MoO3-MoO2氢还原过程中的速率控制

摘要

MoO3-MoO2反应过程属放热反应,反应过程受反应产物MoO2的自催化.根据该反应过程中氢气流量、氢气露点、不同温度梯度与反应速率的关系,通过合理的工艺优化,有效地控制反应速率、充分利用反应过程中放出的热量来维持后续反应的进行,降低MoO2的板结与团聚,稳定了MoO2产品质量.%The M0O3-M0O2 reaction process is an exothermic reaction, whose reaction process is auto-catalytized byrnMoO2. This paper studies the relationship of reaction rate, hydrogen flow rate during reaction process, hydrogen dewrnpoint, and different temperature gradient. The product quality of MoO2 is improved by reducing the compaction andrncluster of MoO2 out of optimizing hydrogen reduction process, which makes full use of heat generated by reactionrnprocess to maintain the following reaction and effectively controls the reaction rate.
