Continuous production apparatus and method of catalysts

Abstract

The invention relates to a continuous production apparatus and method of catalysts. The apparatus comprises a preparing tank for preparing a solution, a soaking tank for soaking a catalyst, jackets arranged in the preparing tank and the soaking tank respectively, and a heating device for heating media in the jackets; a stirring device is arranged in the preparing tank; a medium outlet of the jacket of the preparing tank is connected with a medium inlet of the soaking tank via a pipeline; a medium inlet of the preparing tank is connected with a medium outlet of the soaking tank via a pipeline; each pipeline is provided with a pump and a valve; the medium in the jacket of the preparing tank and the medium in the jacket of the soaking tank can be circulated; the medium in the jacket of the preparing tank can also be subjected to single circulation.

Description

technical field [0001] The invention relates to a catalyst continuous production equipment and method. Background technique [0002] The impregnation method is a method of manufacturing catalysts with impregnation as the key step, and it is also a method widely used in catalyst production at present. The impregnation method usually impregnates various types of carriers in a liquid containing active substances. After the impregnation is balanced, remove the remaining liquid, and then perform drying, roasting, activation and other processes to prepare the catalyst. [0003] For a single catalyst impregnation device, it takes too long to prepare the solution in the early stage, including: 1. Using an electric heating rod to heat the medium in the jacket of the impregnation tank to the expected temperature by convective heat transfer is too long, and the solution in the impregnation tank dissolves and absorbs heat. There is a large temperature difference of 10-20°C in the upper...

Problems solved by technology

[0003] For a single catalyst impregnation device, the time for preparing the solution in the early stage is too long, including: 1. Use an electric heating rod to heat the medium in the jacket of the impregnation tank to the expected temperature by The convective heat transfer time is too long, and the solution in the dipping tank dissolves and absorbs heat, and there is a large temperature difference of 10-20°C between the upper and lower parts of the dipping tank, which makes the whole device unable to quickly reach the expected temperature; 2. The heating device in the jacket is partially overheated, and the heating element Easy to damage; 3. The material in the jacket cannot be circulated, and there is a large temperature difference between the upper and lower sides, which makes the impregnated material heated unevenly and affects the production quality
