The study of supported manganese catalysts in the course of the oxidative coupling of methane

Characterization of Mn–Na2WO4/SiO2 and Mn–Na2WO4/MgO catalysts for the oxidative coupling of methane

“…Detailed investigations have examined the influence of each component, i.e. Mn, Na and W, on the catalytic activity and selectivity [5][6][7][8][9][10], the effects of reaction pressure [11] and temperature plus CH 4 :O 2 ratio [12], and studies have been conducted to investigate support materials other than SiO 2 [13][14][15][16]. In addition, fluidized bed processing for large scale production has been tested using the Mn-Na 2 WO 4 /SiO 2 catalyst [17][18].…”

“…Full range XRD patterns obtained from fresh and spent Mn-XRD patterns obtained from (a) Na 2 WO 4 /n-SiO 2 plus fresh and spent Mn-Na 2 WO 4 /nSiO 2 and (b) Mn-Na 2 WO 4 /n-MgO catalysts focused on a smaller range of 2 values(15 …”
