In this work, the process of OCM carried out over Mn-Na₂WO₄/SiO₂ integrated with selective oxidation over Ag/support was investigated. The effect of feed gas composition and OCM bed temperature as well as the position of Ag/support bed and additional oxygen injection before this bed were investigated. At optimal OCM conditions for the Mn-Na₂WO₄/SiO₂ catalyst (CH₄/O₂ = 3.75; V_tot = 77 cm³/min; T = 780°C), the injection of additional 4 cm3/min of oxygen into the bed of Ag/support (working at 250–300°C) leads to a preferential oxidation of CO to CO₂.

W pracy zbadano proces OCM w obecności Mn-Na₂WO₄/SiO₂ zintegrowany w jednym reaktorze z procesem selektywnego utleniania CO prowadzonym na katalizatorze Ag/nośnik. Zbadano wpływ zmiany parametrów prowadzenia procesu OCM, takich jak skład surowca i temperatury oraz efekt dodatku tlenu nad złoże Ag/nośnik. Wykazano, że w optymalnej temperaturze pracy złoża OCM (CH₄/O₂ = 3.75; V_tot = 77 cm³/min; T = 780°C) wprowadzenie dodatkowo 4 cm3/min tlenu nad złoże Ag/nośnik (pracującego w temp. 250–300°C) prowadzi do preferencyjnego utleniania CO do CO₂.
