Catalyst preparation system

Abstract

The invention discloses a catalyst preparation system. The catalyst preparation system comprises a carrier storage device, a solution storage device and a rotary drum, wherein the carrier storage device is used for storing a catalyst carrier; the solution storage device is used for storing a solution containing active components; the rotary drum is inclined; the carrier storage device and the solution storage device are respectively communicated with the rotary drum; the solution containing the active components is sprayed into the rotary drum from the solution storage device in an atomizing form; a material turning piece is arranged on the side wall of the rotary drum and is used for turning the catalyst carrier which enters the rotary drum from the carrier storage device during the rotation of the rotary drum. According to the catalyst preparation system provided by the invention, the rotary drum which is used for impregnating the catalyst carrier can be inclined. Therefore, the catalyst carrier can move from the charge end to the discharge end when being impregnated by the solution containing the active components, so that a catalyst can be continuously prepared; moreover, by arranging the material turning piece on the side wall of the rotary drum, the catalyst carrier can be turned by the material turning piece during the rotation of the rotary drum, so that the effective contact effect of the catalyst carrier and active substances is improved.

Description

technical field [0001] The invention relates to the field of catalyst preparation, in particular to a catalyst preparation system. Background technique [0002] In the catalyst preparation and production process, there are many production methods, such as impregnation method, roll coating method, precipitation method, mixing method, ion exchange method, gas phase synthesis method and so on. Among them, the impregnation method is a more commonly used method. In the impregnation method, the impregnation step of impregnating the active component in the active component solution onto the catalyst support is the most important step. [0003] In the prior art, the traditional equipment for realizing the above impregnation steps can refer to the impregnation tanks, impregnation baskets, impregnation mesh belts, impregnation drums, impregnation drums, etc. Impregnation rolling ball machine, impregnation fluidized bed, etc. However, although these impregnation equipment can accomp...

AI Technical Summary

Problems solved by technology

However, although these impregnation equipment can accomplish the purpose of impregnating the active material on the catalyst, there are many problems in these impregnation equipment and devices, such as intermittent operation, inability to realize continuous production, unstable product quality, and small processing capacity Shortcomings, catalyst support structure damage and other problems

[0004] In addition, many diffusion-limited catalytic reactions and highly exothermic catalytic reactions require heterogeneous catalysts to meet the requirements of the reaction process. Traditional production equipment can no longer meet the requirements of producing heterogeneous catalysts.
