摘要
氨作为富氢物质含氢的质量百分比是17.6%,常温常压下,气态的氨很容易转化为液体,液氨储能高,同样体积的液氨比液氢的高40%,而且便于储存和运输,并且在需要的时候可方便地热解到氢,是氢能的理想载体,作为富氢燃料,在以氢燃料电池为代表的氢经济中有很好的应用前景。氨作为燃料,燃烧值和辛烷值高,也可以直接作为发动机的燃料和燃料电池的燃料,氨是一种非碳基氢源,不含COx,可以为价廉高效的碱性燃料电池的推广作基础。
Ammonia contains 17. 6wt% hydrogen, which can be easily quelified at constant temprature and pressure. Ammonia contains 40% more energy than Hydrogen with the same volume. Ammonia is easily stored and trasported, and hydrogen is conveniently received by ammonia pyrolysis, so ammonia is an ideal carrier of hydrogen energy. As a hydrogen-rich fuel, ammonia has a good prospect in hydrogen economic with hydrogen fuel cell as a representive; as a fuel, ammonia with high combusting value and octane value can be used in engine and fuel cell. Particularly,ammonia with no COx will promote the application of the cheap and efficient alkaline fuel cell .
