Abstract

As ammonia does not emit greenhouse gases when burned, it is considered a fuel instead of fossil fuels. However, there are few reports on the corrosion behavior of materials when ammonia is used as fuel. Therefore, this study measured the hydrogen produced by the reaction between ammonia and iron using a hydrogen sensor containing a proton conductor. As a result, the amount of hydrogen produced by the decomposition of ammonia was small at low temperatures but increased at high temperatures. Also, when the ammonia content was low, oxidation of iron occurred preferentially. This way, the relationship between the amount of hydrogen generated and corrosion behavior could be clarified.

使用氢气和氧气传感器评估纯铁在氨气环境中的环境行为
由于氨在燃烧时不会排放温室气体,因此被认为是一种替代化石燃料的燃料。然而,有关使用氨作为燃料时材料腐蚀行为的报道却很少。因此,本研究使用含有质子导体的氢传感器测量氨和铁反应产生的氢。结果发现,氨分解产生的氢气量在低温时很少,但在高温时却有所增加。此外,当氨含量较低时,铁的氧化作用优先发生。这样,产生的氢量与腐蚀行为之间的关系就可以得到澄清。

期刊介绍: Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
