【Q&A Question 118】August 16, 2016: What is the role of additives in hydrogenation catalysts? The answer key will be available after responding; scoring is based on addressing the key points. To improve certain aspects of the catalyst’s performance, such as activity, selectivity, stability, etc.
There are many types of additives, whose main functions are as follows: 1. To enhance the activity and stability of the catalyst and to suppress deactivation. 2. Improve the adsorption and desorption properties of the catalyst. 3. The amount of additives used is low, and multiple types can be added.
Additives can alter the electronic properties and catalytic selectivity of the active components in the catalyst, as well as stabilize its structure and promote the formation of intermediates
It improved the dispersion and reduction capacity of nickel species in the catalyst, thereby enhancing the catalyst’s reaction performance
Role of additives in hydrogenation catalysts: improving selectivity and extending catalyst life
Increase the heat resistance and strength of the catalyst
Reduce catalyst coking and extend catalyst lifespan
To improve certain aspects of the catalyst’s performance, such as activity, selectivity, stability, etc.
:1 Improve the activity and stability of the catalyst, and suppress deactivation. 2. Improve the adsorption and desorption properties of the catalyst. 3. The amount of additives used is low, and multiple types can be added.
