalytic combustion of methane over palladium-based catalysts
TL;DR: In this paper, a review of the literature on supported Pd catalysts for combustion of methane is presented, taking into consideration the oxidation/reduction mechanisms for supported palladium, poisoning, restructuring, the form of oxygen on the surface, methane activation over Pd and PdO phases, and transient behavior.

Partial Oxidation of Methane
R. Pitchai,Kamil Klier +1 more
TL;DR: Partial oxidation is a widely used process to convert hydrocarbons and alcohols to valuable oxygen-containing chemicals as discussed by the authors, however, the direct utilization of these reactions for the manufacture of formaldehyde and methanol has remained extremely difficult.

Structure sensitivity of methane oxidation over platinum and palladium
TL;DR: A series of supported platinum and palladium catalysts were tested for methane oxidation at 260 to 370°C, 50 Torr methane, 110 Torr oxygen, 900 Torr helium, and conversions below 2%.
