Choose ceramic balls
Follow the 2X rule to choose the ceramic balls and filling. The diameter of the ceramic balls should be double of the supported materials (Catalyst/Adsorbent/or other media).
For examples, for 1.6mm(1/16") diameter catalyst, the first layer ceramic balls diameter should be 3mm(1/8"); the second layer ceramic balls diameter should be 6mm(1/4"). Fill more layers of ceramic balls should follow 2X rule. Recommend the filling height for each layer should no less than 100mm(4").
Filling ceramic balls
Before fill the ceramic balls, firstly should check the reactor, remove the irrelevant materials. Check the grid, distributor, outlet collector etc, secure install correctly and keep film. Check the sieves, and repair the gaps at joint and broken holes. At the same time, remove the particles and powder which wedge on the girds and sieves, to avoid generating the abnormal pressure drop, and the gas channeling flow. Ceramic balls should be dropped free fall and less than 2 cubic feet height. On the continuous filling ceramic balls, the ceramic balls should be put leval and uniform distribution. During the filling ceramic balls, the physical carrying should be minimized.
