低温等离子体催化技术推广方面的难点问题

Difficult issues for popularization of non-thermal plasma catalytic technology

低温等离子体催化技术是近年来兴起的一种治理废气的可行方法,与传统方法和工艺相比,具有投资和运行费用较低、处理效率较高、处理时间较短和易于控制等优点。研究表明,利用等离子体技术处理大气污染的应用前景广阔。但低温等离子体技术反应器的选择、匹配和优化、相关催化剂的选择以及与反应器的结合、反应机理等方面还需要进一步深入研究。低温等离子体效率低、能耗高、目标产物选择性低,但加入催化剂可降低能耗,减少二次污染,提高产物选择性,两者取长补短,优势互补。不断改进反应器并提高反应器的能量效率,提升催化剂的稳定性和契合度以及对反应机理的深入研究是今后的发展方向。

Non-thermal plasma catalytic technology is a way to reduce exhaust gas in recent years. Compared with the traditional method and technology, it has the advantages of low cost in investment and operation, high energy efficiency, short processing time and easy control. Numerous studies at home and abroad showed that the treatment of air pollution with plasma technology had broad growth space. But the selection, matching and optimization of the reactor, the choice of the catalysts and their combination with the reactor, and the reaction mechanisms needed to be further researched. Non-thermal plasma catalytic technology had the disadvantages of low efficiency, high energy consumption and low selectivity to target products, but the addition of the catalysts could reduce energy consumption, decrease secondary pollution and enhance the selectivity to the products. To improve the reactors and their energy efficiency, enhance the stability of the catalysts and further research on the reaction mechanism are the development directions in the future.
