Abstract: This invention relates to a process involving hydrocracking of a feedstream in which a converted fraction can exhibit relatively high distillate product yields and maintained or improved distillate fuel properties, while an unconverted fraction can exhibit improved properties particularly useful in the lubricant area. In this hydrocracking process, it can be advantageous for the yield of converted/unconverted product for gasoline fuel application to be reduced or minimized, relative to converted distillate fuel and unconverted lubricant. Catalysts and conditions can be chosen to assist in attaining, or to optimize, desirable product yields and/or properties.

Abstract: A method for conducting an interactive financial simulation. The method is implemented at least in part by a computer and includes transmitting an initial financial projection for a fictitious company, transmitting a news story, generating a new share price for the fictitious company based on an index, generating a new financial projection for the fictitious company based on a set of decisions selected for implementation by a participant of the interactive financial simulation, and generating a final share price for the fictitious company based on a final set of decisions selected for implementation by the participant.

Abstract: A hydrocracking process for converting a petroleum feedstock to higher gravity, lower sulfur products, especially ultra low sulfur road diesel fuel. The process may be operated as a single-stage or two-stage hydrocracking. In each case, a hydrocracking step is followed directly by a post-treat hydrodesulfurization zone using a bulk multimetallic catalyst comprised of at least one Group VIII non-noble metal and at least two Group VIB metals with a ratio of Group VIB metal to Group VIII non-noble metal is from about 10:1 to about 1:10. In the two-stage option with interstage ammonia removal, the initial hydrocracking step may be followed by hydrodesulfurization using the bulk multimetallic catalyst prior to the ammonia removal which is followed by the second hydrocracking step. A final hydrodesulfurization over the bulk multimetallic catalyst may follow. The hydrodesulfurization over the bulk multimetallic catalyst is carried out at a pressure of at least 25 barg and preferably at least 40 barg.

Abstract: A method and reactor system for catalytic hydrotreating and hydrocracking liquid hydrocarbon feedstock for producing a cracked liquid feedstock having a reduced contaminant level involves introducing the feedstock into the first reaction zone of a reactor system having a plurality of successive reaction zones, each reaction zone having a hydroprocessing catalyst bed therein, at least the first reaction zone comprising a hydrotreating reaction zone and at least one downstream reaction zone comprising a hydrocracking reaction zone, introducing hydrogen gas into the reactor system for flow through and over the catalyst beds in contact with the liquid in the reaction zones, the hydrogen exothermically reacting with the liquid in the reaction zones for producing an effluent for each reaction zone having a temperature greater than the temperature of the influent feedstock to that reaction zone, introducing liquid feedstock having the same composition as the liquid feedstock introduced into the first reaction zone i

Abstract: The present invention provides a hydrogenation process for producing diamondoid compounds from a petroleum feedstream containing multiple ring naphthenes comprising the steps of:(a) converting multiple ring naphthenes to alkyl substituted adamantanes in the presence of a zeolite catalyst having a Constraint Index of less than 1 in a first stage to form an intermediate product stream; and(b) selectively cracking non-diamondoid components of said intermediate product stream in the presence of a zeolite having a CI less than or equal to 2 to evolve a final product stream enriched in alkyl substituted adamantanes.
