提升管反应装置能够在石油加工的流程中发挥关键作用，有利于提高资源的利用率与整体生产质量。
但是，随着相关资源条件的劣化，整体反应效果受到了一定程度的负面影响。
此外，市场对于石油工业产品的要求也出现了严格化的趋势。
这些因素导致工业生产团队需要探索全新的应用技术，进一步强化整体加工效果。
石油炼制催化裂化提升管技术能够有效促进生产质量的提升，提高整体清洁程度，有利于加工行业的未来发展。
一、 提升管技术主要类型1.多段进料应用在提升管技术的主要类型中，多段进料形式属于一种常见的应用方案。
这种技术通过在差异化高度级别安装数个进料喷嘴的方式，有效提高原料加工的针对性，进一步强化分布要求的落实效果。
同时，还可以根据反映阶段的苛刻程度，如温度上升状态、压力、剂油比、反映速度等因素，确定回炼油的加入时间。
通过这种方式，可以有效控制生产油品的质量，促进柴油种类的拓展。
国外利用多段进料形式，开发了裂化多产轻烯烃的应用技术，对后续的多产液化气以及柴油MGD应用提供了开发条件。
这种工艺能够将裂化与催化的基础特征与对应的分组选择性、汽油裂化性进行深入结合，从而实现有机控制反应深度级别的效果，有利于整体进料与回炼的体系形成。
在提升管中，从底部区域到顶部区域分为四个主要反应位置，分别为汽油区、重油区、轻油区、反应控制区。
这些反应区可以通过适当的结合，达到良好的应用效果，进一步强化整体生产操作的灵活性。
2. MIP应用MIP生产工艺在20世纪末期出现，通过将单体提升管分割为两个对应的反应区域，有效增强整体生产效果。
第一个反应区域可以利用超高温将剂油比提升到一个良好的级别，从而有效实现降低接触时间的目标。
这种反映的基础苛刻程度高于常规裂化与催化反应，能够将重油快速转变为烯烃，进而降低基础生产副产物级别。
第二个反应区域可以利用固定层级的扩张提升管道，对催化剂的存储区域进行适当的反应沉降循环。
3.双提升管应用双提升管技术从传统FCC反应流程改进而来，经典应用流程中，FCC反应会受限于单体转化程度，回炼油的基础品质与原料状态也会产生一定的影响。
两段提升管催化裂化沉降器内待生剂吸附油气的变化刘熠斌;闫昊;孙晓昉;冯翔;杨朝合【摘要】沉降器内汽提油气的冷凝是造成重油催化裂化装置沉降器结焦的根本原因.为了分析待生剂吸附油气的性质变化,首先通过在线取样获得两段提升管催化裂化装置不同提升管内待生剂,用甲苯抽提提取待生剂上吸附的烃类并进行性质分析;然后在模拟汽提实验装置上进行待生剂的模拟汽提实验,分析汽提过程中的化学反应;最后将汽提油气中的液相组分进行二次热转化实验,探索汽提油气在沉降器稀相空间的热转化行为.结果表明,二段提升管待生剂吸附油气较多,馏程偏重,饱和分和氢含量很低;汽提过程中的化学反应以热裂化为主,二段待生剂吸附油气的反应较弱,重油收率较高,而且经过二次热裂化反应后,二段汽提油气重油收率仍然高于50％.因此二段提升管待生剂汽提油气会对两段提升管催化裂化沉降器的结焦产生重要影响.%Condensation of stripped hydrocarbons is the root cause of coking in the disengager of a fluid catalytic cracking unit.To analyze the property changes of stripped hydrocarbons,on-site sampling at an industrial two-stage riser fluid catalytic cracking (TSRFCC) plant was performed to get the spent catalysts from various risers.The spent catalyst was extracted with toluene as solvent to obtain adsorbed hydrocarbons,which were analyzed by various methods.The spent catalyst from riser was also stripped with steam as a medium,and the chemical reactions in stripping were investigated.The liquid of stripped hydrocarbons was gathered to carry out thermal cracking experiment to simulate the reaction in dilute phase zone in the disengager.The spent catalyst from 2nd riser contained more adsorbed hydrocarbons with high distillation range and lower saturate andhydrogen contents.Thermal cracking is the dominant chemical reaction in the stripping process.Yield of heavy oil was higher in the stripping of the 2nd riser spent catalyst due to the lower crackability of the adsorbed hydrocarbons.After secondary thermal cracking,the heavy oil yield of stripped hydrocarbon from the 2nd riser spent catalyst was still over 50％.Therefore,stripped hydrocarbon from the 2nd riser spent catalyst had a remarkable effect on coking in the disengager of the TSRFCC unit.【期刊名称】《石油学报（石油加工）》【年(卷),期】2017(033)005【总页数】7页(P842-848)【关键词】催化裂化(FCC);待生剂;吸附油气;汽提;化学反应【作者】刘熠斌;闫昊;孙晓昉;冯翔;杨朝合【作者单位】中国石油大学重质油国家重点实验室,山东青岛266580;中国石油大学重质油国家重点实验室,山东青岛266580;中国石油大学重质油国家重点实验室,山东青岛266580;中国石油大学重质油国家重点实验室,山东青岛266580;中国石油大学重质油国家重点实验室,山东青岛266580【正文语种】中文【中图分类】TE624Abstract： Condensation of stripped hydrocarbons is the root cause of coking in the disengager of a fluid catalytic cracking unit. To analyze the property changes of stripped hydrocarbons, on-site sampling at anindustrial two-stage riser fluid catalytic cracking (TSRFCC) plant was performed to get the spent catalysts from various risers. The spent catalyst was extracted with toluene as solvent to obtain adsorbed hydrocarbons, which were analyzed by various methods. The spent catalyst from riser was also stripped with steam as a medium, and the chemical reactions in stripping were investigated. The liquid of stripped hydrocarbons was gathered to carry out thermal cracking experiment to simulate the reaction in dilute phase zone in the disengager. The spent catalyst from 2nd riser contained more adsorbed hydrocarbons with high distillation range and lower saturate and hydrogen contents. Thermal cracking is the dominant chemical reaction in the stripping process. Yield of heavy oil was higher in the stripping of the 2nd riser spent catalyst due to the lower crackability of the adsorbed hydrocarbons. After secondary thermal cracking, the heavy oil yield of stripped hydrocarbon from the 2nd riser spent catalyst was still over 50%. Therefore, stripped hydrocarbon from the 2nd riser spent catalyst had a remarkable effect on coking in the disengager of the TSRFCC unit.Key words：fluid catalytic cracking (FCC); spent catalyst; adsorbed hydrocarbon; stripping; chemical reaction沉降器结焦是影响重油催化裂化装置长周期运行的重要原因。
