How to use nickel catalyst reasonably
Classification:
【Summary】The deactivation of the nickel-based catalyst is greatly related to the conditions of its use. Excellent catalytic performance is the basis for the use of nickel-based catalysts, and good conditions of use are the guarantee of the quality of nickel-based catalysts. Today we will share with you how to use nickel catalysts reasonably.
The deactivation of the nickel-based catalyst is greatly related to the conditions of its use. Excellent catalytic performance is the basis for the use of nickel-based catalysts, and good conditions of use are the guarantee of the quality of nickel-based catalysts. Today we will share with you how to use nickel catalysts reasonably.
Some people have systematically tracked and analyzed the samples of methanol synthesis nickel catalysts and carbon monoxide high temperature shift nickel catalysts from large, medium and small plants in different regions in China, and concluded that the deactivation of nickel catalysts is mostly caused by improper process and operation, and the deactivation caused by poor quality of nickel catalysts is very little.
There are many examples in industrial production practice. A certain type of nickel-based catalyst is used well in some factories, but it fails in others. Here, there is a problem of rational use of the nickel-based catalyst.
The rational use of nickel-based catalysts is more complex, in fact, this is a practical and empirical discipline, but also a marginal science.
It involves the development and development of nickel catalysts, the selection of nickel catalyst production process, the design of nickel catalyst reactor, the implementation of catalytic process and the use of a variety of equipment and nickel catalyst operation. Often there is a problem in a certain link, which may affect the normal function of nickel-based catalysts in industrial production.
In some foreign countries, the development and research of nickel-based catalysts (including basic research), research and improvement of nickel-based catalyst production process, research and design of nickel-based catalyst reactors, research on the conditions of use of nickel-based catalysts, and after-sales technical services of nickel-based catalysts form a chain system, with both division of labor and collaboration among various links.
However, the technical strength of China's nickel-based catalyst industry is not very reasonable. Most of the development and research work of nickel catalysts are concentrated in various colleges and universities and research institutes, but they are not familiar with the current production process of nickel catalysts in China and the various use processes of nickel catalysts in industry.
Nickel catalyst manufacturers purchase the new nickel catalyst preparation process developed from the research unit for production, and are also responsible for the after-sales service of nickel catalyst products, but they do not have a deep understanding of the background and performance of product development, nor can they use the feedback information for product performance improvement.
The development and design of nickel-based catalyst reactors are often independent of the nickel-based catalyst production system. Therefore, in catalytic engineering, there is no lack of nickel-based catalysts and catalytic processes and reactors do not match the phenomenon, so that nickel-based catalysts can not play their intrinsic activity or even prematurely end their service life, which not only affects the economic benefits of nickel-based catalyst users, but also causes a waste of social resources.
