Methane coupling by membrane reactor. Quarterly technical progress report, June 25, 1995--September 24, 1995

PDF Version Also Available for Download.

Description

The research focus, for the development of a radial flow catalytic membrane reactor for studying methane coupling, concentrated on understanding the effects of pore size, catalyst loading and catalyst distribution inside the membrane, on the hydrocarbon selectivity. The experimental results from the catalytic studies of oxidative coupling of methane in the radial flow membrane reactors are summarized in this report and the reactor performances of three radial flow reactors with pore sizes of 0.02 {mu}m are interpreted by the energy dispersive X-ray digital mapping (EDX) technique. A conventional fixed bed catalytic reactor was set up and run under the same ... continued below

Description

The research focus, for the development of a radial flow catalytic membrane reactor for studying methane coupling, concentrated on understanding the effects of pore size, catalyst loading and catalyst distribution inside the membrane, on the hydrocarbon selectivity. The experimental results from the catalytic studies of oxidative coupling of methane in the radial flow membrane reactors are summarized in this report and the reactor performances of three radial flow reactors with pore sizes of 0.02 {mu}m are interpreted by the energy dispersive X-ray digital mapping (EDX) technique. A conventional fixed bed catalytic reactor was set up and run under the same conditions as were used for the radial flow reactor studies. Two sources of samarium oxide catalysts were used in these experiments and their performances were compared in terms of C{sub 2} selectivity at same methane conversion. Compared to the monoclinic form of samarium oxide, the catalyst with cubic form was more active and selective for methane oxidative coupling. A general reactor model for oxidation reactions with distributed feed of oxygen and product removal strategies was proposed. Six types of feeding modes were analyzed and their feed distributions were optimized such that the desired product yields at the reactor outlet were maximized.
