A production method comprises the steps of obtaining a mixed slurry by adding an alumina component and at least one selected from an alumina component and a clay mineral to a binder containing a silicon oxide; obtaining a metal trapping precursor by mixing the mixed slurry with a compound of a first metal component and heating the mixed slurry of metal component; and obtaining a metal trapping by drying and calcining the metal trapping precursor. A metal trapping comprises: a binder mainly containing silicon oxide, one or two selected from an alumina component and a clay mineral, and an oxide of a first metal component; having no peak of silicate of the first metal component detected in X-ray diffraction analysis, having an attrition resistance index CAI within a predetermined range. A fluid catalytic cracking catalyst comprises the metal trapping, a zeolite component, a binder component, and a clay mineral component.

Metal trapping, method for manufacturing metal trapping, and fluid catalytic cracking catalyst

A fluid catalytic cracking catalyst for hydrocarbon oil that is a blend of two types of fluid catalytic cracking catalysts each of which has a different hydrogen transfer reaction activity or has a pore distribution within a specific range after being pseudo-equilibrated. One catalyst is a catalyst containing a zeolite and matrix components, and the other catalyst is a catalyst containing a zeolite and matrix components. This catalyst is composed of the one catalyst and the other catalyst blended at a mass ratio within a range of 10:90 to 90:10.
