Abstract

See full text

A process that provides for the improvement of the properties of a distillate feedstock that has significant concentrations of nitrogen and polyaromatic compounds. The process includes a first reaction zone that uses a base metal catalyst and is operated under high pressure conditions to provide for the hydrodenitrogenation of organic nitrogen and saturation of polyaromatic compounds contained in the distillate feedstock. The first reaction zone treated effluent is separated into a heavy fraction and a lighter fraction with the heavy fraction being charged to a second reaction zone that also uses a base metal catalyst and is operated under high pressure conditions to provide for the saturation of monaromatic compounds that are contained in the heavy fraction. The inventive process provides for a high quality, low-sulfur and low-nitrogen diesel product that has a significantly lower aromatics content than the distillate feedstock and having a high value for its high Cetane Index.
