We describe a three-step bromine-mediated process for oxidative coupling of methane using O2 as oxidant. In the first step, a supported metal bromide solid is treated with O2 to generate Br2 and supported metal oxide. The Br2 thus formed reacts with excess CH4, giving a mixture of CH4, bromomethanes, and HBr. This mixture is passed over a CaO/zeolite composite which condenses bromocarbons with ...
The oxidative coupling of methane (OCM) to C2 hydrocarbons (C2H4 and C2H6) has aroused worldwide interest over the past decade due rise vast new shale gas resources. However, obtaining higher selectivity can be very challenging in a typical OCM process presence easily oxidized products such as C2H4 C2H6. Regarding this, different types catalysts have been studied achieve desirable yields. In th...
Oxidative coupling of methane (OCM) is an exothermic reaction that results in the temperature rise towards latter part reactor. This study reports consequence OCM product distribution after O 2 depletion at high temperatures.
Kinetic behaviour of three samples of samarium oxide (cubic (Sm-1 ), monoclinic (Sm-3) and mixed cubic-monoclinic (Sm 2) ) were studied in the oxidative coupling of methane using a gradientless flow circulation system. The specific rate of C2product formation differed by a factor of 6-8 for Sm-1 and Sm-3. The specific activity for CO formation did not depend upon the crystal structure of samari...
The oxidative coupling of methane (OCM) was investigated using a catalyst with core@shell structure or physical mixture comprised MgO and SiC Fe 3 O 4 , which thermally activated via conventional resistive heating microwave heating.
