摘要: 在分析历年现场操作数据的基础上,总结PS Ⅵ重整催化剂的各项性能。结果表明:PS Ⅵ重整催化剂具有良好的耐磨性能、水热稳定性和持氯性能;催化剂初期活性高,稳定期运行寿命长,整个运行周期内,催化剂强度能够保持良好水平;适当控制PS Ⅵ催化剂较高的总氯含量,有利于得到更好的产品分布;重整进料中硫、氮和金属等杂质会影响催化剂性能,硫含量高时对催化剂积炭会产生较大影响,此时要考虑再生系统的烧焦能力;重整进料中的氮在反应系统中与氯发生反应生成铵盐,会对重整装置产物后分离设备和管道造成堵塞和腐蚀。

Abstract: Based on the historical operation data,the performance of PS Ⅵ reforming catalyst was summarized.The analysis indicated that the PS Ⅵ reforming catalyst has good wear resistance,hydrothermal stability and chlorine holding capacity.The initial activity of the catalyst is high along with a long stable service life and good catalyst strength.Keeping moderate higher Cl content on the catalyst is helpful to get better product distribution.The sulfur,nitrogen and metal impurities in feed affect the performance of the catalyst and higher sulfur in feed has worse effect on the carbon deposition,thus the coke burning operation conditions in the regeneration sector must be adjusted; The nitrogen in the reforming feed reacts with chlorine to produce ammonium salt,which causes the blockage and corrosion in the separation equipment and the pipeline of the reforming device.
