Embodiment 1
[0074] This embodiment provides a lap bed reactor, such as figure 1 As shown, including:
[0075] Reactor housing 102 for accommodating the paste bed 101;
[0076] A multi-stage fractal gas distributor 103 for distributing the reactant gas into a multi-scale reactant bubble, the multi-stage fracture gas distributor 103 is immersed in the lamination bed 101;
[0077] The heat exchange tube 104 for heat exchange with the reactants and maintains a preset temperature during the reaction, the heat transfer tube 104 is immersed in the slurry bed 101.
[0078] As an example, such as figure 1 As shown, the slurry bed reactor includes at least: reactor housing 102, multi-stage fractal gas distributor 103, and heat transfer tube 104. The reactor housing 102 is used to accommodate the lap bed 101, the multi-level fractal gas distributor 103, and the heat transfer tube 104 immersed in the slurry bed 101. Specifically, in the present embodiment, the slurry bed reactor is a vertically placed ca...
Embodiment 2
[0090] This embodiment provides a reaction method of a lap bed reactor, such as Figure 9 As shown, including the following steps:
[0091] 1) Provide a slurry bed reactor containing a slurry bed that further comprises a multi-stage fractal gas distributor and a heat transfer tube immersed in the slurry bed;
[0092] 2) Support the reactant gas to the multi-stage fracture gas distributor, and distribute the reactant gas into micron-stage bubbles and millimeters air bubbles by the multi-stage fracture gas distributor;
[0093] 3) Make the micron-stage bubble and the millimeter bubble pass through the restrictive heat pipe where the micrometer bubble and the millimeter bubble are thermally exchanged and reactive to form a product gas.
[0094] In step 1), see Figure 9 S1 step and figure 1 There is provided a lap bed reactor containing a slurry bed 101, and the slurry bed reactor further comprises a multi-stage fractal gas distributor 103 and a heat exchange tube 104 that is immersed ...
Embodiment 3
[0099] In this example, the reaction method of the pulp bed reactor and the second embodiment of the second embodiment will be described in the reaction method of the pulley bed reactor.
[0100] In the present embodiment, the reactor housing of the gas bed reactor is 2 meters, an axial height of 35 meters, and a gas-liquid solid separation device is provided with a gas-liquid solid separation device, a heat transfer tube. Heating medium circulation pipeline Figure 7 The "four-leaf" type bionic geometry is provided with a multi-stage fractal gas distributor at the bottom of the paste bed reactor.
[0101] Before the start of the reaction, a slurry bed is pre-provided in the reactor housing, and the liquid surface of the slurry bed is located 15 meters above the multi-stage fractal gas distributor, and the slurry bed is liquid. Paraffin as a solvent, the catalyst is a cobalt-based catalyst, and the mass fraction of the catalyst is 5%.
[0102] During the reaction, the reactant gas ...
