Eurecat's SAS (Sample, Analyze, and Segregate) service provides a comprehensive approach for rejuvenating spent catalysts by identifying and segregating high-quality materials for regeneration. The process involves detailed analysis of contaminant profiles, ensuring that only catalysts with high activity are reused, thus maximizing efficiency and minimizing waste. Successful case studies demonstrate the potential for restoring catalyst performance to 'like-fresh' levels, benefiting refiners economically.

With SAS, numerous samples of spent catalyst are carefully analyzed for contaminant metals, carbon and sulfur content, and surface area. From this data, a contamination profile (Figure 1) can be developed. With such a profile, the process of segregating the material is straight- forward. The analysis showed that about one half of the catalyst in the Top Bed from the Lead Reactor and all of the Lag Reactor Top Bed contained clean catalyst that was suitable for regeneration. Unfortunately, since both Top Beds were vacuumed out, the particle length was much too short for regeneration and therefore all of the Figure 1Arsenic, Iron, and Silicon Profile material had to be discarded. The Bottom Beds were both successfully rejuvenated, recovering 500K pounds of catalyst with virtually the same activity as fresh ULSD Once the portion of the catalyst you want back catalyst.
