Catalyst for Hydrotreating Heavy Hydrocarbon Oil, Method for Producing Same, and Method for Hydrotreating Heavy Hydrocarbon Oil

Abstract

[Problem] To provide a catalyst for hydrotreating a heavy hydrocarbon oil, the catalyst exhibiting excellent demetallization performance, desulfurization performance, and deasphaltene performance and having high strength. [Solution] A hydrotreating catalyst, which is a catalyst for hydrotreating a heavy hydrocarbon oil, the catalyst including an alumina-phosphorus oxide carrier, and a hydrogenation-active metal component supported on the carrier, in which the content of phosphorus in the carrier is 0.4 to 2.0 mass % in terms of P2O5, the carrier has a local maximum value of the differential pore volume distribution in a pore diameter range of 18 to 22 nm measured by mercury intrusion porosimetry, in the carrier, the ratio (ΔPV/PVT) of a volume (ΔPV) of pores having a pore diameter in a range deviating from a range of a pore diameter at the local maximum value±2 nm to the total pore volume (PVT) measured by mercury intrusion porosimetry is 0.50 or less, and the crystalline form of a portion of alumina in the alumina-phosphorus oxide carrier is γ-alumina.
