摘要

摘要: 将活性炭纤维吸附回收工艺应用于油页岩热解气轻质油品回收,自行建立了移动床油页岩连续热解实验装置及相应的油品回收系统。实验结果表明,冷凝冷却至室温的桦甸油页岩热解气中轻质油品含量可达20 g/m³以上。通过活性炭纤维吸附,可将煤气中的轻质油品完全回收。竞争吸附实验表明,"轻油"中的BTX、乙苯、C_10~13的烷烃、烯烃等更容易吸附,碳数相对较低的烯烃、烷烃、环烷烃吸附能力相对较弱。这将为油页岩热解气轻油高效回收工艺开发提供基础数据。

Abstract: A process of light oil recovery from oil-shale pyrolysis gas by using active carbon fiber adsorption was explored, and a moving-bed pyrolysis apparatus and a light oil recovering system were set up. By cooling the gas to room temperature and condensation, more than 20 g/m³ of light oil faction during the pyrolysis of Huadian oil shale are obtained. The light oil can be recovered completely by using the activated carbon fiber adsorption. The competitive adsorption of various compounds by activated carbon fiber shows that benzene, toluene, xylene, ethylbenzene and the hydrocarbons with more than ten carbon atoms are absorbed strongly, while the alkane, olefin and cyclane with six to nine carbon atoms are absorbed weakly. The research can provide fundamental data to the process development of light oil recovery from oil-shale pyrolysis gas.
