Non-oxidative methane coupling to C2hydrocarbons in a microwave plasma reactor

Miniplant-Scale Analysis of Oxidative Coupling of Methane Process

For more than three decades, Oxidative Coupling of Methane (OCM) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. Developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...

Catalytic and Non-catalytic Conversion of Methane to C2 Hydrocarbons in a Low Temperature Plasma

The direct conversion of methane to C2 hydrocarbons, in a quartz tube reactor enforced by a DC corona discharge, was investigated at atmospheric pressure. The process was carried out in the presence of metal oxide catalysts of Mn/W/SiO2, Mn/W/SiO2 (tetraethyl orthosilicate, TEOS), and Mn/W/CNT (supported on carbon nanotubes). The total yield to C2 hydrocarbons in the presence of metal oxide cat...

Oxidative coupling of methane in a mixed-conducting perovskite membrane reactor

Ionic-electronic mixed-conducting perovskite-type oxide Lao6Sro.4Coo.sFeo203 was applied as a dense membrane for oxygen supply in a reactor for methane coupling. The oxygen permeation properties were studied in the po,-range of 10-3-1 bar at 1073-1273 K, using helium as a sweeping gas at the permeate side of the membrane. The oxygen semi-permeability has a value close to 1 mmol m ~ s ~ at 1173 ...

Real time chemical imaging of a working catalytic membrane reactor during oxidative coupling of methane.

We report the results from an operando XRD-CT study of a working catalytic membrane reactor for the oxidative coupling of methane. These results reveal the importance of the evolving solid state chemistry during catalytic reaction, particularly the chemical interaction between the catalyst and the oxygen transport membrane.
