Production manner of the catalytic converter for regeneration hydrogen treating and the production mannered null metal of group 6 of the periodic table of the elements

摘要

PROBLEM TO BE SOLVED: To provide a method for easily manufacturing a regenerated hydrotreatment catalyst having satisfactory activity and a method for producing a petroleum product by using the regenerated hydrotreatment catalyst obtained by the manufacturing method.;SOLUTION: The used hydrotreatment catalyst comprising at least one metal selected from the group consisting of group 6 metals and metals of group 8 to group 10 in the periodic table is regenerated. The regenerated catalyst is subjected to an X-ray diffraction analysis and/or an X-ray photoelectron spectroscopic analysis of metal pieces to judge whether the regenerated catalyst is to be recovered. The regenerated catalyst judged to be recovered is recovered and distillates are hydrotreated by using the recovered catalyst.;COPYRIGHT: (C)2009,JPO&INPIT
