高流速下钯上氢氘的排代研究

DISPLACEMENT OF HYDROGEN-DEUTERIUM AT HIGH FLOW RATE IN PALLADIUM PARTICLE BED

在钯氘化物上进行了高流速下氢氘的排代实验。结果表明,氘的排代效率随排代时间的增大而增加;与低压、低流速相比,高流速下排代压力的增加部分弥补了流速增大对氢氘交换速率的影响,因此仍可以得到较高的氘回收率。

The displacement behavior of hydrogendeuterium at the high flow rate has been studied. The results show that displacement efficiency of deuterium decreases as displacement time decreases.Compared with the effects at low flow rate,high displacement recovery ratio of deuterium still can be attained at high flow rate becaue higher displacement pressure that increases the collision frequency partly compensates the loss of exchange caused by an increase in flow rate.
