Rapid Regeneration of Spent FCC Catalysts through Selective Bioleaching by the Spent Medium Process.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fluid catalytic cracking (FCC) catalysts play an important role in modern industrial production and are capable of converting heavy oils into light oils. However, in the process of long-term use, the FCC catalyst will reduce its activity due to internal wear and external factors, and it will become a spent catalyst after failing to meet the requirements of use. Approximately one million tons of spent FCC catalysts are generated annually, and improper disposal of this hazardous waste can pose significant harm. In this study, the spent catalyst is treated by the bioleaching method, which restored its activity to some extent, allowing for its reuse in industrial production. This study found that at 58 °C, the biological cleaning of spent catalyst with 5.6% pulp density can increase its activity by about 10%, whereas the corresponding treatment with a mixed acid only achieved a 2% increase. This demonstrates the feasibility of the bioleaching method and provides insights into further enhancing the activity of spent catalysts.
