The preparation and laboratory evaluation of phosphorus- contain hydrofining fine catalysts were reported. The catalysts' activity changed with the reaction conditions, such as hydrogen flow rate, space velocity, reaction time and reaction temperature. The catalysts' reaction activity changed wavelike with hydrogen flow rate change. Under the condition of model oil- 1, when hydrogen flow rate was at 26 mL/min, the catalyst' s activity, was the highest. Under the condition of model oil - 1, catalysts' activity changed greatly when space velocity was at the range 1 ~3 h-1.Stability of catalysts' activity was better under the condition of the model oil - 2. After 122 h on continuous flow reaction, catalysts' activity was not decreased. While under the condition of the model oil - 1, with the reaction time, the catalyst's HYD activity fell more obviously, HDS activity dropped a little, HDN activity almost didn't change. Catalysts' HDS and HYD activity was raised quickly when the temperature went up from 280℃ to 370℃ , but HDN activity had little wavelike when the temperature raised up. Experiments show that the catalyst's reaction activity is higher under the conditions of hydrogen partial pressure of 2.88 MPa, reaction temperature of 370℃ and space velocity of 1.7 h-1 using model oil - 1.
