چکیده انگلیسی
In this study, three hydrotalcite-based De-SOx catalysts were prepared using different approaches: impregnation, coprecipitation, and precipitation using the separate nucleation and aging steps (SNAS) method. The physicochemical properties of these catalysts were studied and their SOx removal behaviors were characterized with a custom-built apparatus simulating the conditions in a fluid catalytic cracking (FCC) regenerator. The results showed that the catalyst prepared using the SNAS method had the highest SOx adsorption rate, the largest SOx pick-up capacity (1.31Â g/g cat.) and the lowest onset reduction temperature (805Â K), which makes it an excellent De-SOx catalyst with promising applications in industry.
