研究了室温下连续流动表面放电等离子体脱除气体中异戊醛的性能。通过监测不同运行参数（如比能、空气流量和入口浓度）下的去除效率和矿化度，系统地评估了放大反应器去除污染物的可行性。结果表明，流量的增加导致去除能力的提高。例如，当流量增加两倍时，去除能力在0.6到1.1gh（-1）之间变化。此外，随着比能的增加，去除能力和矿化能力都得到了提高。此外，还对表面放电等离子体系统进行了实验室和中试规模的比较。提出了一种表面放电等离子体系统的放大方法。在这种情况下，去除能力进行了比较不同的连续反应器：两个反应器在实验室规模（平面和圆柱形反应器），和试点单位。结果表明，等离子体反应器的放大去除污染物是可行的。(C)2016化学工程师学会。Elsevier B.

This work investigated the performance of Isovaleraldehyde (3-methylbutanal) removal from gas streams using continuous flow surface discharge plasma at room temperature. The feasibility of pollutant removal using up-scaled reactor was systematically assessed by monitoring removal efficiency and mineralization at different operational parameters, such as specific energy, air flow rate and inlet concentration. Results show that increasing flow rate lead to improve the removal capacity. For example, when flow rate extends two times, the removal capacity varies from 0.6 to 1.1 gh(-1). Moreover, when specific energy increased, both removal capacity and mineralization were enhanced. Additionally, a comparison between laboratory and pilot scales using surface discharge plasma system was carried out. A methodology of scaling up the.surface discharge plasma system was proposed. In this context, removal capacities were compared for different continuous reactors: two reactors at laboratory scale (planar and cylindrical reactor), and pilot unit. The results suggest that the plasma reactor scale-up for pollutant removal can be feasible. (C) 2016 The Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.
