两段式回转炉热解菜籽饼

Research on pyrolysis of rapeseed residue in two-segment rotary furnace

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。

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.
