CHARACTERISTIC RESEARCH ON THE LIQUID PRODUCT FROM CO-HYDROTHERMAL LIQUEFACTION OF OILY SCUM AND LIGNOCELLULOSIC BIOCHARJournal:
THERMAL SCIENCESummary:
Hydrothermal liquefaction (HTL) is an effective way to treat solid wastes with high moisture content. The co-hydrothermal liquefaction (co-HTL) experiments of oily scum (OS) and poplar sawdust biochar (BC) at the different hydrothermal temperatures were performed in this work. The changes of the appearance and components of the liquid products were comprehensively studied. The results showed that the addition of BC into OS significantly reduced the moisture content of the residue hydrochars obtained after co-HTL. As the hydrothermal temperature increased, the liquid products obtained from co-HTL turned clearer and lighter in color, and the recovery rate of the liquid products significantly increased. The co-HTL of BC and OS could effectively improve the liquid quality and enhance the recovery rate of hydrochars. The carbon numbers of the liquid products obtained from co-HTL were concentrated in C5-C11, which were main compositions of gasoline. This work can provide basic data and theoretical reference for OS efficient treatment and engineering practice.Co-author:
