为探索CO_2气体在低温等离子体中的分解规律,开展了近室温条件下,射频等离子体中CO_2及CO_2-H_2混合气体的电离分解行为研究。反应产物通过差分四极质谱进行在线分析,并通过发射光谱对等离子体状态进行诊断。研究结果表明,在射频电场作用下二氧化碳气体迅速电离并部分分解为一氧化碳和氧气,随着射频功率升高CO_2分解率提高,而能量效率降低。氢气的加入可以显著降低CO_2分解达到平衡所需的时间,随着H_2含量的增加,二氧化碳的分解率先降低后升高,H_2的电离状态与对CO_2分解氧的消耗是导致CO_2分解率V字形变化的主要原因。

A key problem in CO_2 conversion by thermal plasma is suppressing the inverse reactions,CO?+?O?→?CO_2 and CO?+?0.5O_2?→?CO_2, to simultaneously obtain high CO yield and energy efficiency. This can be done by quickly quenching the decomposed gas or rapidly taking away free oxygen from decomposed gas. In this paper, experiments of CO_2 conversion by thermal plasma with carbon as a reducing agent are presented. Carbon quickly devoured free oxygen in thermal plasma decomposed gas, and not only is the inverse reaction completely suppressed, but the discharge energy to form oxygen atoms, oxygen molecular, and thermal energy is also reused.A CO_2 conversion rate of 67%–94% and the corresponding electric energy efficiency of about 70% are achieved, both are much higher than that seen so far by other plasma implementations.
