2023年第6期广东化工第50卷总第488期www.gdchem.com·25·基于超临界甲醇的页岩油加氢特性研究邱腾龙1，李宇航1，白小薇1，徐国洪1，李建1,2*(1．新疆大学化工学院，新疆乌鲁木齐830046；2．独山子石化公司研究院，新疆克拉玛依838621)[摘要]页岩油作为常规油气资源的重要补充，其物理化学特性与常规石油有显著区别，传统石油转化理论无法完全适用于页岩油转化，因此，研究页岩油清洁转化意义重大。本文利用超临界甲醇对页岩油进行加氢精制，探究了CuMgAlOx催化剂、反应时间、反应温度对页岩油超临界甲醇加氢过程中的调控作用。结果发现，页岩油原料通过超临界甲醇加氢处理后，不饱和成分显著减少，而饱和组分增加，其中烯烃与酮类组分含量由25.8%和14.2%下降为11.6和0%，而烷烃含量则由27.7上升至36%；经过超临界甲醇加氢脱氧反应后液体产物中沸点低于350摄氏度的由89.06%，上升为95.84%。反应温度越高，反应时间越长，页岩油轻质化越明显，碳链长度为7~11的产物比例越高。[关键词]页岩油；超临界甲醇；CuMgAlOx；加氢反应；催化[中图分类号]TE624[文献标识码]A[文章编号]1007-1865(2023)06-0025-03StudyontheHydrogenationCharacteristicsofShaleOilBasedonSupercriticalMethanolQiuTenglong1,LiYuhang1,BaiXiaowei1,XuGuohong1,LiJian1,2*(1.InstituteofChemicalIndustry,XinjiangUniversity,Urumqi830046；2.ResearchInstituteofDushanziPetrochemicalCompany,Karamay838621,China)Abstract:Asanimportantsupplementtoconventionaloilandgasresources,thephysicalandchemicalpropertiesofshaleoilaresignificantlydifferentfromconventionaloil.Thetraditionaloilconversiontheorycannotbefullyappliedtoshaleoilconversion.Therefore,itisofgreatsignificancetostudythecleanconversionofshaleoil.Inthispaper,shaleoilwashydrotreatedwithsupercriticalmethanol,andtheregulatoryeffectsofCuMgAlOxcatalyst,reactiontime,andreactiontemperatureonshaleoilsupercriticalmethanolhydrogenationwereinvestigated.Theresultsshowedthataftersupercriticalmethanolhydrogenation,theunsaturatedcomponentsofshaleoilfeedstockdecreasedsignificantly,whilethesaturatedcomponentsincreased.Thecontentofolefinsandketonesdecreasedfrom25.8%and14.2%to11.6and0%,whilethecontentofalkanesincreasedfrom27.7%to36%;Aftersupercriticalmethanolhydr...
