摘要
利用甲烷的强吸收振动带v3,采用吸收光谱法通过测量3391nm He-Ne激光穿过等离子体反应管的透射光强来考察甲烷完全裂解时间随放电电流和气压的变化规律。实验结果表明:对实验所用的封离系统,在直流和高频(33KHz)放电条件下,所得的甲烷裂解率分别为96%和98%。甲烷完全裂解的时间随气压的增加而增加,随放电电流的增大而减小;裂解效率直流放电比高频放电的高。
Using sensitive absorption spectral band v3 of methane, the changes which methane completes decomposition time with discharge current and pressure were inspected through measuring the transmission rate of 3391 nm He - Ne laser crossing the plasma reactor by laser absorption spectrum method. To used sealed system, the decomposition rates of methane obtained in DC and 33KHz high - frequency discharge are 96% and 98% respectively The time methane complete decomposition needed increases with the pressure increasing, and short with the discharge current increasing; the methane decomposition efficiency in DC discharge is higher than in high- frequency discharge.
