粉体比表面积对金属氢化物吸氢动力学的影响
Influence of Specific Surface Area of Powder on Hydrogen Desorption Kinetics for Metal Hydrides
摘要：
以金属氢化物粉末为例，用粉末比表面模型再现了金属氢化物粉末脱附动力学的观测结果。以湿球磨氢化镁为例，对氢脱附过程的容量测量进行了评价，并可普遍应用于任何金属氢化物。模型的精确解再现了脱附过程的实验曲线形状，与实验数据吻合较好。
英文摘要：
The observable results for desorption kinetics by powder of metal hydride on the example of mangesium hydride are reproduced with the model formulated in terms of specific surface of powder. A volumetric measurement of hydrogen desorption process is evaluated on an example of wet ball milled magnesium hydride, and can be applied generally for any metal hydride. The exact solution of the model reproduces the shape of experimental curves for desorption process providing a satisfying agreement with experimental data.
