Hydrofining catalyst, its preparation and application thereof

A hydrofining catalyst comprising:

• an inorganic refractory component comprising a first hydrodesulfurization catalytically active component comprising a first metal element in a mixture with at least one oxide selected from the group consisting of alumina, silica, magnesia, calcium oxide, zirconia, and titania;
• a second hydrodesulfurization catalytically active component comprising a second metal element and is supported on the inorganic refractory component;
• and
• an organic component supported on the inorganic refractory component and comprising a carboxylic acid and optionally an alcohol,
• wherein the first metal element is selected from the group consisting of Group VIII metal elements and Group VIB metal elements, and the second metal element is a combination of at least a Group VIII metal element and at least a Group VIB metal element;
• and
• wherein the Group VIII metal element is selected from the group consisting of iron, cobalt, and nickel, and the Group VIB metal element is selected from the group consisting of chromium, molybdenum, and tungsten.
