Method for low-temperature hydrogenation refining of carbonate through mechanical force chemical pretreatment induction
The invention discloses a method for low-temperature hydrogenation refining of carbonate through mechanical force chemical pretreatment induction. The method specifically comprises the following steps: under the air condition of normal temperature and normal pressure, loading carbonate powder and grinding balls into a ball milling tank for ball milling, carrying out mechanical force chemical treatment for 2-16 hours to obtain completely non-crystallized carbonate, then carrying out thermal decomposition on the treated carbonate in a pure hydrogen atmosphere at 450-550 DEG C, and simultaneously preparing metal oxide and synthesis gas without CO2. According to the present invention, the long-range ordered crystal structure of carbonate is subjected to non-crystallization and in-situ modulation through the mechanochemical method, such that the carbonate hydrogenation reaction energy barrier can be easily reduced, the autocatalytic reaction efficiency can be easily improved, the reaction temperature can be easily reduced, the reaction time can be easily shortened, the complete inhibition of the CO2 generation at the low temperature can be achieved, and the CO2 emission in the process can be effectively reduced; meanwhile, high-purity synthesis gas without CO2 and a high-purity metal oxide product are obtained.
本发明公开了一种机械力化学预处理诱导碳酸盐低温加氢炼制的方法。所述方法的具体操作为：在常温常压空气条件下，将碳酸盐粉末与磨球装入球磨罐中球磨，通过机械力化学处理2‑16h后得到完全非晶化的碳酸盐，然后将处理后的碳酸盐在纯氢气氛中450‑550℃热分解，同时制备得到金属氧化物和不含有CO2的合成气。本发明通过机械力化学法对碳酸盐长程有序的晶体结构进行非晶化和原位调制，有利于降低碳酸盐加氢反应能垒，提高自催化反应效率，降低反应温度和所需时间，实现在低温下CO2生成的完全抑制，有效减少过程CO2排放，同时得到不含CO2的高纯合成气和高纯度金属氧化物产品。
