Example Embodiment

[0029] Example 1

[0030] Refer Figure 1-4 A supercritical fluid reaction system, alkali-based metal carbon preparation device, including the bottom frame 1, welded the L-shaped bracket 5 on both sides of the bottom frame 1 near the intermediate position, and one side welding of the L-bracket 5 has two The mounting frame 15, one side of the mounting frame 15 is connected by a bolt, and a heating mechanism is provided at the bottom of the reaction barrel 13, and the top welding of the reaction tub 13 is welded to the entry and exit tube 19, and the top of the entry and exit tube 19 is inserted with a seal. The cover 18, the top of the sealing cover 18 is connected to the motor 12 by a bolt, and the output shaft of the motor 12 welcomes the rotating shaft 20, and the outer wall of the rotating shaft 20 welded to the bearing housing, the outer wall of the bearing housing welded with an equal distance distribution connecting rod 25, connecting rod The bottom of the 25 is connected by a b

Example Embodiment

[0039] Example 2

[0040] Refer Figure 5 In a supercritical fluid reaction system, alkali-base metal carbon preparation devices, this embodiment, compared to the first embodiment, the bottom inner wall of the bottom frame 1 is connected to the heat transfer cover 28 wrapped in periphery of the heating coil 24, and thermally conductive The cover 28 is provided as a spherical structure.

[0041] Working principle: When using the user, the user can heat the CO2 and the heating coil 24 via the heater 23 and the heating coil 24 to isolate the CO2 and the heating coil 24 by the heat shield 28 to avoid the direct and heating plates of CO2. A sharp expansion problem occurs when the tube 24 is in contact, preventing an unstable problem due to changes in the gas pressure inside the reacted barrel 13.

Abstract

The invention discloses an alkali metal carbon preparation device in a supercritical fluid reaction system. The device comprises a bottom frame, L-shaped brackets are welded on two sides of the top, close to the middle position, of the bottom frame, two mounting racks are welded on one sides of the L-shaped brackets, one sides of the mounting racks are connected with a reaction barrel through bolts, a heating mechanism is arranged at the bottom of the reaction barrel, an inlet-outlet pipe is welded to the top of the reaction barrel, a sealing cover is inserted into the top of the inlet-outlet pipe, a motor is connected to the top of the sealing cover through bolts, and a rotating shaft is welded to an output shaft of the motor. In an scCO2 system, safe and nontoxic CO2 is used as a carbon source, metal sodium is used as a reducing agent, CO2 is reduced into colorless and transparent base metal carbon after 12 hours of reduction reaction under the supercritical conditions of 440 DEG C and 80 MPa, the activity performance of the metal sodium is improved, the metal sodium is in sufficient and rapid contact with CO2, and the speed of the reduction reaction is increased.
