Electron beams are a promising technology for treating a large amount of air pollutants with high energy for a fast reaction time. For these reasons, the electron beams have been employed to control NOx (NO and NO₂) and SO₂ generated from stationary emission sources. In recent years, NH₃ was commonly added in the electron beam process to achieve a high removal performance for NOx and SO₂. However, the development of economically efficient and effective additives is still required to overcome relatively low removal ability for NOx. In this study, various experimental parameters that affect the removal efficiency of NOx and SO₂ based on electron beam technology were investigated. To obtain an optimal removal efficiency, three different types of parameters such as additives, absorbed doses, and initial concentrations were evaluated. The average removal efficiency of 200 ppm NOx and SO₂ was 46.7% at an absorbed dose of 20 kGy when NH₄OH was used as an additive. However, the average removal efficiency (80.6%) of NOx and SO₂ increased additionally up to 33.9% when the NaOH additive was added in an electron beam process. The removal efficiency of NOx and SO₂ increased systematically with an increasing absorbed dose or decreasing initial concentration. Among the various experimental parameters, the type of additives was the most influential factor on the removal efficiency, especially for NOx, in an electron beam process.

电子束是一种有前途的技术，可用于以高能量处理大量空气污染物，并能快速反应。由于这些原因，已经采用电子束来控制从固定排放源产生的NOx（NO和NO ₂）和SO ₂。近年来，在电子束工艺中通常添加NH ₃以实现对NOx和SO ₂的高去除性能。然而，仍然需要开发经济有效的添加剂以克服相对较低的NO x去除能力。在这项研究中，影响NOx和SO ₂去除效率的各种实验参数基于电子束技术的研究。为了获得最佳的去除效率，对三种不同类型的参数（例如添加剂，吸收剂量和初始浓度）进行了评估。当使用NH ₄ OH作为添加剂时，在吸收剂量为20 kGy时，200 ppm NOx和SO ₂的平均去除效率为46.7％。但是，当在电子束工艺中添加NaOH添加剂时，NOx和SO ₂的平均去除效率（80.6％）进一步增加，最高达到33.9％。NOx和SO ₂的去除效率随着吸收剂量的增加或初始浓度的降低而系统地增加。在各种实验参数中，添加剂的类型是影响电子束处理过程中去除效率的最主要因素，尤其是对于NOx而言。
