求“S Zorb装置汽油脱硫过程中吸附剂失活原因分析”论文？ 求“S Zorb装置 汽油脱硫 过程中吸附剂失活原因分析”论文，哪位兄弟有发一下，O(∩_∩)O谢谢！ S Zorb装置汽油脱硫过程中吸附剂失活原因分析 徐广通,刁玉霞,邹亢,张哲民 中国石化 石油化工 科学研究院 CAUSE ANALYSIS OF SORBENT DEACTIVATION IN S Zorb UNIT FOR GASOLINE DESULFURIZATION Xu Guangtong 摘要 参考文献 相关文章 Download: PDF (0KB) HTML (0KB) Export: BibTeX or EndNote (RIS) Supporting Info 摘要 针对S Zorb装置运行过程中出现的吸附剂失活快、剂耗高等问题，采用SEM、XRD、XRF、XPS、MAS-NMR等多种表征手段对不同形态吸附剂的物化性质进行系统的表征研究。结果表明：S Zorb装置运行过程中锌铝尖晶石和硅锌矿等非活性含锌物相的形成会导致吸附剂中有效ZnO含量的大幅降低，当ZnO的量降低到不足以完成吸附硫的转移时，工艺上即表现为吸附剂的失活和脱硫效率的降低。锌铝尖晶石的形成将导致吸附剂的强度下降，使吸附剂颗粒更易破碎，增加剂耗。在S Zorb装置运行过程中，对待生剂和再生剂物相组成变化的跟踪监测有助于保障装置的平稳运行，保持良好的脱硫效率。 Service 把本文推荐给朋友 加入我的书架 加入引用管理器 Email Alert RSS 作者相关文章 关键词 ： S Zorb吸附剂 吸附脱硫 表征 失活 锌铝尖晶石 硅锌矿 FCC汽油脱硫 Abstract ： Aiming at investigating the causes of fast deactivation and high consumption of sorbent in S Zorb process, the physicochemical properties of various sorbent samples were characterized by SEM, XRD, XRF, XPS and MAS-NMR techniques systemically. During the operation of S Zorb unit, the amount of active ZnO decreases significantly, due to the formation of non-activated gahnite, such as zinc aluminate, Willemite and etc. As long as the amount of active ZnO is not enough to support the transfer of sulfur containing compounds in gasoline, the sorbent is deactivated and its desulfurization function diminishes. In addition, the formation of zinc aluminate in sorbent may cause the particles to be fragile, thus the consumption of sorbent increases. It is suggested that monitoring the phase changes of spent and regenerated sorbent will be helpful to ensure an effective and stable running of the S Zorb unit.
