Catalytic oxidative coupling of methane to C\\(_2\\) hydrocarbon

TL;DRAbstract

In this work the direct conversion of methane to C\\(_2\\) hydrocarbons through the catalytic oxidative coupling reaction (nCH\\(_4\\) + y/2 0\\(_2\\) => C\\(_n\\)H\\(_{4n-2y}\\) + y H\\(_2\\)0) is investigated. The catalytic materials studied can be categorised as single chemical compounds, different loading of Li\\(_2\\)CO\\(_3\\) on MgO, various lithium salts on MgO, Li\\(_2\\)CO\\(_3\\) on various metal oxides, transition metal oxides on MgO and transition metal oxides on Li\\(_2\\)CO\\(_3\\)/Mg0 systems. Most of these materials were prepared by wet aggregation or impregnation methods and precalcined at 900\\(^o\\)C for 10 hours. Atomic absorption spectroscopy was used to determine the metal composition of these materials. Their nature after calcination was studied by SEM and X-ray Micro-Probe Analysis. Surface area measurements and XRD analysis were also performed on most of the catalytic materials. The nature of selected materials under conditions similar to the catalytic stud
