Petrochemical reformers are crucial units that convert low-octane naphtha into high-octane gasoline components and valuable aromatics. The catalysts employed in these reformers, often based on platinum and rhenium, are highly sensitive to impurities present in the feed. Among these impurities, arsenic is particularly detrimental, acting as a severe poison for these precious metal catalysts.

Arsenic compounds can bind strongly to the active sites of reformer catalysts, blocking catalytic reactions and leading to a rapid decline in performance. This deactivation not only reduces the efficiency of the reforming process but also necessitates premature catalyst regeneration or replacement, incurring significant costs and downtime. Therefore, effective removal of arsenic from the feed stream before it enters the reformer unit is of paramount importance.

This is where dearsenic agents play a critical role. These specialized purification agents are designed to selectively adsorb or react with arsenic species, preventing them from reaching and poisoning the reformer catalysts. An ideal dearsenic agent possesses a high capacity for arsenic removal and maintains its structural integrity and activity under the operating conditions of pre-treatment units. Features such as strong arsenic removal ability and high compressive strength are indicative of a robust and effective agent.

Ningbo Inno Pharmchem Co., Ltd. offers high-performance dearsenic agents that are essential for safeguarding the investment in costly reformer catalysts. By ensuring that feedstocks are free from arsenic contamination, refiners can maximize catalyst lifespan, maintain optimal process efficiency, and ensure consistent production of high-quality reformate.
