常压微波等离子射流脱碳处理有机工业废气

Decarbonization disposal of organic industrial exhaust gas by atmospheric pressure microwave plasma jet

在自行设计的常压微波等离子体射流装置上进行了丙酮模拟有机工业废气的脱碳实验,得到了纳米碳粉.利用Raman光谱、XRD、SEM、TEM和EDAX对制得的碳粉的结构和形貌进行了分析.体积分数62.5%的有机废气在等离子体射流的作用下得到的固态碳粉以微晶石墨结构为主,含有少量的微晶金刚石结构.TEM分析表明石墨晶体为颗粒状和层状结构.该技术可用于有机废气的脱碳处理和纳米碳粉的回收利用.

Decarbonization of the organic industrial exhaust gas simulated by acetone had been accomplished on a self-designed atmospheric pressure plasma jet apparatus and a nanometer carbon powder had been obtained. The structure of the carbon powder had been analysized using laser Raman spectroscopy, XRD, SEM, TEM and EDAX. The products obtained from the concentration 62. 5% organic exhaust gas by plasma jet mainly contain minuteness graphite and little micro-crystalline diamond. TEM analysis shows that the graphites are particle or layer structure. This technology has potential application in the decarbonization treatment of organic exhaust gas and the reclaiming utilization of the nanometer carbon powder.
