There are four major steps in ammonia synthesis. 氨的合成主要經(jīng)過(guò)四道工序。
Ruthenium catalysts are considered as the second generation catlysts for ammonia synthesis following iron catalysts. 釕基催化劑被稱(chēng)為繼鐵基催化劑之后第二代氨合成催化劑。
The results are fundamental to the research and preparation of lowtemperature, hith activity and low cost cobalt-iron ammonia synthesis catalyst. 較深入地探討了鈷含量和鐵比變化對催化活性影響的規律及其原因，為制備低溫高活性和較低成本的含鈷熔鐵氨合成催化劑提供了理論基礎。
