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.
Claims10
A hydrotreating catalyst comprising molybdenum (Mo), a phosphorus compound, sulfur and at least one metal selected from the group consisting of iron, cobalt and nickel, 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, and wherein the molybdenum is contained in an amount of 6 to 15% by weight in terms of oxide, based on the weight of the catalyst.
