Embodiment 1
[0066] This example is used to illustrate the catalyst continuous reduction device and the reduction method of the iron-based Fischer-Tropsch synthesis catalyst of the present invention.
[0067] refer to figure 1 , the iron-based Fischer-Tropsch synthesis catalyst to be reduced is added in the storage tank 2 through the catalyst inlet 23 arranged on the storage tank 2, wherein the storage tank 2 also has a catalyst outlet 20; the catalyst outlet 20 is connected to the rotary reactor A sealed catalyst delivery channel 25 is provided between the feed ports 11 of the reactor 1; the sealed catalyst delivery channel 25 communicates with the feed port 11 of the rotary reactor 1 in a dynamic seal. Wherein the storage tank 2 is provided with a first inert gas inlet 21, a vacuum suction port 22 and a weighing scale 26; the effect of the weighing scale 26 is to measure the quality of the catalyst entering the reduction reactor; The gas brought in by the catalyst is introduced into the...
Embodiment 2
[0075] This example is used to illustrate the reduction method of cobalt-based Fischer-Tropsch synthesis catalyst.
[0076] The device and method of Example 1 were used to reduce the catalyst, except that the catalyst to be reduced was the cobalt-based Fischer-Tropsch synthesis catalyst as described above. And among them, the reducing gas is H 2 , the temperature in the rotary reactor 1 is 400°C, the pressure is 1MPa, and the volume space velocity of the reducing gas is 10000h -1 , the reduction time of the catalyst is 24h; the volume of the catalyst accounts for 10% by volume of the volume of the rotary reactor 1; the rotating speed of the rotary reactor 1 is 5 rpm; the aspect ratio of the rotary reactor 1 is 50:1. The reduced cobalt-based Fischer-Tropsch synthesis catalyst of this embodiment is obtained through reduction.
