Abstract

The energy utilization and kinetic characteristics in pulsed bipolar plasma catalysis of organic reactants were investigated. A kinetic theoretical formula was established for depicting the plasma dissociation and synergistic catalysis. The synergy factors of C₅ − C₁₀ n-alkanes were independent of the number of secondary hydrogens, but for (CH₃)_m-benzenes (m = 0 − 3), as the number of methyl groups increased, the synergy factors slightly increased. The rate of increase in energy utilization due to the synergy effect was inversely proportional to the reactivity of reactants. Some energy from plasma discharge was wasted at low conversion until the catalytic activity began to play a role. The energy utilization increased considerably once the catalytic effect was activated. However, when the reactant was close to its complete oxidation, the plasma dissociation and catalysis reactions competed with each other, leading to wastage of some of the energy. These phenomena were more remarkable for the alkanes than for the aromatics.

等离子体催化协同效应与反应物的结构键强度和感应效应相关的能量利用和动力学特性

摘要

研究了脉冲双极等离子体催化有机反应物的能量利用和动力学特性。建立了动力学理论公式来描述等离子体的离解和协同催化作用。C的协同因子₅  - Visual C ₁₀正构烷烃是独立的次级的氢的数目的，但对于（CH ₃）_米-苯（米 = 0-3），随着甲基数量的增加，协同因子略有增加。由于协同作用，能量利用的增加速率与反应物的反应性成反比。等离子体放电产生的一些能量以低转化率被浪费掉，直到催化活性开始发挥作用。一旦催化作用被激活，能量利用就显着增加。然而，当反应物接近其完全氧化时，等离子体的解离和催化反应相互竞争，导致一些能量的浪费。对于烷烃而言，这些现象比对芳烃而言更为显着。
