3、ACE催化裂化性能評價
3. Catalytic Cracking Performance of DYC- 01 Catalyst on ACE Unit
采用M100作為評價原料，在ACE反應評價裝置上對DYC-01催化劑的催化性能進行了評價。表2給出了催化裂化反應評價結果。
The catalytic performance evaluation of DYC-01 catalyst was carried out with M100 feed in ACE catalytic cracking testing unit. Results are listed in Table 2.
表2 ACE催化裂化評價結果
Table 2 Results of DYC-01 Catalyst on ACE Unit
*催化劑經100%水蒸汽，17小時，800℃老化處理；
*Catalyst steamed at 800℃/100% steam/17h;
從表2結果可以看出：在相同反應評價條件下，DYC-01催化劑的轉化率比對比渣油催化劑高2.09個百分點，焦炭產率相當，汽油+柴油收率和總液收分別提高1.4個百分點，液化氣+汽油+柴油收率和總液收分別提高1.85個百分點，油漿下降1.60個百分點。充分顯示了DYC-01催化劑優(yōu)良的渣油催化裂化和抗重金屬污染的性能。
Table 2 shows that under the same reaction conditions, compared with competitive RFCC catalyst, heavy oil conversion for DYC-01 catalyst was higher by 2.09%, gasoline+LCO yield and LPG+gasoline+LCO Yield is higher by 1.24% and 2.05%, respectively, meanwhile, coke yield remains the same, bottoms yield decreases by 1.60%. The results fully show that DYC-01 catalyst has better performance on both resid cracking and contaminant metals tolerance.
上述結果表明：DYC-01催化劑不僅具有很好的物化性能指標，而且具有很好的催化裂解高金屬和高堿性氮含量的劣質渣油的能力。我們相信，選用DYC-01催化劑，必將會提高重油催化裂化裝置的經濟效益。
Based on these results, the following observations can be made: DYC-01 catalyst combines good physical-chemical properties with high cracking conversion potential of resid containing high levels of metals and basic nitrogen. We believe that the application of DYC-01 catalyst will definitely enhance economic potential of RFCC unit.
