摘要：A series of NiMo/A1203 catalysts with Mo loadings of 5°o-20% were prepared by direct reduc- tion of the corresponding molybdenum phosphate precursors. The usability of catalyst for pyrolytic oil hydrorefining was tested at the following parame- ters: temperature (290—350°C)_, LHSV (0.5—2.0 If‘) and 3-6 MPa pressure. The 15% of Mo loadi11g catalyst was most active, the conversion of pyridine, thiophene and cyclehexene could reach 99.18%, 98.75% and 100% respectively. The preparation method that y-A1203 was added in at the same time is better than other methods.
