Abstract
A hydrotreating catalyst comprising a Group 8 metal of the periodic table, molybdenum (Mo), phosphorus and sulfur, wherein the average coordination number [N(Mo)] of the molybdenum atoms around the molybdenum atom is from 1.5 to 2.5 and the average coordination number [N(S)] of the sulfur atoms around the molybdenum atom is from 3.5 to 5.0 when MoS2 structure in the catalyst is measured in accordance with extended X-ray absorption fine structure (EXAFS) analysis.
