Abstract
Abstract A process for hydrotreating a hydrocarbon stream such as petroleum distillate and similar hydrocarbon materials by contacting said stream with hydrogen and a catalyst comprising a porous refractory inorganic oxide support and deposited thereon hydrogenation components comprising chromium, molybdenum and at least one Group VIII metal. This process enables improved removal of nitrogen and sulfur, particularly from gas oils.
