摘要

等离子体诱导的二氧化碳加氢过程已受到广泛关注,但相关的等离子体化学却未得到深入探讨。本文研究了在介质势垒放电反应器中二氧化碳加氢的电子诱导效应和热化学效应。CO2/H2、CO2/H2/N2、CO2/H2/Ar 和 CO2/H2/He 混合物的放电模式转变温度分别为 623、623、600 和 600 K。二氧化碳的转化受电子诱导反应控制,对放电模式和电子密度敏感,但对电子能量不敏感。相比之下,产物的形成受热诱导化学反应的控制。这些结果有助于更好地理解等离子体诱导的二氧化碳氢化。

Mechanism of plasma chemistry in CO2 hydrogenation using a dielectric barrier discharge reactor
Plasma‐induced CO2 hydrogenation process has received much attention, while the related plasma chemistry has not been profoundly explored. Herein, electron‐induced and thermochemical effects on CO2 hydrogenation in a dielectric barrier discharge reactor were investigated. The temperatures for the discharge pattern transition for CO2/H2, CO2/H2/N2, CO2/H2/Ar, and CO2/H2/He mixtures were 623, 623, 600, and 600 K, respectively. CO2 conversion was controlled by electron‐induced reactions and was sensitive to discharge pattern and electron density but not electron energy. In contrast, product formation was governed by the thermo‐induced chemistry. These results are useful for a better understanding of plasma‐induced CO2 hydrogenation.
