I want to use Ru-al2o3-Zeolite catalyst in pellet form to perform the reaction in the flow reactor. Please suggest me ideal pressure to pelletize it and the ideal size of the pellet.
The particle size affects strongly influences the stability of the catalyst.The gas selectivity declines slowly for the 40–60 and 60–100 μm catalysts.
What is the flow reactor design? If I assume it is a section of cylindrical tube with some means of catalyst grid or other support, then the size of the pellets relative to the flow reactor diameter should be considered. If there are less than ~10 pellet diameters (for cylindrical pellets calculate the equivalent diameter, d(eq)) across the reactor diameter, then there can be wall effects that impact gas flow through the catalyst bed and so the apparent performance of the catalyst. I suggest finding a text that describes this in more detail as I'm working from memory!
Peter Broadhurst It down flows cylindrical reactor with half-inch (ID) and 26-inch length.
