摘要
基于重油高效催化裂解(RTC)装置的工艺特点和产物分布需求,兼顾对开工催化剂流化性能、物化性能的要求,科学混配优选平衡剂组分、定制新鲜剂组分和惰性助剂,开发了定制开工剂TSC-R1.与传统的开工剂相比,定制开工剂物性指标优异,具有更高的丙烯因子和更低的焦炭选择性,可以快速匹配目标装置的开工需求.在中国石化安庆分公司3.00 Mt/a RTC装置上的工业应用表明,装置调整时间大幅缩短,装置仅需7 d即可达到稳定运行状态催化剂反应活性快速达到平稳,有助于装置的产品分布更快地达到设计工况,保证经济效益.
Abstract
Based on the process characteristics and product distribution of resid to chemicals(RTC)unit,while considering the demands for the fluidization performance and physicochemical properties of the start-up catalyst,a scientific blend of selected equilibrium catalyst component,customized fresh component,and inert auxiliary was developed to create the tailored start-up catalyst TSC-R1.Compared to traditional start-up catalyst,the tailored start-up catalyst has excellent physical properties,higher propylene factor and lower coke selectivity,and can quickly match the start-up requirements of the target plant,enhancing the economic benefits of the RTC unit.The industrial application of TSC-R1 in SINOPEC Anqing Petrochemical Company 3.00 Mt/a RTC unit showed that the adjustment time of the unit was greatly shortened,and the time for the unit to achieve stable operation was only 7 d.The quick and stable reaction activity of the catalyst is helpful for the product distribution of the unit to reach the design condition and ensures economic benefits.
