Publication number: 20210165030Abstract: Disclosed is a method for measuring trap parameters in an XLPE cable based on a polarization-depolarization current test. First a detrapping current is extracted from a polarization current, then the staged linear fitting is performed for the detrapping current. Fitting parameters Am·?m and ?m are used to represent trap parameters such as the trap charge density and the trap depth in the XLPE current. The trap charge density and charge accumulation of the XLPE cable insulation are reflected. This method can guarantee the accuracy and effectiveness of the trap parameter measurement. Furthermore, in the method, the staged linear fitting is performed for the detrapping current, providing an excellent fitting effect, effective elimination of various interference signals, and further accuracy improvement of the trap parameter measurement. In addition, the present disclosure is based on a PDC non-destructive test method.Type: ApplicationFiled: November 27, 2020Publication date: June 3, 2021Inventors: Kai Zhou, Hao Yuan, Mingzhi Li, Yuan Li, Hang Xi

Patent number: 10538711Abstract: A process for converting naphtha, lower olefin, light aromatic hydrocarbon, and gasoline with a high octane number by combining catalytic cracking of naphtha with steam cracking of lower alkane and catalytic cracking of higher alkanes and higher olefins. The process increases the yield of product with high value and significantly decreases the yield of low value product. At the same time, the power consumption is decreased as a whole since most reactants are converted in catalytic cracking at a lower temperature.Type: GrantFiled: June 2, 2015Date of Patent: January 21, 2020Assignees: SABIC GLOBAL TECHNOLOGIES B.V., DALIAN INSTITUTE OF CHEMICAL PHYSICS, CHINESE ACADEMY OF SCIENCESInventors: Peng Xie, Mingzhi Li, Yunpeng Xu, Guangye Liu, Zhongmin Liu, Haitao Liu
