301 Investigation of the ROPE® process performance on Sunnyside tar sand1990-07ROPE process; Sunnyside tar sand; Western Research Institute; WRI; recycle oil pyrolysis and extraction process; in situ recovery process economics; tar sandWestern Research Institute (WRI) is developing the Recycle Oil Pyrolysis and Extraction (ROPE®) process. Results to date indicate that this process could assist existing surface recovery process economics by producing higher yields of feedstocks from tar sand for the production of unleaded gasoline...
302 Investigative approach to address thermoacoustic vibration in gas-fired heaters and boilers2022Industrial gas-fired boilers, furnaces and heaters occasionally encounter low-frequency vibrations generated by dynamic feedback between the burner (or burners) and acoustic modes in adjacent cavities in the main combustion chamber or ductwork. Feedback occurs when pressure pulses associated with ac...
303 Ion chromatographic analysis of oil shale leachates1990-10-01ion chromatography; oil shale leachates; anionsIon chromatography can be used for the rapid separation and determination of ions in aqueous solutions that would otherwise require a plethora of classical wet chemical techniques. Ion chromatography is finding increasing use in environmental analysis as well as the petroleum and fossil fuel industr...
304 Is tar sand development part of our future?1995-04tar sand development; tar sand; oil productionWhat a difference a decade makes. It has been almost 10 years since the last of several attempts to produce oil from the tar sands at Asphalt Ridge near Vernal, Utah. The only activity since that time has been mining the tar sand for road repair and paving material. The problem is not availability, ...
305 Isothermal pyrolysis and char combustion of oil shales1988-02-03isothermal pyrolysis; char combustion; oil shale; hydrocarbon product formation; flash-pyrolysis oilYields and rates of hydrocarbons evolved during pyrolysis of oil shales have been measured with improved accuracy. Green River and New Albany oil shales were heated in a fluidized sand bed, and volatile pyrolysis products were transferred to a combustion tube and burned. Resulting H20 and C02 were d...
306 Issues of fertility in Utah1988-08The recent decline in births in Utah has generated much interest. Local newspapers have reported the decline and speculated about possible reason, and demographic researchers have struggled to explain the trend. The question is why, after 15 years of increases, did births begin to decline in the ear...
307 Kerogen oil value enhancement research2002-05-22Kerogen; Kerogen oil; oil value enhancement; pure compounds; broad range concentrates; sweet refinery feedstock.Three general categories of products from the Estonia Kukersite kerogen oil were defined: pure compounds, broad range concentrates, and sweet refinery feedstock. Product development and market research center on these three categories. Further attempts were made to identify and test chemical approac...
308 Kinetics of Colorado oil shale pyrolysis in a fluidized-bed reactor1985-05kinetics of Colorado oil shale pyrolysis; fluidized-bed reactor; oil shale pyrolysis; oil shale; hydrocarbon evolutionThe hydrocarbon evolution data of Richardson et al.

310 Laboratory and modeling investigation of a Colorado oil-shale block heated to 900°C1979-12modeling investigation; Colorado oil-shale block; oil shale; retorting; in-situ retortA cylinder of oil-shale, 17.2 by 17.0 cm diameter, was heated in a retort from 23 to 900°C at a rate of 18°C h-1. Total mass loss, oil yield and evolution of individual products are monitored. A one-dimensional model is developed to simulate the heating of the cylinder of oil-shale and the chemist...
311 Lands with wilderness characteristics, Resource Management Plan constraints, and land exchanges: Cross-jurisdictional management and impacts on unconventional fuel development in Utah's Uinta Basin2012-03Utah oil shale; oil sands; unconventional fuel resources; land exchanges; land rightsUtah is rich in oil shale and oil sands resources. Chief among the challenges facing prospective unconventional fuel developers is the ability to access these resources. Access is heavily dependent upon land ownership and applicable management requirements. Understanding constraints on resource acce...
