Liang ZHAO, Yan CHEN, Jinsen GAO, Yu CHEN,

《化学科学与工程前沿(英文)》 2010年 第4卷 第3期   页码 314-321 doi: 10.1007/s11705-009-0271-9

摘要: This paper reviews the most important developments on the desulfurization mechanism of Fluid Catalytic Cracking (FCC) gasoline. First, the origin of sulfur compounds in FCC gasoline and the current developed desulfurization approaches and technologies are briefly introduced, and then the researches on desulfurization mechanism are summarized from experimental and theoretical perspectives. Further researches on the desulfurization mechanism will lay a foundation for optimizing desulfurization sorbents and technologies.

Constitutive Model for an FCC Single-Crystal Material

摘要:

Taking into account the effects that the components of tension stresses couple with components of torsion stresses when off-axis loads are applied to orthotropic materials, Hill s yield criterion for plastically orthotropic solids is modified by adding an invariant that is composed of the product item of quadratic components of the deviatoric stress tensor, and a new yield criterion is put forward in terms of the characteristics of the face-centered cubic (FCC) single-crystal material. The correlation of prediction and experiments is very good, and the new criterion is used to predict the yield stresses of an internal single-crystal, Nickel-based superalloy, DD3, which is more accurate than that of Hill s at 760?C. Equivalent stress and strain that adapt to the new criterion are defined. Thinking of the yield function as a plastic potential function from the associated flow rule, the elastic plastic constitutive model for the FCC single-crystal material is constructed, and the corresponding elastic plastic matrix is educed. The new yield criterion and its equivalent stress and strain will be reduced to Von Mises yield criterion and corresponding equivalent stress and strain for isotropic materials.

Gas-solids separation model of a novel FCC riser terminator device: super short quick separator (SSQS

LU Chunxi, LI Ruxin, SHI Mingxian, LIU Xiancheng

《化学科学与工程前沿(英文)》 2008年 第2卷 第4期   页码 462-467 doi: 10.1007/s11705-008-0068-2

摘要: The gas flow field and the separation efficiency of a novel fluid catalytic cracking (FCC) riser terminal device, named as Super Short Quick Separator (SSQS), were studied. On the basis of above investigations, a section-lateral-mixing separation model was proposed, which included both the effect of inertia and structure of gas outlet on particles capture. After final modification, the results predicted with this model could be in good agreement with the cold experimental data. According to this model, the separation efficiency of SSQS is mainly influenced by the difference between the arc radius and the center pipe radius as well as the magnitude of particle tangential velocity.

A novel fluid catalytic cracking process for maximizing

摘要: The maximizing iso-paraffins (MIP) developed by RIPP has improved gasoline quality to meet the demand of motor gasoline specification. A concept that two different reaction zones include cracking zone and conversion zone is proposed as the fundamental of MIP by research on fluid catalytic cracking (FCC) reaction chemistry. Based on the concept, the MIP process is featured by applying a novel sequential two-zone riser in conjunction with proprietary catalyst and engineering technique. The developed MIP process can not only improve gasoline yield or gasoline plus propylene yields but also produce gasoline with a higher content of -paraffins and a lower content of sulfur. A minimum octane number loss is achieved when MIP gasoline is treated by downstream desulfurization technology (RSDS/S Zorb). The combination of MIP and RSDS/S Zorb processes creates a very competitive route, which is different from the technical route used by other developed countries, to upgrade the quality of motor gasoline with the lowest economic costs in China. In just one decade, the processing capacity of MIP units has accounted for about 60% of the domestic total processing capacity of FCC units. The MIP process is gradually becoming a new generation of FCC technology.

催化裂化过程反应化学的进展

《中国工程科学》 2007年 第9卷 第8期   页码 6-14

摘要:

面对催化裂化工艺所遇到的挑战,提出了催化裂化过程反应化学的多维反应结构模式。多维反应结构模式的建立是基于对烃类在酸性催化剂上反应化学认识而进行的知识创新,但多维反应结构不同于烃类在酸性催化剂上反应化学。具有多维反应结构的催化裂化工艺更具有多样性和灵活性,基于此已成功地开发了多产异构烷烃的催化裂化工艺和生产清洁汽油和多产丙烯的催化裂化工艺。
