摘　　要：对甲烷(CH4)与氪(Kr)共吸附条件下的脱附行为开展了实验研究。研究了脱附温度、升温速率和吹扫流量对CH4和Kr脱附行为的影响。实验结果表明:CH4和Kr具有相似的脱附行为,在不同脱附温度、升温速率和吹扫流量下,CH4和Kr脱附曲线的峰形和峰位基本相同;CH4和Kr脱附曲线的出峰时间随脱附温度、升温速率和瞬时吹扫流量的增加而缩短,而CH4和Kr的脱附曲线随累积吹扫流量的变化趋势在不同瞬时吹扫流量下基本相同。The desorption behaviors of CH4 and Kr under co-adsorption were studied.The effects of desorption temperature,heating rate and purge gas flow rate on the desorption behaviors of CH4 and Kr were investigated.The results show that CH4 and Kr have similar desorption behaviors.The peak shapes and peak positions of CH4 and Kr desorption curves are basically same at different desorption temperature,heating rate and purge gas flow rate.The peak times of CH4 and Kr desorption curves are shortened with the increase of desorption temperature,heating rate and instantaneous purge gas flow rate,while the desorption curves of CH4 and Kr are similar with the cumulative purge gas flow rate.
