20090139903 | Desulfurization of petroleum streams utilizing a multi-ring aromatic alkali metal complex - The present invention relates to a process for removing sulfur from sulfur-containing hydrocarbon streams utilizing a multi-ring aromatic hydrocarbon complex containing an alkali metal ion. Preferably, the sulfur-containing hydrocarbon stream is comprised of high molecular weight hydrocarbons, such as a low API gravity, high viscosity crude, tar sands bitumen, an oil derived from shale, or heavy refinery intermediate stocks such as atmospheric resids or vacuum resids which are typically difficult to desulfurize and contain relatively high amounts of sulfur. However, intermediate refinery streams and refinery product streams may also be treated by the process of the current invention to achieve very low sulfur concentrations to meet environmental specification for fuels sulfur content. | 06-04-2009 |

20100083574 | Modification of rheological properties of coal for slurry feed gasification - The feeding of coal slurries into a gasifier for the production of synthesis gas is improved by modifying the rheological properties of the coal particles so that conventional liquid transfer equipment can be used in the feed transfer process to the gasifier. The coal particle surface modification is accomplished by adsorbing asphaltenes derived from petroleum onto the surfaces of coal particles prior to and/or during contact with the slurry liquid. The coal particles with their surfaces thus modified exhibit lower particle-particle interaction in the liquid slurries to form a shear independent Newtonian fluid or a weakly shear thickening pseudoplastic fluid. The rheological properties of the slurries permit them to be transported reliably into a pressurized, entrained feed gasifier vessel using convention slurry pumps with a low potential expenditure of energy. | 04-08-2010 |

This slurry is then heated if necessary to achieve a viscosity which can be processed conveniently in the gasifier.

20100314235 | HIGH TEMPERATURE HYDROPYROLYSIS OF CARBONACEOUS MATERIALS - Heat from a concentrated solar power source is applied to the conversion of carbonaceous materials such as heavy petroleum crude oils, coals and biomass to liquid hydrocarbons.

The heat from the solar source may be used to generate electricity to operate high temperature steam electrolysis used in generation of the hydrogen. By the use of solar thermal energy sources, hydrocarbon resource utilization for process heat is eliminated along with carbon dioxide evolution associated with burning of the hydrocarbon resource to generate process heat.

The entire cycle may be characterized as including an endothermic step, generally a reduction, and an exothermic step, generally an oxidation, with heat from the exothermic step being transferred from the exothermic step to the endothermic step by means of the circulating contact material. The application of the nuclear or solar heat may be applied to whichever step of the process requires heat from external sources.
