1526 Heightened oil sands extraction by pressure cycles2009oil sands extraction; pressure cycles; hot water extraction of bitumenHot water extraction of bitumen from oil sands has been commercially applied for decades. The extraction process is greatly aided by the addition of caustics and other reagents, which can adversely impact handling and disposal at process end. Recent attention has been on increasing process efficienc...

1533 High-temperature interactions between multiple-metals and kaolinite2002high-temperature interactions; multiple-metals; kaoliniteHigh-temperature combustion flue gases provided the environments for this investigation of multiple-metals interactions with dispersed kaolinite. Whereas previous research was restricted to interactions of single-metals with kaolinite powders, this work focuses on understanding how kaolinite transfo...
1534 High-temperature reactors for underground liquid-fuels production with direct carbon sequestration2008-03-20high-temperature reactors; underground liquid-fuels production; direct carbon sequestration; oil; heavy oil; tar sands; oil shale; coal; liquid fuelsThe world faces two major challenges: (1) reducing dependence on oil from unstable parts of the world and (2) minimizing greenhouse gas emissions. Oil provides 39% of the energy needs of the United States, and oil refineries consume over 7% of the total energy. The world is running out of light crud...

1538 Homogenizer/subsampler for tar sand process streams
1539 Hot water processing of U.S. tar sands -- Water recycle and tailings disposal1984hot water processing; U.S. tar sands; water recycle; tailings disposal; bitumen recoveryTailings disposal and water recycle are vital factors for the industrial development of a hot water process for the recovery of bitumen from U.S. tar sands. Based on batch laboratory experiments, with 4 to 12 kg tar sand charge, tailings sedimentation behaviours are presented and discussed for tar s...

1546 Hydrotreating process kinetics for bitumen and bitumen-derived liquids1993-05hydrotreating process kinetics; bitumen; bitumen-derived liquids; Whiterocks bitumenHydrodenitrogenation, hydrodesulfurization and resid conversion data for the Whiterocks bitumen and bitumen-derived liquid were analyzed using a modified power rate law model. The model incorporated the space velocity and pressure since the plug flow equation may not be applicable to laboratory-scal...
1547 Hydrotreating the bitumen from the Whiterocks oil sand deposit1992-11-20hydrotreating bitumen; Whiterocks oil sand deposit; bitumenThe bitumen from the Whiterocks oil sand deposit in the Uinta Basin of eastern Utah was hydrotreated in a fixed-bed reactor to determine the extent of upgrading as a function of process operating variables. The process variables investigated included reactor pressure (11.2-16.7 MPa); reactor tempera...
1548 Hydrotreating the Whiterocks oil sand bitumen and bitumen-derived liquid (Abstract only)1992-12hydrotreating; Whiterocks oil; oil sand; bitumen; bitumen-derived liquid; bitumen conversion; heteroatom reduction; heteroatomConversion of Utah's Uinta Basin bitumens to liquid fuels requires molecular weight reduction of the parent material as well as removal of heteroatoms.
