Solid particle catalyst impregnation device and impregnation method

Abstract

The invention discloses a solid particle catalyst impregnation device and a solid particle catalyst impregnation method. The device comprises a base. A column extends upward from a first end of the base. The device comprises a rotation main machine which is obliquely fixed on the column. The device comprises a rotation bottle with an opening connected to one side of the rotation main machine. The device comprises a two-way pipe with an upper opening and a lower opening; the lower opening is connected on the other side of the rotation main machine; an inner tube extends from the upper opening to the inside of the two-way pipe, and extends all the way into the rotation bottle through the rotation main machine. The device comprises a feeding bottle with an upper-end opening and a lower-end opening, wherein the lower-end opening is connected to the upper opening of the two-way pipe. The device comprises a vacuum pump communicating with the inside of the rotation bottle through a pipeline. The device also comprises a heating device arranged below the rotation bottle. The device is suitable for impregnation processes of small batches of catalysts, and assists in improving catalyst active component dispersion uniformity.

Description

technical field [0001] The invention relates to a catalyst impregnation device and impregnation method, in particular to a solid particle catalyst impregnation device and impregnation method with pores. Background technique [0002] Solid particle catalysts are widely used in petroleum, chemical, pharmaceutical and other fields due to their certain mechanical strength. Solid particulate catalysts generally consist of a carrier and an active metal component. The dispersibility of the active metals in the inner pores and surfaces of the carrier largely determines the catalyst's performance such as activity and selectivity. [0003] At present, there is no solid particle catalyst impregnation device suitable for small batch production in the prior art. In order to fully contact the impregnating solution and the solid particle material, the impregnating device needs to be shaken manually; if the amount of impregnating liquid is too small, it is easy to cause part of the surfac...

AI Technical Summary

Problems solved by technology

In order to fully contact the impregnating solution and the solid particle material, the impregnating device needs to be shaken manually; if the amount of impregnating liquid is too small, it is easy to cause part of the surface of the carrier not to be in contact with the impregnating liquid, resulting in uneven dispersion of the active metal components; if the amount of impregnating liquid is too large Too much, it is easy to cause solution accumulation, the carrier is prone to mutual adhesion during the drying process after impregnation, and the active metal component is partially lost

Especially for noble metal catalysts with a small amount of metal, the dispersion of noble metals generally does not exceed 50% in the catalysts prepared by the existing technology, so that the active metals are not fully utilized and affect the performance of the catalyst
