Alumina support compositions comprising at least 0.1 wt % of silica are disclosed. The alumina support are characterized by a pore volume of greater than 0.60 cc/g, a median pore size ranging from about 70 to about 120, a pore size distribution such that at least 90% of the total pore volume falls within the range of about 20 to about 250, and a pore size distribution width of no less than about 40. Alumina compositions of the present invention exhibit a primary peak mode at a pore diameter less than the median pore diameter. Also provided are catalysts made from the alumina supports, and processes of preparing and using the supports and catalysts.

This disclosure relates to supported multi-metallic catalysts for use in the hydrotreating of hydrocarbon feeds, as well as a method for preparing such catalysts. The catalysts are prepared from a catalyst precursor comprised of at least one Group VIB metal, at least one Group VIII metal and an organic acid. The catalyst precursor is thermally treated to partially decompose the organic acid, then sulfided. The catalysts have a high carbon-as-carboxyl to total carbon ratio (C/C) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst.

The catalysts have a high carbon-as-carboxyl to total carbon ratio (C/C) as a result of a unique post-metal calcination method employed during the manufacture of the catalyst. As a result, the hydrotreating catalysts have lower percent weight loss-on-ignition, higher activity and longer catalyst life.

A chelated hydroprocessing catalyst exhibiting low moisture is obtained by heating an impregnated, calcined carrier to a temperature higher than 200&#xb0; C. and less than a temperature and for a period of time that would cause substantial decomposition of the chelating agent.
