High concentration benzene production in paper and painting industries is a restrictive problem in production line of companies. In this study, removal of high concentrated benzene produced in painting companies was investigated using a Plate Gliding Arc (PGA) reactor. Decomposition of methane and carbon dioxide as the most predominate byproducts of benzene decomposition was also studied using (PGA) reactor. The effect of several parameters such as input power, feed gas flow rate, type of carrier gas, and [CH/CO] flow ratio was studied by two series of experiments. The results show significant conversion (>70%) of high concentration benzene (74000ppm) without using any catalyst. Selectivity of CO and CO was 88% and 10% respectively showing complete oxidation of benzene. The maximum conversion of CH and CO reached 52% and 69%, respectively by using optimum ratio of 3:4. The main results of this study proved removal of high concentration benzene using a low-energy-density reactor. Furthermore, an optimum value for efficient conversion of methane and carbon dioxide was achieved and the energy density of the PGA reactor was evaluated, which shows a good promise for industrial applications.
造纸和涂装行业中高浓度苯的产生是企业生产线中的一个限制性问题。在本研究中，使用板式滑动弧（PGA）反应器对涂装企业产生的高浓度苯的去除进行了研究。还使用（PGA）反应器研究了作为苯分解最主要副产物的甲烷和二氧化碳的分解。通过两组实验研究了输入功率、进料气体流速、载气类型和[CH/CO]流量比等几个参数的影响。结果表明，在不使用任何催化剂的情况下，高浓度苯（74000ppm）的转化率显著（>70%）。CO和CO的选择性分别为88%和10%，表明苯完全氧化。通过使用3:4的最佳比例，CH和CO的最大转化率分别达到52%和69%。本研究的主要结果证明了使用低能量密度反应器去除高浓度苯。此外，实现了甲烷和二氧化碳高效转化的最佳值，并评估了PGA反应器的能量密度，这对工业应用具有良好的前景。
