Mesoporous Inorganic Membrane Reactor for Oxidative Coupling of Methane

Two-Dimensional Modeling of a Packed-Bed Membrane Reactor for the Oxidative Coupling of Methane

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.

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 ...

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...

CFD-simulation of membrane reactor for methane steam reforming

A membrane reactor is a reaction system that provides higher productivity and lower separation cost in chemical reaction processes. In this paper, packed bed catalytic membrane reactor with palladium membrane for methane steam reforming was analyzed both experimentally and numerically. The numerical model consists of a full set of partial differential equations derived from conservation of mass...
