摘　　要：中国石油独山子石化公司(简称独山子石化)500 kt/a催化重整(简称重整)装置使用半再生重整催化剂PRT-C/PRT-D累计运转近10年后,由于催化剂上碳含量、铁含量增加明显,催化剂反应性能下降,使得产物中C_(5)+稳定汽油收率下降2~3百分点,装置效益降低。对该装置采用中国石化石油化工科学研究院最新开发的SR-1000催化剂时的加工效果进行了模拟计算,结果表明:在C_(5)+稳定汽油的研究法辛烷值(RON)达到95的相同条件下,与该装置使用PRT-C/PRT-D催化剂相比,使用SR-1000催化剂时的C_(5)+液体收率提高3百分点,纯氢产率提高0.4百分点,循环氢纯度提高3.9百分点。SR-1000催化剂在提高C_(5)+稳定汽油收率和氢气产率方面具有明显优势,装置催化剂更换为SR-1000催化剂后每年可增加经济收益2077.46万元。Nearly 10 years after using semi-regenerative reforming catalysts PRT-C/PRT-D in 500 kt/a catalytic reforming unit of PetroChina Dushanzi Petrochemical Company,because of the increase of the carbon and iron content on the catalyst,the yield of C_(5)+stabilized gasoline was decreased by 2-3 percentage points and the benefit of the unit was decreased.The simulation calculation of the processing effect of SR-1000 catalyst,which was newly developed by the SINOPEC Research Institute of Petroleum Processing,was carried out.The results show that the RON of C_(5)+stabilized gasoline reaches 95 under the same conditions.Compared with PRT-C/PRT-D catalyst,the liquid yield,the pure hydrogen yield,recycle hydrogen purity of SR-1000 catalyst are increased by 3,0.4 and 3.9 percentage points,respectively.The SR-1000 catalyst has obvious advantages in increasing the C_(5)+gasoline and hydrogen.The economic profit of SR-1000 catalyst will be increased by 20.775 million yuan per year.
