Type II hydrotreating catalyst for hydrocarbon oil and method for hydrotreating hydrocarbon oil

A hydrotreating catalyst for hydrotreating middle distillates having a nominal boiling range of about 160-400° C., the hydrotreating catalyst comprising:

• one or more hydrotreating metal components and a chelating agent carried on a support, said support comprising an inorganic oxide binder and a post-framework modified ultra-stable Y (USY) zeolite in which a portion of aluminum atoms constituting a zeolite framework thereof is substituted with zirconium atoms and/or titanium atoms and/or hafnium atoms,
• wherein the one or more hydrotreating metal components form a metal complex via the chelating agent, and are carried on said support as chelating complex type II active sites,
• wherein carbon including carbon content from the chelating agent is present in an amount of at least about 2 weight % of a total mass of said hydrotreating catalyst,
• wherein mass loss of the hydrotreating catalyst resulting from heat treatment for 2 hours at 570° C. in atmospheric conditions is greater than about 10 weight % of the total mass of said hydrotreating catalyst prior to the heat treatment;
• and
• wherein the hydrotreating catalyst is sulfided and wherein an amount of nitric oxide adsorption after sulfiding is more than about 10.0 milliliters per gram.
