Smaller honeycomb channels increase surface area but generally increase gas-flow resistance and plugging sensitivity. Larger channels reduce pressure drop and improve fouling tolerance. RTO selection must balance heat transfer, fan power and contamination risk.

Higher honeycomb ceramic CPSI increases geometric surface area but usually reduces channel size and fouling tolerance. Select cell density by balancing heat transfer or catalyst area against pressure drop, dust loading and plugging risk.

Review ceramic support-ball orders layer by layer. Confirm reactor diameter, ball size, layer thickness, catalyst interface, support-grid opening, ceramic grade and quantity for each grade before converting the loading schedule into total weight.

Inert ceramic support balls can often be reused during catalyst changeout if each graded layer remains mechanically sound, chemically stable, clean and correctly sized. Keep layers separated during unloading and base reuse on inspection rather than age alone.

Broken ceramic support balls create smaller fragments that reduce void space, increase pressure drop, allow bed settlement and promote catalyst migration. Investigate the cause before simply replacing damaged media.
