一种提升制备羰基镍原料活性的方法
摘要：
一种提升羰基镍原料活性的方法，涉及一种将镍原料进行活化处理，提升其羰化率的改进方法。其特征特在于其方法是将镍原料在还原炉内与通入还原炉的含有SO2的氢气进行反应，对羰基镍原料活性进行活化。本发明的一种提升羰基镍原料活性方法，操作简便，效果明显，易于实现。经检测，镍原料中硫含量从0.14-0.43%增加至1.9-2.42%，在羰化合成过程中反应速率明显改变，最终提高了镍原料羰化率。
摘要（英）：

The invention provides a method for enhancing activity of a nickel carbonyl raw material, and relates to an improved method for enhancing carbonylation rate by performing activating treatment on a nickel raw material. The method is characterized by comprising the following step: introducing SO2-containing hydrogen into a reducing furnace to react with the nickel raw material in the reducing furnace, thereby enhancing the activity of the nickel carbonyl raw material. The method for enhancing activity of the nickel carbonyl raw material is simple to operate and easy to implement, and has obvious effect. The detection proves that the sulfur content in the nickel raw material is increased from 0.14-0.43% to 1.9-2.42%, and the reaction rate is obviously changed in the carbonylation synthesis process, thereby finally enhancing the carbonylation rate of the nickel raw material.
