Abstract: 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.

Abstract: Processes and apparatuses for isomerizing hydrocarbons are provided. In an embodiment, a process for isomerizing hydrocarbons includes providing a first hydrocarbon feed that includes hydrocarbons having from 5 to 7 carbon atoms. The first hydrocarbon feed is fractionated to produce a first separated stream that includes hydrocarbons having from 5 to 6 carbon atoms and a second separated stream that includes hydrocarbons having 7 carbon atoms. The first separated stream is contacted with a benzene saturation catalyst at benzene saturation conditions to produce an intermediate stream and subsequently isomerized in the presence of a first isomerization catalyst and hydrogen under first isomerization conditions to produce a first isomerized stream. The second separated stream is isomerized in the presence of a second isomerization catalyst and hydrogen under second isomerization conditions that are different from the first isomerization conditions to produce a second isomerized stream.

Abstract: Methods are provided for hydrotreating a feed to generate a product with a reduced or minimized aromatics content and/or an increased distillate product yield. A distillate boiling range feed having an elevated content of sulfur and/or nitrogen can be hydrotreated using at least two hydrotreating stages with intermediate separation to produce a hydrotreated distillate boiling range product with a reduced or minimized aromatics content. Additionally or alternately, a mixed metal catalyst formed from a suitable precursor can be used during the hydrotreating. A mixed metal catalyst formed from a suitable precursor can provide an unexpectedly superior activity for aromatic saturation. A still further unexpected benefic can be achieved by combining a multi-stage hydrotreating process with intermediate separation with hydrotreating in the presence of a mixed metal catalyst formed from a suitable precursor.
