Application of rotary vane vacuum pump in chemical catalysis industry
Adsorption and desorption tests are commonly used in chemical catalytic characterization, which generally need to be analyzed in a high vacuum environment. Rotary vane vacuum pump is widely used in chemical catalysis industry.
Catalytic chemistry has a profound influence on the development and progress of human society. More than 80% of the traditional chemical processes are related to catalytic action. In recent years, the role and status of catalytic chemistry have been further evaluated with the attention of human beings to energy, environment and health. Therefore, it is necessary to master some knowledge about catalysts and catalytic processes.
Chemical adsorption apparatus is an important instrument for dynamic temperature programmed research, it can be the catalyst for TPD, TPO, TPR, TPS, TPSR research, in order to the product of the generated in the process of temperature programmed a detailed qualitative quantitative analysis (i.e., in order to distinguish and detect the kinds of escaping gas), often need and online mass spectrometry. Tpd-ms, as a new on-line analytical method, can be used in the analysis of the components and contents of desorption efflorescent gases. Punnock rotary vane vacuum pump has been widely used in the field of chemical catalysis.
Rotary vacuum pump research and development, production and provide perfect vacuum system solutions, has been serving the world's top 500 enterprises and well-known Chinese universities and laboratories, products sold throughout the country, is currently China's application in the aerospace field, pharmaceutical, medical, nuclear industry leading brand.
