摘要

摘要: 利用电感耦合等离子体发射光谱、红外光谱分析和X射线衍射对不同固体颗粒物样品的特性进行了研究。结果表明,生物油中的固体颗粒物主要由焦炭颗粒、灰分和少量高分子有机物组成,其中,灰分主要包括多种金属元素和一定量SiO₂,有机物主要是具有木质素结构的低聚物。不同热解工艺的固体颗粒物样品特性也不同。循环流化床工艺制取的生物油中固体颗粒物含量较高。此外,固体颗粒物样品中的金属元素含量受到热解原料种类的影响。

Abstract: The quality of bio-oil is affected by solid particles. X-Ray Diffraction, Fourier Transform Infrared Spectroscopy and Inductively Coupled Plasma were used to investigate features of the particles. The results show that the content of particles varies with pyrolysis technology, and there are more particles in bio-oil obtained from circulating fluidized bed. The particles mainly consist of char, ash and a small amount of organic polymer. The major components of the ash are metal elements and SiO₂, while of the polymer is oligomer with lignin structure. The content of metal elements is influenced by the characteristics of raw material for pyrolysis.
