Publication number: 20240117255Abstract: A system for catalytic cracking of hydrocarbon oils has a catalytic cracking reactor, a catalyst separation device, an optional reaction product separator, and a regenerator. A catalytic cracking reactor has a dilute-phase transport fluidized bed and a fast fluidized bed connected in series for reaction. In the fast fluidized bed, the axial solid fraction ? of the catalyst is controlled within the range of about 0.1 to about 0.2. When used for catalytic cracking of hydrocarbon oil feedstocks, particularly heavy feedstock oils, the process and system show lower yields of dry gas and coke, and good product distribution.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: Jianhong GONG, Zhigang ZHANG, Xiaoli WEI

Publication number: 20140129727Abstract: The disclosure relates to an activation method for a data card and a data card. The data card has two activation modes: a network card activation mode and a U-disc activation mode; in the U-disc activation mode, only a U-disc related module is activated; and in the network card activation mode, the data card can be configured to access the internet via the interaction with an AT command in the data card without installing GUI software, and various operation systems can be compatible. When the data card is activated in the network card activation mode, an Ethernet card is enumerated directly without a switching process from the CDROM to the modem, thereby improving the activation speed of the data card. The Ethernet card device and the U-disc cannot function at the same time, so as to ensure that the limited bandwidth of a USB is completely used for data service.Type: ApplicationFiled: March 29, 2012Publication date: May 8, 2014Applicant: ZTE CORPORATIONInventor: Zhigang Wei

Patent number: 8649985Abstract: A method is provided for performing fatigue evaluation of a fatigue prone location of a tangible structure by converting multi-axial loading data of the fatigue prone location of the tangible structure to a set of equivalent constant amplitude loading data for the tangible structure. According to the method, a multi-axial load locus representing the tangible structure is generated. Time-dependent interior turning points R and any corresponding projected turning point R* art identified along the loading path from the point of origin P to the point of termination Q. Half cycles in the loading path are counted by referring to the interior and projected turning points R, R* along the loading path and to the point of origin P and the point of termination Q on the load locus. A stress range ??e, loading path length L, and virtual path length for each of the counted half cycles are determined.Type: GrantFiled: October 30, 2009Date of Patent: February 11, 2014Assignee: Battelle Memorial InstituteInventors: Pingsha Dong, Zhigang Wei, Jeong K.

Publication number: 20120102238Abstract: An auto start method and system for Universal Serial Bus (USB) data card. The method includes: when a terminal detects a data card is inserted, judging that the terminal does not install a driver of the data card, and using the default configuration mode to configure the data card and reading the content of the data card to install the driver; otherwise, using the driver of the data card to load the data card. After the PC finishes installing the related driver and software, the data card can directly start by the normal configuration when it is inserted again, therefore, the method can improve the auto start speed of the data card. Which kind of configuration is used to start the data card depends on the static configuration value in the registry, therefore, the performance of the method is reliable.Type: ApplicationFiled: December 10, 2009Publication date: April 26, 2012Applicant: ZTE CORPORATIONInventor: Zhigang Wei
