Problems solved by technology

During the beating process, it is necessary to manually unpack, measure, and feed materials. The operating environment is relatively harsh, and the labor cost and power consumption are also high, which makes the problems of processing cost, environmental protection, and labor protection of workers very prominent.
[0006] There are many patents related to cracking catalysts, catalyst substrates and their preparation methods, but these patents mainly involve the modification of kaolin, the formulation of catalysts, operating parameters in the preparation process, additives, etc., and the continuous preparation process of kaolin colloids has not yet been reported.

Embodiment 1

[0027] This embodiment illustrates: adopt the implementation effect of the method provided by the present invention.

[0028] Select 100kg of kaolin raw soil (produced by Suzhou Kaolin Company) with a solid content of 77% by weight. To prepare a kaolin colloid with a solid content of 20% by weight, the amount of hydrochloric acid added is the final colloid PH=1.0.

[0029] The kaolin is sent to the crusher XY-7 at a constant speed by the single-screw conveyor ET-20-5. After continuous crushing, the kaolin becomes fine powder with an average particle size of 138um. During the crushing process, kaolin fine powder flows into the hopper of the metering system of the FY-02S humidifier by gravity. At the same time, turn on the metering pump to send the mixture of hydrochloric acid and chemical water into the humidifier, so that the humidifier starts to work. After 1 hour, the kaolin colloid was prepared, and the pH value, solid content and average particle size of the obtained coll...

Embodiment 2

[0032] This embodiment illustrates: adopt the implementation effect of the method provided by the present invention.

[0033] 100kg of raw kaolin soil (produced by Suzhou Kaolin Clay Company) was selected, the solid content was 77% by weight, the solid content of kaolin colloid was designed to be 20% by weight, and the amount of hydrochloric acid added was the final colloid PH=1.0.

[0034] The kaolin is fed into the crusher XY-7 at a constant speed by the single-screw conveyor ET-20-5. After continuous crushing, the kaolin becomes a fine powder with an average particle size of 132um. During the crushing process, the kaolin fine powder flows into the FY- The hopper of the metering system of the 02S humidifier. At the same time, turn on the metering pump to send the mixture of hydrochloric acid and chemical water into the humidifier. The humidifier starts to work to obtain kaolin colloid. After 40 minutes, the colloid is prepared and the colloid obtained is detected. The pH val...

Embodiment 3

[0037] This embodiment illustrates: adopt the implementation effect of the method provided by the present invention.

[0038] 100 kg of raw kaolin soil (produced by Suzhou Kaolin Clay Company) was selected, with a solid content of 77% by weight, a designed kaolin colloidal solid content of 40% by weight, and an amount of hydrochloric acid added to the final colloid PH=1.0.

[0039] The kaolin is sent to the crusher XY-7 at a constant speed by the single-screw conveyor ET-20-5. After continuous crushing, the kaolin becomes fine powder with an average particle size of 135um. During the crushing process, fine kaolin powder flows into the hopper of the metering system of the FY-02S humidifier by gravity, and at the same time, the metering pump is turned on to send the mixture of hydrochloric acid and chemical water into the humidifier, and the humidifier starts to work to obtain kaolin colloid After 1 hour, the colloid was prepared, and the pH value, solid content and average part...

Abstract

The invention discloses a kaolin colloid preparation method which including following steps: (1)Kaolin is transferred to preparation locale by container, than is inputted into the kaolin store jar; (2)Machine crash the kaolin in the store jar until the average diameter less than 150mum; (3) The kaolin powder after crashing is transferred to the next step by screw transport; (4) Blend the necessary liquid material for kaolin colloid and the kaolin powder, and prepare the kaolin colloid. This method can reach the continuum and automation of the preparation procession, and decrease the material consume and labor cost.

Description

technical field [0001] The invention relates to a preparation method of kaolin colloid in the preparation process of petrochemical catalysts. Background technique [0002] Catalytic cracking is an important petroleum processing process, and the catalyst used in this process is mainly composed of substrate and active components. The main functions of the matrix component are: disperse the active components, so that the active components can fully exert their catalytic effect; make the catalyst have a certain mechanical strength, especially wear resistance; effectively disperse heat, so that the active components will not be exposed to high temperature Rapid inactivation under certain conditions, prolonging the service life; having a certain ability to crack macromolecules, and having a certain effect on capturing harmful elements, etc. Therefore, the matrix part is an important part of the cracking catalyst, and its performance and manufacturing cost have an important impact...
