Abstract: A process for hydroprocessing a distillate stream to produce a stream exceptionally low in sulfur, with total aromatics and polynuclear aromatics being moderately reduced. A distillate stream is hydrodesulfurized in a first hydrodesulfurization stage. The product stream thereof is passed to a first separation stage wherein a vapor phase product stream and a liquid product stream are produced. The liquid phase product stream is passed to a second hydrodesulfurization stage and the product stream thereof is passed to a second separation stage wherein a vapor phase product stream and a liquid product stream low in sulfur are produced. At least a portion of the vapor product stream from said second separation stage can be cascaded to the first hydrodesulfurization stage.

Abstract: Disclosed is a method for treating naphtha. The method comprises providing naphtha feed, and the naphtha feed comprises naphthene ring-containing compounds. The naphtha feed is contacted with a ring opening catalyst containing a Group VIII metal under conditions effective to ring open the naphthene rings to form a ring opened product. The ring open product can then be contacted with a catalytic cracking catalyst under effective cracking conditions to form an olefin product. The olefin product will be particularly high in ethylene and propylene content.

CPC classification number: C10G45/02
Abstract: A process for producing distillate fuels, such as diesel fuels and jet fuels, having both high lubricity and low sulfur levels. Such fuels are produced by fractionating a distillate feedstream (10) into a light fraction (12) which is relatively low in lubricity and which contains from about 50 to 100 wpm of sulfur and a heavy fraction (14) having a relatively high lubricity. The first fraction (12) is hydrotreated to remove substantially all of the sulfur (16) and is then blended with the second fraction (14) to produce a distillate fuel product (18) having relatively low sulfur levels and a relatively high lubricity.

Abstract: A process for producing distillate boiling range streams that are low in both sulfur and aromatics. A distillate feedstock is treated in a first hydrodesulfurization stage in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst, thereby resulting in partial desulfurization of the stream. The partially desulfurized distillate stream is then treated in a second hydrodesulfurization stage, also in the presence of a hydrogen-containing treat gas and a hydrodesulfurization catalyst. The hydrogen-containing treat gas is cascaded from the next downstream reaction stage, which is an aromatics hydrogenation stage.
