- 摘要:
- 为探究常温下初始氢气体积分数、氧气流速和催化剂质量对氢-氧催化复合反应温度以及消氢效果的影响，利用铂/碳（Pt/C）催化剂，在自行设计的圆柱形容器中开展氢-氧复合催化消氢实验，基于热电偶和氢气浓度传感器采集的温度及氢气体积分数探究发展规律。研究结果表明：温度峰分布模式受反应参数的影响较大；当氢气体积分数小于当量比时，氢气转化率在本文研究条件下均达到100%；反应温度的变化主要由氢气体积分数主导，当氢气体积分数小于当量比时，温度峰值随氢气体积分数增加而增加；氧气流速对温度传递方向影响有限，但其过高会增加系统的散热能力，从而影响催化剂的热积聚。研究结果可为密闭环境中的氢气消除设计提供参考依据。
- Abstract:
- In order to investigate the influence of initial hydrogen volume fraction,oxygen flow rate and catalyst quality on the temperature of the hydrogen-oxygen catalytic recombination reaction and the effect of hydrogen elimination at room temperature,the hydrogen-oxygen composite catalytic hydrogen elimination experiments were carried out in a self-designed cylindrical vessel using platinum/carbon (Pt/C) catalysts,and the development pattern was investigated on the basis of the temperatures and hydrogen volume fraction collected by the thermocouples and hydrogen concentration sensors.The results show that the distribution pattern of temperaturepeak is greatly affected by the reaction parameters.When the hydrogen volume fraction is less than the equivalent ratio,the hydrogen conversion rate reaches 100% under the conditions in this study.The change of reaction temperature is mainly dominated by the hydrogen volume fraction,and when the hydrogen volume fraction is less than the equivalent ratio,the temperature peak increases with the increase of hydrogen volume fraction.The oxygen flow rate has a limited effect on the direction of temperature transfer,but its excessively high level increases the heat dissipation capacity of the system,thus affecting the heat accumulation of catalyst.The research results can provide reference basis for the design of hydrogen elimination in confined environments.
