| Abstract Scope |
As decarbonization efforts intensify, green hydrogen has emerged as a critical component for various industrial applications, serving both as a reducing agent and a fuel.
Despite its potential, there is limited comparative research on the impact of hydrogen on refractory lining materials used in high-temperature processes, such as the direct reduction of iron (DRI) and reheating furnaces.
This study addresses this gap by conducting corrosion tests on a selection of dense and lightweight refractories exposed to hydrogen. The primary focus is on the microscopical and chemical analyses of the refractory materials post-exposure, which provide insights into the reduction behavior of different phases. The findings contribute to a better understanding of refractory lifetime and performance in highly reducing atmospheres, aiding in the prediction and enhancement of refractory durability in hydrogen-exposed environments. |
