The patients were followed - up and were performed measurement of residual urine and UFR after operation .

术后随访，行残余尿、尿 流率测定。

The up flow reactor ( UFR ) hydrogenation technology imported from Chevron Company was combined with the VRDS unit of Shengli Refinery Qilu Petrochemical Company at the capacity expansion revamping and had run 2 cycle totally 941 days .

齐鲁石化公司胜利炼油厂 VRDS扩能改造引进了Chevron公司 上流式反应器（ UFR）加氢技术，构成UFR/VRDS组合工艺，该装置已运转2周期941天。

Application of UFR in VRDS process

上流 式 反应 器在VRDS工艺中的应用

Presents technology processes and operation of the catalysts in VRDS and UFR / VRDS units .

介绍VRDS和 UFR/VRDS 装置的工艺流程及催化剂的运行情况。

Methods The UDS was performed in 102 patients with BPH which included Uroflowmetry ( UFR ) Filling cystometry ( CMG ) pressure flow study measurement of residual urine analysis of bladder outlet obstruction ( BOO ) .

方法对102例BPH病人进行详细尿动力学检查，包括尿 流率、充盈期膀胱测压、压力-流率测定、残余尿测定， 应用 P-Q 图进行分析是否存在膀胱出口梗阻。

The results show that UFR can greatly optimize the operation of VRDS reduce the operating severity effectively prolong operating period and improve economic results of the plant .

结果表明： UFR 技术可以极大地优化VRDS 装置的运转，减少 装置运转的苛 刻度，有效地延长 装置运转周期，提高装置的经济效益。

The RHT series catalysts were commercially manufactured and applied in the fixed-bed reactor of the 1.5Mt/a UFR / VRDS unit .

这些催化剂进行了工业生产，并在1.5Mt/a UFR/VRDS渣油加氢装置的固定床反应器中进行了工业应用。
