摘要： 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 desufurization 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.

摘要： 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.

摘要： Catalysts for experimentation are produced having a controlled matrix pore structure. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50° C. to 200° C. for a period of time of about 0.1 to 1.0 hour. The dried catalyst particles can be removed from the substrate by several techniques, including scraping, burning, and deforming the substrate material, The resulting catalytic particles can be produced in an amount of about ca. 3 g to 300 g from slurries with volumes between 5 cc to 500 cc, which are suitable for small scale FCC reactors and for high throughput experimentation.

摘要： A process for recovering oil from tar sands by subjecting the tar sands to aqueous extraction to produce a bitumen-rich layer containing bitumen, water and solids and a bitumen-lean layer containing relatively less bitumen and relatively more water and solids. The solids present in the bitumen-lean layer contain a substantial portion of finely divided clay having adhered organic matter. The clay solids are retained with the bitumen from the bitumen-lean layer and the bitumen-clay mixture is pyrolyzed. Pyrolysis of the bitumen-lean layer containing clay having adhered organic matter reduces the volume of aqueous tailings which would otherwise be produced and also results in increased hydrocarbon yields.

摘要： A method for passivating metal contaminants present in a hydrocarbon feedstock which become deposited on cracking catalyst is described. The method is directed at passing the cracking catalyst through a passivation zone having a reducing atmosphere maintained at an elevated temperature by the introduction of a process reducing gas. The unsaturated hydrocarbon content of the reducing gas is decreased prior to the introduction of the process reducing gas into the passivation zone to thereby lower the rate of coke formation. In a preferred embodiment process reducing gas is passed through a hydrogenation zone adapted to hydrogenate an unsaturated hydrocarbon present in the process reducing gas prior to the process reducing gas being added to the passivation zone.
