摘要
从中型试验和工业应用两个方面对中国石油石油化工研究院兰州化工研究中心开发的LDR-100重油催化裂化催化剂的应用性能进行考察。中型试验结果表明,与参比催化剂相比,重油产率降低1.45百分点,丙烯收率提高0.74百分点,汽油辛烷值(RON)提高0.70个单位,汽油烯烃体积分数降低6.13百分点。工业应用结果表明,与基础催化剂相比,总液体收率提高0.42百分点,汽油辛烷值(RON)增加3个单位,催化剂单耗由2.24kg/t降低到1.76kg/t,经济效益可增加2 638.77万元/a。
The performance of LDR-100 FCC catalyst developed by Lanzhou Petrochemical Research Center of PetroChina was investigated on a riser pilot plant unit and applied in commercial FCC unit processing heavy feedstocks. The evaluation results of pilot plant riser unit showed that as compared with a commercial reference catalyst,its propylene yield increased 0.74 percentage points, the RON of its gasoline increased 0. 70 units, slurry oil yield reduced 1.45 percentage points and olefin volume fraction of gasoline reduced 6.13 percentage points. Commercial application results showed that compared with based case, the total liquid yield increased 0.42 percentage points,RON of gasoline increased 3 units,the consumption of catalyst reduced from 2.24 kg/t to 1.76 kg/t,an economical benefit of 26. 387 7 million RMB could be obtained annually.
