| 摘 要： | 生物质热解焦油的产生不仅降低了热解效率,影响设备运行,更危害着人类健康。通过介绍生物质热解焦油的特性及危害、对比分析目前各种不同除焦方法(文丘里法、旋风分离法、电捕焦法、高温裂解法和催化裂解法)的特点及应用前景,得出采用多种方法组合的形式进行联合除焦可显著提高焦油脱除效率。寻找用于湿法除焦的可再生利用的有机溶剂,开发经济、高效、长寿命的催化剂将成为生物质热解焦油脱除技术开发的重点。

Research progresses on removal of tar in biomass pyrolysis |

| Abstract: | Tar in biomass pyrolysis can not only reduce pyrolysis efficiency,impact equipment operation,but also harm human health. Based on the introduction of characteristics and harms of biomass pyrolysis tar and the comparatively analysis of features and application prospects of different processes for tar removal(such as:Venturi process,cyclone separator process,electric tar catcher process,high-temperature pyrolysis process and catalytic cracking process), it is pointed that the tar removal efficiency can be significantly improved by the combined tar-removal process,and the key points for future research of biomass pyrolysis tar removal technologies are as follows:finding recyclable organic solvent for wet tar-removal and developing economic,efficient and long-life catalyst. |
