Publication number: 20200407651Abstract: Increased paraxylene production through the use of a split feed reforming process, wherein hydrotreated naphtha is split into light, middle and heavy fractions. Each fraction is reformed separately to generate streams containing aromatic compounds. These streams can further be processed and can undergo dealkylation, transalkylation, disproportionation, isomerization, and separation steps to maximize paraxylene production. In addition, some streams are recycled or recombined in order to maximize paraxylene production.Type: ApplicationFiled: June 27, 2019Publication date: December 31, 2020Inventors: Yufeng He, Qi Xu

Patent number: 10509222Abstract: A multi-directional bar code scanning device having multiple laser emitters matched with a single photosensitive receiver is disclosed. Multiple paths of laser beams generated by N laser emitters are projected towards a rotatable reflector group via a light projection reflector, and the rotatable reflector group projects the laser beams towards tilted reflector groups, such that multiple paths of laser scanning beams are generated and projected towards a bar code. A beam scatter by the bar code is reflected reversely towards a light collection reflector and focused on a single photosensitive receiver. The device can increase the number of scanning beams and the scanning directions, thereby expanding the scope of depth of field, and preventing the issues which multiple photosensitive receiver cannot operate simultaneously when a single channel is utilized and preventing non-coaxial optical signal crosstalk, thus improving decoding speed, and lowering the cost of the device.Type: GrantFiled: January 11, 2017Date of Patent: December 17, 2019Assignee: SUNLUX IOT TECHNOLOGY (GUANGDONG) INC.Inventors: Long Xu, Yufeng Li, Fanchun Zeng
