  • Patent number: 8361396
    Abstract: Embodiments of the present invention are directed to automated-polymer-synthesis systems that include discrete reagent-solution-addition, wait-time, and reagent-solution-draining sub-systems which together significantly increase throughput and decrease sub-system idle time. The automated-polymer-synthesis systems that represent embodiments of the present invention additionally include switches at points in which carriers can be received from multiple input paths or output to multiple different output paths. The automated-polymer-synthesis systems that represent embodiments of the present invention generally include an input spur and output spur in addition to a main loop, allowing carriers containing only completed polymers to be removed and new carriers input, so that carriers traverse the automated-polymer-synthesis systems independently from one another.

  • Patent number: 8101132
    Abstract: To provide a mixing device capable of effectively mixing stock oil with a catalyst, while increasing the amount of throughput, the relations of 8.0?Q×(W/D)/(u1+u2), Q=300 to 2000 [kg/m2s], W/D=0.2 to 0.5, u1=5 to 300 [m/s], and u2=5 to 300 [m/s] are satisfied when a mass flow per unit area of a moving bed is Q [kg/nes], the difference between an outer diameter and an inner diameter of the moving bed is W [m], an inner diameter of a reaction tube is D [m], a linear velocity of a horizontal component of the stock oil at a jet orifice of the internal stock oil injection nozzle u1 [m/s], and a linear velocity of a horizontal component of the stock oil at a jet orifice of the external stock oil injection nozzle u2 [m/s].
