在过去的几年里，我们的工作集中在确定固态金属氧化物的晶体学和热力学性质之间的相互关系，以及它们如何与同时实现高离子和高电子导电性相关。这项工作导致了一种新型的氧阴离子和电子导电褐磨矿衍生膜材料，这种膜材料已被纳入催化膜反应器（CMRs）中，以实现天然气以实际速率自发转化为合成气，并具有长时间的完全材料稳定性。Eltron Research正在开发的CMR技术，促进了氧气从大气到所需反应部位的独家调解-在这种情况下，天然气部分氧化为合成气。由于这种CMR工艺是放热的，不需要单独的制氧装置，因此与现有技术相比，可以显著降低合成气生产成本。此外，由于该膜仅介导氧气，排除了大气中的氮，因此可以消除nox的排放。
Over the last several years our work has focused upon determining the interrelationship between crystallographic and thermodynamic properties of solid state metal oxides and how they relate to achieving simultaneous high ionic and electronic conductivity. This work has led to a new class of oxygen anion and electron conducting brownmillerite derived membrane materials which have been incorporated into catalytic membrane reactors (CMRs) for achieving the spontaneous conversion of natural gas to synthesis gas at practical rates with complete materials stability for extended periods. CMR technology under development at Eltron Research, facilitates the exclusive mediation of oxygen from the atmosphere to a desired reaction site — in this case natural gas partial oxidation to synthesis gas. Because this CMR process is exothermic and eliminates the need for a separate oxygen plant, a significant reduction in synthesis gas production costs may be realized compared to currently available technology. Additionally, NOxemissions are eliminated since the membrane only mediates oxygen and excludes atmospheric nitrogen.
