研究了数种烃包括液态苯和甲苯以及气态的甲烷、乙烯及乙炔在氮热等离子体中的热解行为。结果发现，所有烃化合物在氮等离子体中均发生了强烈的分解反应，生成大量炭黑和气体。气体产物中的主要成分是氢、乙炔和丙炔腈，在液态烃苯和甲苯的热解产物中还含有甲烷及乙烯等小分子烃。乙炔的浓度与丙炔腈的含量有关。丙炔腈的含量高时，乙炔的浓度低，反之亦然。所制得的炭黑颗粒细小，粒度分布范围较窄，具有较强的吸附性能，其碘值为１４０～１８０ｍｇ／ｇ。用红外光谱研究了炭黑的表面结构，发现此类炭黑中存在芳香Ｃ－Ｃ键及大量氮基官能团，如＝ＮＨ、－ＣＮ等。
The pyrolysis behavior of several kinds of hydrocarbons including liquid benzene and toluene as well as gaseous methane, ethylene and acetylene in nitrogen thermal plasma was investigated. As a result, it was found that all hydrocarbon compounds undergo a strong decomposition reaction in the nitrogen plasma, generating a large amount of carbon black and gas. The main components of the gas product are hydrogen, acetylene and propiolein. The pyrolysis products of liquid hydrocarbon benzene and toluene also contain small molecule hydrocarbons such as methane and ethylene. The concentration of acetylene is related to the content of propiolene. When the content of the acetylene nitrile is high, the acetylene concentration is low, and vice versa. The obtained carbon black particles are small, the particle size distribution is narrow, and has strong adsorption performance, and the iodine value is 140-180 mg / g. The surface structure of the carbon black has been studied by infrared spectroscopy. It has been found that there are aromatic C-C bonds and a large number of nitrogen-based functional groups in such carbon blacks, such as = NH, -CN and so on.
