Technology for regenerating HDS naphtha catalysts from coker units used as silicon traps.

• Reduction of silicon by 82% in samples, as well as improved catalyst reactivity.
• Increases catalyst lifespan by 1.5–5 years.
• Reduces the frequency of catalyst loading and unloading operations, with economic impact.
• Decreases solid waste production, including hazardous waste, by 70%.
• Achieves operational performance above the industry average in hydrocarbon processing.
• Allows the technology to be used at least three times on the same catalyst.
• Management of contaminants in the coker naphtha stream.
• Full recovery of the capacity to retain silicon compounds.
• Recovery of HDS and HDN levels.
•
