Plasma assisted conversion of methane and carbon dioxide

甲烷和二氧化碳的等离子体辅助转化

基本信息

项目摘要

Several technologies including catalysis and plasma have already been proposed to improve the process involving conversion of methane and carbon dioxide into useful chemical intermediates. The conversions in dielectric-barrier discharges (DBD) or in gliding discharges (GD) were influenced significantly by discharge power, applied voltage, and catalysts. The detailed experience of the Warswava group in this field of non-thermal plasma applications including catalysts will be combined with a novel plasma source developed in Braunschweig. That source consists of electrodes (and distances between the electrodes) in the 10μm range allowing the generation and steering of plasmas at different discharge properties compared to DBD and GD. In addition, a sequential arrangement of these plasma sources is possible which allows a significant improvement in both efficiency and selectivity. The operating pressure can be as high as that of ambient air.Preliminary results obtained in Braunschweig show that many of the main products, C2H2, C2H4, C2H6, CH3COOH, CH3OH, HCHO, CO, H2, can be generated with efficiencies much better than10%. Since a catalyst placed in the discharges of the plasma affects the product distributions significantly, an even higher product yield than already observed can be expected. The mechanisms of product formation are still not understood and detailed analytics will be used, including on-line mass spectrometry, GC, laser induced fluorescence, FT-IR, optical emission spectroscopy (OES), and Cavity-Ring-Down (CRD) spectroscopy. The merits and drawbacks of either plasma technique will be assessed. The suitable technique or a combination of both will be identified and optimized. The CO2 reforming of methane using plasma-catalytic coupled process may be a source of desired products including ethylene and methanol, by one-stage operation. The selected process will be simple, exhibits low carbon production, and is not as energy intensive as Fischer-Tropsch. Some products (CH3COOH, CH3OH, HCHO) might even be found as a liquid.
已经提出了包括催化和等离子体在内的几种技术来改进将甲烷和二氧化碳转化为有用的化学中间体的过程。介质阻挡放电(DBD)和滑动放电(GD)的转化受放电功率、外加电压和催化剂的显著影响。华沙小组在包括催化剂在内的非热等离子体应用领域的详细经验将与在布伦瑞克开发的新型等离子体源相结合。该源由10μm范围内的电极(以及电极之间的距离)组成,与DBD和GD相比,可以在不同的放电特性下产生和控制等离子体。此外,这些等离子体源的顺序排列是可能的,这可以显著提高效率和选择性。操作压力可与环境空气压力一样高。在布伦瑞克获得的初步结果表明,许多主要产物,C2H2、C2H4、C2H6、CH3COOH、CH3OH、HCHO、CO、H2的生成效率都远高于10%。由于放置在等离子体放电中的催化剂会显著影响产物分布,因此可以预期比已经观察到的更高的产物收率。产物形成的机制仍然不清楚,详细的分析将被使用,包括在线质谱,GC,激光诱导荧光,FT-IR,光学发射光谱(OES)和腔衰荡(CRD)光谱。我们将评估这两种等离子体技术的优缺点。将确定并优化合适的技术或两者的组合。利用等离子体-催化偶联工艺对甲烷进行CO2重整,可通过一级操作获得乙烯和甲醇等所需产物。所选择的过程将是简单的,展示低碳生产,并且不像费托那样能源密集型。有些产物(CH3COOH, CH3OH, HCHO)甚至可能是液态的。
