| Abstract: | The planar membrane reactor configuration was explored for partial oxidation of methane (POM) to syngas. A supported membrane composed of yttria‐stabilized zirconia and La0.8Sr0.2Cr0.5Fe0.5O3‐δ was sealed to a stainless holder, and a Ni/Al2O3 catalyst bed was placed under the membrane plane with a small slit between them. This reactor configuration would facilitate the POM reaction via oxidation‐reforming mechanism: the oxidation reaction occurring at the membrane surface and the reforming reaction taking place in the catalyst bed. At 800°C and a methane feed rate of 32 mL min?1, the reactor attained methane throughput conversion over 90%, CO and H2 selectivity both over 95%, and an equivalent oxygen permeation rate 1.4 mL cm?2 min?1. The membrane and catalyst remained intact after the POM testing. The planar membrane reactor configuration explored in this study may lead to the development of a compact reactor for syngas production. © 2016 American Institute of Chemical Engineers AIChE J, 62: 2170–2176, 2016 |
