The present invention relates to a catalyst having at least one peak in each of a range of a pore diameter of 0.45 μm to 10.0 μm and a range of a pore diameter of 0.040 μm to 0.45 μm in a pore distribution (−dV/d (log D) vs D) measured by mercury porosimetry, in which when a maximum value of −dV/d (log D) in the range of the pore diameter of 0.45 μm to 10.0 μm is represented by A and a maximum value of −dV/d (log D) in the range of the pore diameter of 0.040 μm to 0.45 μm is represented by B, (B/A) is 0.20 to 13.0 (V represents a volume (unit: mL/g) of filled mercury per sample weight, D represents the pore diameter (unit: μm), log D represents a natural logarithm of D, and −dV/d (log D) represents a reciprocal of a value obtained by differentiating a cumulative pore volume in a specific pore diameter range by a logarithm of the pore diameter).
A catalyst having at least one peak in a range of a pore diameter of 0.45 μm to 10.0 μm and at least one peak in a range of a pore diameter of 0.040 μm to 0.45 μm in a pore distribution (−dV/d (log D) vs D) measured by mercury porosimetry, wherein
