Table 2  Results of DYC-01 Catalyst on ACE Unit

　*催化剂经100%水蒸汽，17小时，800℃老化处理；
*Catalyst steamed at 800℃/100% steam/17h;
　　从表2结果可以看出：在相同反应评价条件下，DYC-01催化剂的转化率比对比渣油催化剂高2.09个百分点，焦炭产率相当，汽油+柴油收率和总液收分别提高1.4个百分点，液化气+汽油+柴油收率和总液收分别提高1.85个百分点，油浆下降1.60个百分点。充分显示了DYC-01催化剂优良的渣油催化裂化和抗重金属污染的性能。
　　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.
　　上述结果表明：DYC-01催化剂不仅具有很好的物化性能指标，而且具有很好的催化裂解高金属和高碱性氮含量的劣质渣油的能力。我们相信，选用DYC-01催化剂，必将会提高重油催化裂化装置的经济效益。
　　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.
