Porocel’s advanced moving belt technology combined with our optiCAT PlusSM stripping unit lowers cost, improves yield, and restores spent catalyst to its maximum potential.







The sophisticated control system of the moving belt process minimizes problems with channeling, hot spots and sintering. A thin bed of material is transported through multiple regeneration zones on a porous, stainless steel belt. Radiant tube burners heat the air and combustion gasses that flow through the catalyst bed. Multiple thermocouples in each zone monitor the bed temperatures as the carbon and sulfur contaminants are removed through controlled oxidation.

Recent improvements in our regeneration temperature control system virtually eliminate the risk of thermal damage to the catalyst and allow us to regenerate catalysts to their maximum possible activity.

Because of excellent temperature control, we avoid collapsing pores, which prevents surface area reduction and sintering. Several plows along the regeneration belts gently turn over the catalyst to ensure it regenerates evenly. This minimizes breakage and attrition, which is particularly important when regenerating eggshell-type precious metal catalyst. The improved stripping efficiency resulting from optiCAT Plus, reduces residence time on the belt regenerator, which increases throughput and product quality and results in a milder regeneration.

By combining optiCAT Plus with the moving belt process, we restore catalysts and adsorbents to their maximum potential with minimal breakage.
