FCC Additive DYC-PA for More Light Olefin

催化裂化装置一般使用含有择形分子筛的增产轻烯烃助剂来多产轻烯烃,同时也涌现了多种FCC多产丙烯工艺,如国内的HCC,DCC,CPP,FDFCC,MIP-CGP、TMP等工艺,国外的PetroFCC,Maxofin,Superflex,SCC,HS-FCC,等工艺。这些技术的反应化学基础是将汽油馏分择形裂化生成丙烯等轻烯烃。为了满足市场对轻烯烃日益增长的需要,6165金沙总站与国内科研机构合作,通过对活性组分和载体的选择、改性、活化和制备工艺等多方面的研究,共同研究开发了性能优异的增产丙烯催化裂化助剂DYC-PA。
  The additive for more light olefin with shape-selective molecular sieve is applied to FCCU, and meanwhile, several FCC technologies for more propylene emerge such as domestic HCC, DCC, CPP, FDFCC, MIP-CGP, TMP, etc., as well as foreign PetroFCC, Maxofin, Superflex, SCC, HS-FCC, and so forth. The chemical basis for the reaction of such technologies is to produce propylene and other light olefin with shape-selective cracking of gasoline fraction. In order to meet the increasingly demand for light olefin in the market, Shandong Duo You Technology Co., LTD developed FCC additive DYC-PA with excellent performance for more propylene jointly with domestic scientific research institutions through research of active components and carriers in selection, modification, activation preparation technology and other aspects.
一、物化性质
I. Physical and Chemical Properties

表1  DYC-PA轻烯烃助剂的质量指标
Table 1  Quality Index of DYC-PA

从表1的数据可以看出,DYC-PA增产轻烯烃裂化助剂的磨损指数、表观堆密度和粒度分布等物理性质与常规FCC催化剂相当,完全可以适应催化裂化装置正常操作对催化剂的要求。
  Table 1 shows that the attrition index, apparent bulk density, particle size distribution and other physical properties of cracking additive DYC-PA for more light olefin remain the same with conventional FCC catalyst, completely sufficient for requirements of catalyst by normal operation of FCC unit.
二、ACE催化裂化性能评价
II. FCC Performance Evaluation of ACE
  以重油催化裂化装置平衡剂作为主剂,分别掺入3.0wt%含量的DYC-PA增产轻烯烃裂化助剂、进口增产丙烯助剂和3.0wt%含量的国内常规产气助剂,在小型固定流化床装置(ACE)上进行催化性能评价,评价结果见表2。
  Take RFCC unit poiser as the main agent, mixed with 3.0wt% DYC-PA cracking additive for more olefin and imported propylene enhancing additive, as well as 3.0wt% domestic conventional gas additive, and conduct catalytic performance evaluation on ACE, and see Table 2 for evaluation results.

Table2  The Catalytic Performance Evaluation on ACE between DYC-PA and Other Similar Additives

* 原料油:20%VR+80%VGO
  Raw oil: 20%VR+80%VGO
  表2的评价结果说明:
(1)添加DYC-PA助剂对装置的干气、油浆及焦炭产率等基本无影响,也不会影响装置的处理量。
(2)DYC-PA助剂活性较高,所需的添加比例小,单耗低,具有良好的性价比。
(3)添加DYC-PA助剂能提高催化汽油的辛烷值,对催化汽油的烯烃含量影响不大。
(4) DYC-PA助剂具有适宜的裂化活性和优良的轻烯烃选择性,可以明显提高液化气和C3、C4轻烯烃产率。
  Table 2 shows that:
(1)Addition of DYC-PA additive basically has no influence on yield of dry gas, slurry oil and coke in the unit, neither on treatment capacity of the unit.
(2)DYC-PA additive is of comparatively high activity, with small adding proportion, low unit consumption and excellent cost performance.
(3)Addition of DYC-PA additive promotes octane number of catalytic gasoline, with little influence on olefin content of catalytic gasoline.
(4)DYC-PA has suitable cracking activity and excellent light olefin selectivity, greatly raising the yield of LPG as well as C3 and C4 light olefin.
