Abstract: The hydrogenation and dehydrogenation process is a common chemical reaction method, which involves the chemical reaction between oxides and hydrogen atoms in related compounds to remove or add hydrogen gas, thereby changing the internal composition of the compound. This article provides a detailed analysis of the process design flow for preparing zirconium-2 powder through hydrogenation and dehydrogenation, and comprehensively explores its applications and background. By exploring the safety of this process technology through steps such as hydrogenation, coarse crushing and fine crushing, dehydrogenation, secondary coarse crushing and fine crushing, passivation and separation, clarify its operating range, fully utilize the advantages of this process, greatly improve the preparation effect of the process to meet the needs of adjusting compound properties.

Key words: zirconium-2 powder process, passivation separation, hydrogenation and dehydrogenation preparation, safety
