Abstract: A process includes periodically or continuously introducing an olefin monomer and periodically or continuously introducing a catalyst system or catalyst system components into a reaction mixture within a reaction system, oligomerizing the olefin monomer within the reaction mixture to form an oligomer product, and periodically or continuously discharging a reaction system effluent comprising the oligomer product from the reaction system. The reaction system includes a total reaction mixture volume and a heat exchanged portion of the reaction system comprising a heat exchanged reaction mixture volume and a total heat exchanged surface area providing indirect contact between the reaction mixture and a heat exchange medium. A ratio of the total heat exchanged surface area to the total reaction mixture volume within the reaction system is in a range from 0.75 in−1 to 5 in−1, and an oligomer product discharge rate from the reaction system is between 1.0 (lb)(hr−1)(gal−1) to 6.0 (lb)(hr−1)(gal−1).

Abstract: A system and a method for a constant micro dosing of powder material include a control device, a cylinder with a first opening and a piston movably arranged inside the cylinder and controllable by the control device. The piston is movable in the direction to or away from the first opening along a piston stroke direction. The cylinder stores the powder material between the piston and the first opening. The piston pushes the powder material through the first opening by moving along the piston stroke direction. Further the system and the method include a removing device for removing the powder material which is pushed out of the first opening of the cylinder. The control device controls the piston and the removing device in a synchronized manner such that a predetermined amount of powder material pushed through the first opening is removable by the removing device.

Abstract: Carbon particles are disclosed, as well as methods and systems for forming the particles. In one embodiment, the system may include a receiving vessel configured to receive a liquid carbon precursor and at least one orifice at a bottom of the receiving vessel and configured to release droplets of the precursor. A cooling vessel may be positioned below the receiving vessel to receive the droplets and configured to hold a coolant for solidifying the droplets into carbon precursor particles. The method may include introducing a liquid carbon precursor into a tank having a plurality of orifices defined therein such that droplets of the precursor are released from the orifices and solidifying the droplets in a cooling vessel positioned to receive the droplets from the orifices. The method may then include carbonizing the solidified droplets to form carbon particles. The particles may be solid or hollow.

Abstract: A thermal convection generating chip (1) includes a rotatory body (2), a thermal convection pathway (11) provided in the rotatory body (2), and a supply path (12A to 12C) that supplies a liquid to the thermal convection pathway (11). The supply path (12A to 12C) includes a liquid receiving section (121) that receives the liquid and a suction passage (122) that provides communication between the liquid receiving section (121) and the thermal convection pathway (11). The suction passage (122) has a first region (122a) extending between a midsection of the suction passage (122) and the thermal convection pathway (11), and a second region (122b) extending between the midsection and the liquid receiving section (121). The liquid in the first region (122a) is separated from the liquid in the second region (122b) through rotation of the rotatory body (2) to be supplied to the thermal convection pathway (11).
