摘要: 通过研究菜籽饼的工业分析,发现挥发分比例较高适合对其热解利用,采用热重分析方法分析了厨菜籽饼的热解特性,提出了菜籽饼两段式热解转化利用的思路。在回转炉中对菜籽饼进行热解反应并分析了500 ℃下固液产物的组成和性质,发现固液产率较高,焦油及焦炭品质较好,具有广阔发展前景,为菜籽饼大规模地资源化利用提供了一条新的道路。

Abstract: Rapeseed residues can be utilized by means of pyrolysis due to its high content of volatile components. A thermogravimetric analysis was carried out to investigate the pyrolysis characteristics of rapeseed residues. A two-segment rotary furnace processing method was used for pyrolysis of rapeseed residues. The pyrolysis products in the rotary furnace at 500℃ were analyzed . The yields of solid and liquid product were high,and the fuel oil and coke products were both of good quality with broad prospects for future development,which offered a new approach to accomplishing the reutilization of rapeseed residue.
