常压非平衡等离子体合成NH_3

Synthesis of NH 3 by Non Equilibrium Plasma under Normal Pressure

８０年代以来，不少科学家探讨了在低压下，用射频（１３．５６ＭＨｚ）或微波（２４５０ＭＨｚ）激发的辉光放电，将Ｎ２、Ｈ２电离、分解成Ｎ·、Ｈ·、ＮＨｘ等多种自由基，在固体表面的催化或催化剂的作用下，合成ＮＨ３［１～３］．但由于低压下稀薄气体的合成，只能...

A violent streamer discharge produced by ultra strong narrow pulse electric field in the whole reactor makes N 2 and H 2 ionize and dissociate to transform a large number of free atoms, ions and radicals forming a non equilibrium plasma at normal pressure. The concentration of NH 3 gas thus synthesized could reach 4884 μL/L.
