Abstract

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.
