PROBLEM TO BE SOLVED: To provide a method that measures a content of an FCC catalyst included in an FCC slurry oil in a shorter time than that of a measuring method using a conventional inductive coupling plasma emission spectral analysis method.SOLUTION: A measuring method of an FCC (Fluid Catalytic Cracking) catalyst content in an FCC slurry oil, includes: a centrifugal separation process in which a mixture of an FCC slurry oil and an organic solvent is subjected to centrifugal separation treatment by the number of rotation in which a relative centrifugal force becomes at least 400×g; a heating process in which an accumulation obtained by the centrifugal separation process is heated at 500-1,000°C to remove an oil content; and a weighing process in which a residual material after heating of the accumulation is weighed after the heating process. |
