Catalytic reactions of partial methane oxidation

On the Induction Period of Methane Aromatization over Mo-Based Catalysts

“…It is well known that fresh molybdenum carbide or nitride is very active and will spontaneously combust when exposed to air (27). Thus, it is not difficult to imagine that it will react with a trace amount of oxygen contained in CH 4 during the 1 h flushing before TPSR. Therefore, the molybdenum carbide may be oxidized, leading to the production of CO 2 /CO during the TPSR-MS and to the recarburization into pure molybdenum carbide.…”

“…Different approaches have been developed in order to get a better and efficient utilization of natural gas, such as two-step transformation of methane into C2 hydrocarbons over Pt or Ru catalysts (2,3) and selective oxidation of methane to methanol (4). However, it is still impractical to put most of these methods into industrial use due to their relatively low yields 1 To whom correspondence should be addressed.…”

Selective methane oxidation over promoted oxide catalysts

“…While methane makes an excellent gaseous fuel, it is desirable to convert it to higher molecular weight products for transportation, storage, and for utilization as chemical feedstocks. (14). Therefore, the literature will not be extensively reviewed here.…”
