METHOD OF PRODUCING REGENERATED HYDROTREATING CATALYST AND METHOD OF PRODUCING PETROLEUM PRODUCTS

Document Type and Number:

WIPO Patent Application WO/2012/053299

Kind Code:

A1

Abstract:

A method of producing a regenerated hydrotreating catalyst comprises: a first step of preparing a hydrotreating catalyst that has been used in the hydrotreatment of distilled petroleum residue and comprises a metal element selected from group 6 elements of the periodic table; a second step of performing regeneration on a portion of the catalyst prepared in the first step, then performing x-ray microstructural analysis on the regenerated catalyst, and determining regeneration conditions wherein the ratio (Is/Io) between the peak strength (Is) of the peak pertaining to the bond between the metal element and a sulfur atom, and the peak strength (Io) of the peak pertaining to the bond between the metal element and an oxygen atom, in the radial distribution curve obtained from an extended x-ray absorption fine structure spectrum, is 0.10~0.3; and a third step of performing regeneration for the other portion of the catalyst prepared in the first step under the conditions determined according to the second step.
