Production of liquid fuels from low-temperature coal tar via hydrogenation over CoMo/USY catalysts

In the present work, CoMo/USY catalysts with various Mo loading were prepared by ultrasonic-assisted incipient-wetness impregnation method and characterized by XRD, BET, SEM, TEM, EDX-Mapping, H 2 -TPR, NH 3 -TPD and Py-FTIR techniques. The catalytic performance was investigated for hydrogenation of low-temperature coal tar. The product distribution including gaseous and liquid hydrocarbon was determined. The total light oil (≤ 300 °C) yield was 90 wt% with gasoline fraction (≤ 180 °C) of 47 wt% and diesel fraction (180–300 °C) of 43 wt%. Sulfur and nitrogen contents of below 10 and 50 μg g −1 in gasoline fraction,
