Process and catalyst for the hydroconversion of a heavy hydrocarbon feedstock

Abstract From the Canadian patent

A method of hydroprocessing a heavy hydrocarbon feedstock using a hydroprocessing catalyst having specific properties making it effective in the hydroconversion of at least a portion of the heavy hydrocarbon feedstock to lighter hydrocarbons. The hydroprocessing catalyst comprises a Group VIB metal component (e.g. Cr, Mo, and W), a Group VIII metal component (e.g. Ni and Co) and, optionally, a potassium metal component that are supported on a support material comprising alumina. The alumina has novel physical properties that, in combination with the catalytic components provide for the , hydroprocessing catalyst. The hydroprocessing catalyst is particularly effective in the …
