常压微波等离子体微波功率对硫化氢分解效率的影响
Influence of microwave power on decomposition of hydrogen sulfide by atmospheric microwave plasma
摘要
Abstract
To remove a large amount of poisonous gas(H2S) produced by oil processing, the effect of microwave power on the decomposition efficiency of H2S was studied by atmospheric microwave plasma, in which the plasma was generated by the microwave with the carrier gas of Ar, CO2, and the mixture of Ar and CO2. The results show that the decomposition efficiency of H2S is improved by the increase of microwave power in a certain range of 400 W to 1 100 W; when the microwave power continues to increase, the decomposition efficiency is changed unobviously with the different carrier gas. It is also found that the decomposition efficiency of H2S decreases with the increase of power from 1 100～1 500 W when the carrier gas is pure argon, however, the decomposition efficiency keeps almost constant when CO2 is injected to the Ar. This phenomenon indicates that CO2, in some degree, is benefit to promote the decomposition of H2S. The decomposition rate of 98. 64% is obtained with H2S treatment of 1 300 W, CO2/Ar/H2S of 8/1/1, total flow of 1 000 mL/min. It is better to set the microwave power at 900 W to save energy.关键词
