| abstract |
The present invention provides a manufacturing method, including: a step for adding at least one material selected from alumina components and clay minerals to a binder containing a silicon oxide, and obtaining a mixed slurry; a step for mixing the mixed slurry and a first metal component compound, heating the metal component mixed slurry, and obtaining a metal scavenger precursor; and a step for drying, and further firing, the metal scavenger precursor to obtain a metal scavenger. The present invention also provides a metal scavenger comprising a binder mainly containing a silicon oxide, one or two materials selected from alumina components and clay minerals, and an oxide of a first metal component, the metal scavenger being such that a peak of a silicate of the first metal component is not detected in X-ray diffraction analysis, and the wear resistance index CAI is within a prescribed range. The present invention also provides a fluid catalytic cracking catalyst containing the metal scavenger, a zeolite component, a binder component, and a clay mineral component. |
