Production process of VOCs waste gas treatment catalyst

Volatile organic compounds (VOCs) waste gas treatment catalyst is an important technology in the field of environmental protection, and its production process is complex and technical requirements are high. The main steps used in the production process of VOCs waste gas treatment catalyst:
1. Raw material preparation
To produce efficient VOCs catalytic oxidation catalysts, it is first necessary to select high-quality catalytic materials, including precious metal precursors, catalyst carriers (such as alumina, silicon oxide, etc.) and other auxiliary additives. These materials need to undergo strict quality inspections to ensure their purity and activity.
2. Catalyst carrier preparation
The preparation of catalyst carriers is the basis of the entire production process. Common carrier preparation methods include sol-gel method, impregnation method and co-precipitation method. Carriers prepared by these methods usually have high specific surface area and good pore structure to provide more active sites.
3. Introduction of active components
Introducing precious metals or other active components onto the carrier is one of the key steps. Generally, impregnation or ion exchange method is used to evenly distribute the active components on the surface of the carrier. Subsequently, drying and calcination are carried out to fix the active components and enhance their catalytic performance.
4. Catalyst molding
In order to facilitate practical application, the catalyst needs to be made into a certain shape, such as particles, strips or honeycombs. Common molding methods include extrusion molding and tablet molding. The molded catalyst needs to be further dried and sintered to improve its mechanical strength and stability.
5. Activity evaluation and quality control
The produced catalyst needs to undergo strict activity evaluation and quality control tests. Common test items include specific surface area, pore size distribution, mechanical strength, and VOCs removal efficiency. Through these tests, the high efficiency and stability of the catalyst in practical applications are ensured.
6. Packaging and storage
The catalysts that have passed the test will be packaged, usually with moisture-proof and anti-oxidation packaging materials to ensure the stability of their quality during storage and transportation. According to the needs of different customers, we provide a variety of packaging forms.
