摘要：
Stillage from ethanolic fermentation of barley was converted directly into liquid fuel (primary oil) in the presence of sodium carbonate as a catalyst. The primary oil with a heating value of 36 MJ kg-1 was obtained in 38% yield at 300-degrees-C, N2 pressure of 12 MPa, a holding time of 0 min, and a catalyst loading of 2.5 wt%. To reduce high viscosity and oxygen, nitrogen, and sulfur content, the primary oil was hydrotreated with a Ni-Mo/Al2O3 catalyst at an initial H-2 pressure of 10 MPa. At 350-degrees-C and holding time of 4 h, the upgraded oil, competitive with petroleum oil, was obtained in 43% yield, and its properties were: heating value, 46 MJ kg-1; oxygen content, 0 wt%; nitrogen content, 3.6 wt%; sulfur content, 0.07 wt%; and viscosity, 62 cP(@ 50-degrees-C).
