What is the relationship between the particle size of amorphous ammonia synthesis catalysts? The catalyst particles are small in size and have a relatively uniform size distribution
The particle size of the catalyst should be as small as possible. However, for the industrial use of catalysts, such requirements cannot be unlimited. Because the smaller the particle size of the catalyst, the greater the bed resistance generated. When loading the catalyst into an axial tower, appropriate amounts of larger-particle catalyst should be placed at the bottom and top of the tower.
Particle size is inversely proportional to dimension.
