The operation cycle of the catalyst used in conversion at lowtemperature is critical to the direct economic returns of the enterprises which produce synthetic ammonia.
中温变化催化剂运行的周期长短，是关系到合成氨生产企业直接经济效益的关键因素。

The process had the advantages of low reaction temperature, high conversion rate, high yield, recycle of solvent, and low waste disposal.
该工艺具有反应温度低、反应完全、转化率高、溶剂可回收利用、三废少的特点。
