摘　　要：0.1Mt/a的C5/C6正构烷烃异构化工业放大试验装置以连续重整装置的拔头油为原料,采用脱异戊烷异构化反应组合工艺流程。实际生产表明,该装置的设计是成功的,装置的主要指标、装置能耗与设计值基本相符。采用的CI50催化剂为载钯催化剂,该催化剂性能良好,活性和稳定性都较高,能满足工业生产的要求。运行期间,反应进料的RON提高10个单位(达80),稳定塔塔底油(异构化产品)RON达83.2;C5异构化率达60%以上;C6异构化率达80%以上;C6选择性约20%;裂解率小于3%。Topped oil of CCR unit has been used as feedstock and the deisopentane isomerization reaction combined process has been adopted in the 2 000 b/d C 5/C 6 isomerization commercial test unit. Practical production shows that it is a successful design. Main targets and energy consumption of the unit correspond to the design value. Palladium catalyst CI 50 adopted in the test has good performance, higher activity & stability and the requirements of commercial production have been met. In the running, RON of the feedstock has been increased by 10 units, and has reached 80. RON of stabilizer bottom oil (isomerization product) has reached 83.2 and the rates of C 5 and C 5 isomerization are over 60% and 80% respectively. C 6 selectivity is about 20% and the hydrogenolysis rate is less than 3%.
