Abstract

A novel plasma reactor is being investigated for green NOx production, crucial for nitrate‐based fertilizer manufacturing. Various parameters, including air flow rates, gas ratios, ozone, and catalyst effects are explored for NO → NO2 conversion. NOx concentrations reach ~0.6 vol%, with a total production of ~9.7 gr/h and energy cost of ~3.0 mJ/mol, notably favorable for atmospheric gliding arc plasma. Selectivity (~75%) towards NO2 is achieved with ozone addition or catalytic treatment, pivotal for nitrate fertilizer and HNO3 production.

利用新型滑行弧等离子体反应器进行可持续固氮以生产氮肥

目前正在研究一种新型等离子体反应器，用于氮氧化物的绿色生产，这对硝基化肥的生产至关重要。研究了各种参数，包括空气流速、气体比例、臭氧和催化剂对 NO → NO2 转化的影响。氮氧化物浓度达到约 0.6 vol%，总产量约为 9.7 gr/h，能耗约为 3.0 mJ/mol，明显有利于大气滑行弧等离子体。通过添加臭氧或催化处理，可实现对二氧化氮的选择性（约 75%），这对硝酸盐肥料和 HNO3 的生产至关重要。
