Combustion of municipal solid wastes with oil shale in a circulating fluidized bed | 1996-06-30 | The authors of this report have invented an integrated process for the treatment of municipal solid waste (MSW). In this process, after recycling steps to save usable materials such as aluminum, other metals, and glass have been completed, the resulting refusederived fuel (RDF) is co-combusted with ... | |

The coming boom in Utah's school age and college age populations: state and county scenarios | 2002-09 | Population analysts have for some time anticipated a significant increase in the school age population (5 through 17 years of age) of Utah beginning around 2004 and extending for at least a decade. At this point the question is not whether the boom will materialize, but rather, the exact timing, mag... | |

Common conditions for heavy oils | 1987 | Heavy oils; Colloidal admixtures; Hydrocarbons; Asphaltenes; Trace metals; Organic residues; Alberta basin; Eastern Venezuela basin; Athabasca; Orinoco; Heavy-oil depositys; Common conditions for heavy oils | Field evidence suggests that conditions for the collection and retention of various hydrocarbons exert control over the composition of resident hydrocarbon mixtures. Heavy-oil deposits demonstrate that control very clearly. Heavy oils are essentially colloidal admixtures of hydrocarbons, usually acc... |

Comparative study of organic rich solids present in Utah and Athabasca oil sands | 1989 | organic rich solids; Utah oil sands; Athabasca oil sands; comparative study of oil sands | The presence of humic matter modifies the hydrophilic character of some oil sand solids surfaces and thereby results in serious problems in bitumen recovery using water-based processes. In the present work the fraction enriched with humic matter was separated from the bulk of Utah oil sand solids, u... |

Comparing 10 methods for solution verification and linking to model validation | 2005-03-25 | Grid convergence; V&V process; Solution Verification; Discretized continuum; Lawrence Livermore National Laboratory; Computational analyses; Discretization; Continuum process; Finite elemental analyses | Grid convergence is often assumed as a given during computational analyses involving discretization of an assumed continuum process. In practical use of finite difference and finite element analyses, perfect grid convergence is rarely achieved or assured, and this fact must be addressed to make stat... |

Comparison of kinetic analysis of source rocks and kerogen concentrates | 1994-05-10 | Shales and kerogen concentrates from the Green River, Rundel, Ohio, Kimmeridge, and Phosphoria formations were examined by Pyromat II micropyrolysis and kinetic parameters were determined by the shift-in-Tm a x , discrete distribution, modified Friedman, and modified Coats-Redfern methods. Overall, ... | |

Comparison of methods for measuring kerogen pyrolysis rates and fitting kinetic parameters | 1987-03-23 | We determine rates of product evolution during pyrolysis of several petroleum source rocks and isolated kerogens by nonisothermal techniques, including Rock Eval pyrolysis and pyrolysis-MS/MS. The resulting data are analyzed by nonlinear regression and simpler correlation techniques in terms of disc... | |

Composition and origin of the Uinta Basin bitumens | 1963-01 | The names of the three formations of interest, from oldest to youngest, the Wasatch, Green River, and Uinta, have been used largely as facies terms to differentiate sediments which were believed to be of different age but actually were deposited simultaneously. The Wasatch is predominantly fluviatil... | |

Compositional and kinetic analysis of oil shale pyrolysis using TGA-MS | 2012-04 | compositional analysis; kinetic analysis; oil shale pyrolysis; TGA-MS; oil shale; western United States; oil production | There are vast resources of oil shale in the western United States. Development of technically and economically effective technologies for the conversion of oil shale to liquid fuels will help provide a long-term and secure source of transportation fuels. Developing good understanding of the decompo... |

Concentration of eastern oil shales by froth flotation | 1983 | Concentration of Eastern oil shale has been accomplished by size reduction and froth flotation techniques. The efficiency of kerogen recovery depends on the extent of size reduction (1iberation) as well as frother and promoter additions. Certain grinding aids sucli as sodium silicate and fuel oil ha... | |

Conjunctive surface and groundwater management in Utah: Implications for oil shale and oil sands development | 2011-12-31 | Unconventional fuel development; Conjunctive water use; Surface water; Groundwater; Utah; Utah water law; Oil shale; Oil sands | Unconventional fuel development will require scarce water resources. In an environment characterized by scarcity, and where most water resources are fully allocated, prospective development will require minimizing water use and seeking to use water resources in the most efficient manner. Conjunctive... |

Constraints on the commercialization of oil shale | 1978 | oil shale; commercialization of oil shale; constraints of commercialization; economic problems; institutional problems; surface oil shale technologies | Beyond supporting reseearch, development, and demonstration projects, government energy policy is directed toward introducing new energy technologies into commercial use. Considerable policy attention has been focused on the commercialization of energy process plants that produce substitutes for imp... |

Control of geological carbon sequestration in the western United States | 2011-05 | coal; carbon dioxide; electric utilities; carbon sequestration; sequestration; geological sequestration; climate change | In the near future, the use of coal may be legally restricted due to concerns over the effects of its combustion on atmospheric carbon dioxide concentrations. Carbon capture and geologic sequestration offer one method to reduce carbon emissions from coal and other hydrocarbon fuel. While the federal... |

Control of process aid used in hot water process for extraction of bitumen from tar sand | 1984-07-31 | Tar sand; Bitumen; Tar sand feed; Free surfactant content; Slurry; Bitumen froth recovery; Bitumen; Hot water process; Bitumen extraction; Extraction circuit | The hot water process is sensitive to the nature of the tar sand feed, which varies. An alkaline process aid, usually NaOH, is normally added to the conditioning step of the process and is needed to obtain good bitumen recovery from most tar sand feeds. The invention is based on the discovery that, ... |

Conversion of hydrocarbon gases to liquid in the fluidized bed retort | 1987-06-12 | A free radical steady-state mechanism has been developed to explain qualitative and quantitative aspects of the generation of hydrocarbon gases in the solid-recycle fluidized bed retort. The mechanism relies on what is known about butane cracking. The 1- and 2-butyl free radicals have been studied a... | |
