“…Compared to spent catalysts, the catalytic performance of reactivated catalysts is significantly enhanced, and the light oil production is greater than that of new catalysts. Istadi, et al [29] In an additional investigation, the reactivation & modifying of the spent RFCC catalyst with sulfuric acid (96.1%) and citric acid (99%) as acids treatment was tested by altering the acid solution concentrations bat 80 o C under stirring for three hours with a solid Xbox liquid ratio of (1:10) w/v [34] . This research indicates that sulfuric acid treatment is better to citric acid treatment for the removal of heavy metals from acid-affected catalysts.…”

Throughout refinement, catalysts are switched off in commercial catalytic processes. When they are not tuned, catalysts become dangerous. Deactivation catalyst is mostly wasted FCC catalyst as a result of heavy metal coke, poison, and sintering. Regenerating a deactivated catalyst could eliminate the metals while resurrecting the very desirable catalytic activity. While there are a few a variety of physical, chemical, and thermal treatment methods for removing metals, it is still difficult to discover reliable, effective, and cost-effective regeneration strategies for catalytic processes in commercial application. In addition, the effect of relevant reaction parameters on the route for regenerating utilized catalyst was investigated, and suggestions were made for the future of this research. This brief review offers an important evaluation of the material recently made publicly available on the reuse of used FCC catalyst by oxidation, gasification, and chemical processes, could potentially provide some insight into the development and improvement of catalysts as well as associated processes.
