1环戊烷在Silicalite-1上吸附的热力学研究显示文摘 用智能重量分析仪测定了环戊烷在Silicalite-1上的吸附等温线,根据吸附等温线数据计算了热力学参数(吸附热Qst、熵变ΔS、Gibbs自由能变ΔG)。423K时,吸附等温线符合Langmuir方程。254,274K时,吸附等温线出现了滞后环。与分子构型相近的苯与环己烷相比,环戊烷的饱和吸附量超乎寻常,Qst、ΔG、ΔS随吸附量的变化较大,表明环戊烷在Silicalite-1上的吸附机理相当复杂。在吸附过程中,吸附质分子之间、吸附质和Silicalite-1之间的相互作用较强,环戊烷分子发生了重排。当吸附量达到1.5mmol/g时,吸附相开始凝聚,吸附热逐渐达到了凝聚热值。段林海 蒋施 孙兆林 张晓彤 宋丽娟 Rees L V C 2003石油化工高等学校学报2003,16,3:4
2正己烷在ZnNi/HZSM-5上微波芳构化显示文摘 研究了常规加热和微波辐射两种加热方法对正己烷在ZnNi/HZSM-5催化剂上的芳构化反应的影响。考察了温度、空速对反应性能的影响,并利用XRD对ZnNi/HZSM-5催化剂作了表征。结果表明,金属锌和镍高度分散于HZSM-5沸石中,微波辐射对分子筛结构的影响很小。与常规加热反应相比,要达到相同的芳烃收率,在微波加热条件下能使反应温度降低约100℃左右。在一定程度上提高反应温度可以获得较高的总芳烃收率和BTX收率,亦能明显地改变BTX中各组分的相对选择性。改变空速能显著影响总芳烃收率和BTX收率,在常规加热和微波加热条件下的最佳空速分别为1.5h-1和1.0h-1。讨论了正己烷在微波辐射下ZnNi/HZSM-5上的芳构化反应机理。正己烷首先裂解为C03+C=3,一部分烯烃齐聚、环化生成芳烃,另一部分烯烃则经氢转移或加氢生成烷烃,C03和C04在锌和镍活性中心上直接脱氢二聚环化生成芳烃。许健 张晓彤 桂建舟 罗有训 孙兆林 Rees L V C 2003石油化工高等学校学报2003,16,2:3
