柴油发动机尾气中存在大量颗粒物，它易被人体吸入，对人的身体健康造成极大危害。其主要成分——碳烟及可溶性有机成分（SOF）等，可通过氧化燃烧的方法除去。本文从柴油机尾气颗粒物的治理出发，介绍了传统的颗粒物后处理技术，包括颗粒捕集器结合再生、微粒催化氧化转化（DOC）、静电捕集等技术。主要介绍了近年所发展起来的低温等离子体（NTP）辅助去除含碳固态混合物（PM）技术，包括等离子体反应器中的化学反应，常见的低温等离子体反应器结构及等离子体产生的放电类型。此外，根据等离子体反应器的安装位置不同，还介绍了两种不同的等离子体PM处理方法——直接等离子体方法和间接（远程）等离子体方法，后者可避免高温对等离子体过程的不利影响。总结了等离子体技术的应用特点，提出对等离子体辅助PM去除过程的研究可着眼等离子体技术本身，研究各种对气体放电产生影响的因素，为等离子体反应器的开发和应用提供参考。

The particulate matter in diesel engine exhaust can easily get inhaled and do great harm to human health. Incineration of particulate matter from diesel exhaust can be realized simply by oxidation,yet it mainly consists of carbon soot and SOF. The aftertreatment techniques for PM, including diesel particulate filters ( DPFs ) coupled with regeneration , diesel oxidant catalyst (DOC),and electrostatic capture are reviewed. The non-thermal plasma technique is introduced. The common chemical reactions in plasma reactors are presented. Different types of discharge in gas are also discussed. Direct and indirect plasma method based on different locations of plasma equipment are presented. The latter one helps avoid bad effects on plasma process caused by high temperature. The traditional methods for soot inciberation are rather mature in comparison with the plasma method. So more researches on the plasma process are suggested,so as to provide reference for the development and application of plasma reactors.
