Abstract: 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.

Abstract: A vehicle type identification method and device based on mobile phone data for solving the problem of providing a convenient and low-cost vehicle type identification method. The method includes: obtaining trajectory data recorded by a mobile phone of a user within a period of time; judging mobile phone users who are on the same vehicle according to the data, and obtaining a vehicle trajectory and the number of passengers corresponding to the vehicle trajectory; obtaining a vehicle origin and destination according to the vehicle trajectory, and obtaining an origin-destination type of the vehicle trajectory in combination with geographic data; obtaining vehicle driving data according to the vehicle trajectory; and obtaining service area data of vehicle staying according to the vehicle trajectory. The cost of obtaining data by using mobile phone big data and by using mobile phone signaling data collected and provided by an operator is low.

Abstract: 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.
