金属铋对铝基水反应材料水解性能的影响
Effect of Bismuth on Hydrolysis Properties of Aluminum-based Hydro-reactive Metal Materials
摘要
Abstract
The Al-Bi composites were prepared by high-energy ball milling method,and the effect of bismuth content on the conversion rate of hydro-reactive materials was studied.The effects of Al/water mass ratio and the initial reaction water temperature on the hydrolysis performance of Al-based hydro-reactive active materials were studied.The results show that bismuth content increases from 0 to 10 ％,hydrogen conversion of the composites increases from 5.4 ％ to 71.2 ％ first and then decreases to 62.4％,in which,the optimum mass fraction of bismuth is 5 ％.With the change of Al/water mass ratio from 1 ∶40 to 1 ∶ 100,the conversion of the composites is less affected,but the effect on the reaction rate is obvious.The hydrogen production rate is the highest of 114mL/(min · g) when mass ratio of Al/water is 1 ∶ 60.The hydrogen generation rate and conversion yield of the composites increases with the incurease of the initial temperature of seawater,and when the initial temperature of seawater increases from 20℃ to 80℃,the hydrogen conversion yield increases by 29.8 ％.关键词
