Problems solved by technology

Saturated impregnation is impregnated with the amount of impregnating liquid that can be absorbed by the catalyst carrier. This impregnation method has a low loading of active components; The impregnation method lacks the control of the impregnation process, the active components of the catalyst impregnated by this method are unevenly distributed, and the content of the active component load fluctuates greatly.

Embodiment 1

[0061] 1) Add 1000L of pure water into the impregnating liquid storage tank 1 through the feeding port 12, start the agitator 11 for stirring, add 200 kg of ammonium metatungstate (ammonium metatungstate with a tungsten oxide content of 82 wt%) and continue stirring for 10 minutes, Add 250 kg of nickel nitrate (nickel nitrate with a nickel oxide content of 24 wt%), stir for 10 min after the addition, replenish the solution to 1500 L, and stir for 30 min.

[0062] 2) Put the catalyst carrier to be impregnated into the carrier barrel 4 (the input amount of the carrier is 1 / 2 of the volume of the carrier barrel). The carrier barrel 4 is hoisted into the dipping tank 2 by means of an electric hoist.

[0063] 3) Turn on the delivery pump 31, pump the impregnating liquid in the impregnating liquid storage tank 1 into the impregnating tank 2, turn on the rotating motor, and make the rotation speed of the carrier barrel 4 be 15 rpm. When the immersion liquid in the immersion tank 2 r...

Embodiment 2

[0069] 1) Add 1000L of pure water into the impregnating liquid storage tank 1 through the feeding port 12, start the agitator 11 for stirring, add 175 kg of molybdenum trioxide (molybdenum trioxide with a molybdenum oxide content of 99 wt%), continue stirring for 10 minutes, and add nitric acid Nickel (nickel nitrate with a nickel oxide content of 24wt%) was stirred for 10 minutes after the addition; the solution was replenished to 1500 L and stirred for 20 minutes.

[0070] 2) Put 600 kg of catalyst carrier to be impregnated into the carrier barrel 4 (the input amount of the carrier is 2 / 3 of the volume of the carrier barrel). The carrier bucket is hoisted into the impregnation tank 2 by means of an electric hoist. Turn on the rotating motor to make the carrier barrel rotate. The number of revolutions of the carrier barrel is 10 revolutions / min.

[0071] 3) Turn on the delivery pump 31, pump the impregnating liquid in the impregnating liquid storage tank 1 into the impregna...

Abstract

The invention relates to the technical field of catalyst manufacturing, and discloses a catalyst impregnation device and an impregnation method using the same. The device comprises an impregnation liquid storage tank (1) used for preparing or containing impregnation liquid; an impregnation tank (2) for impregnating a catalyst carrier; a conveying pipe (3) used for conveying the impregnation liquid in the impregnation liquid storage tank (1) into the impregnation tank (2); a carrier tub (4) for accommodating a catalyst carrier to be impregnated; and a drive unit (5) for controlling the rotation and movement of the carrier tub (4). Automatic control over the whole impregnation process can be achieved, and it is guaranteed that impregnated catalyst finished product active components are evenly distributed.

Description

technical field [0001] The invention relates to the technical field of catalyst production, in particular to a catalyst impregnation device and an impregnation method using the device. Background technique [0002] In the field of catalyst manufacturing, when producing catalysts, the impregnation method is usually used to load the active components on the catalyst carrier. Impregnation is mainly divided into two methods: saturated impregnation and supersaturated impregnation. Saturated impregnation is impregnated with the amount of impregnating liquid that can be absorbed by the catalyst carrier. This impregnation method has a low loading of active components; The impregnation method lacks the control of the impregnation process, and the catalyst active components impregnated by this method are unevenly distributed, and the content of the active component loading fluctuates greatly. [0003] Therefore, there is an urgent need to provide a device and method that can well co...
