| 摘 要： | A novel Micro-Reactor-GC system was used to study the performance of two kinds of FCC catalysts coked in a FFB reactor under simulated industrial conditions using dodecane and octene as probe molecules. The result shows that the performance of the two cokedcatalysts differed significantly. The ^129Xe NMR technique was used to detect the location of coke deposition on the catalysts, which gave a good explanation of the experimental results.
