Evaluating Hydrocarbon Source Rock For Unconventional Shale Oil Play From Seismic And Well Log Data; Kingak Shale, North Slope, Alaska, Sarah Elisabeth Leedberg 2012 University of Texas at El Paso

Evaluating Hydrocarbon Source Rock For Unconventional Shale Oil Play From Seismic And Well Log Data; Kingak Shale, North Slope, Alaska, Sarah Elisabeth Leedberg

Open Access Theses & Dissertations

It has been proposed that Acoustic impedance (AI) responses can be used to estimate total organic carbon (TOC) within thick, clay rich shale. The purpose of this work is to evaluate the effectiveness of the AI inversion technique, and establish a methodology that can be applied to other basins. The Kingak Formation (lower Jurassic to early Cretaceous), located on the North Slope of Alaska, has been extensively evaluated for its unconventional potential. The Kingak is shale and is known to have greater than 30 percent clay. Because clay has ductile properties it makes it difficult to stimulate a well through …


Distributed Solar Photovoltaic Grid Integration System : A Case Study For Performance, Ming Shen 2012 Portland State University

Distributed Solar Photovoltaic Grid Integration System : A Case Study For Performance, Ming Shen

Dissertations and Theses

The needs to the sustainable development of electricity, energy efficiency improvement, and environment pollution reduction have favored the development of distributed generation (DG). But the problems come with increasing DG penetration in distribution networks. This thesis presents the Solar Energy Grid Integration System (SEGIS) Stage III project done by Portland General Electric (PGE), Advanced Energy, Sandia National Lab on a PGE selected distribution feeder. The feeder has six monitored commercial solar PV systems connected. The total power output from the PV systems has the potential to reach 30% of the feeder load. The author analyzes the performance of the solar …


High Pressure Synchrotron X-Ray Diffraction Studies Of Superprotonic Transitions In Phosphate Based Solid Acids, Juan Daniel Hermosillo 2012 University of Texas at El Paso

High Pressure Synchrotron X-Ray Diffraction Studies Of Superprotonic Transitions In Phosphate Based Solid Acids, Juan Daniel Hermosillo

Open Access Theses & Dissertations

Certain phosphate based solid acids, such as CsH2PO4 and RbH2PO4, have been shown to exhibit an abrupt, several-order-of-magnitude increase in their proton conductivity when heated above a temperature threshold. This so called superprotonic behavior allows the above-mentioned materials to function as fuel cell electrolytes at temperatures between 150C and 300C, a remarkable application that attracted significant interest especially from the automobile industry. Yet, the microscopic structures and dynamic mechanisms responsible for this behavior are not fully understood. In fact, until very recently, the very nature of the superprotonic behavior has been debate, with some groups attributing the steep proton enhancement …


Technical Feasibility Of Storage On Large Dish Stirling Systems, Charles E. Andraka, K Scott Rawlinson, Nathan P. Siegel 2012 Bucknell University

Technical Feasibility Of Storage On Large Dish Stirling Systems, Charles E. Andraka, K Scott Rawlinson, Nathan P. Siegel

Faculty Journal Articles

Dish-Stirling systems have been demonstrated to provide high-efficiency solar-only electrical generation, holding the world record at 31.25%. This high efficiency results in a system with a high possibility of meeting the DOE SunShot goal of $0.06/kWh. Current dish-Stirling systems do not incorporate thermal storage. For the next generation of non-intermittent and cost-competitive solar power plants, we propose a thermal energy storage system that combines latent (phase-change) energy transport and latent energy storage in order to match the isothermal input requirements of Stirling engines while also maximizing the exergetic efficiency of the entire system. This report takes an initial look at …


Timing Of Residential Electric Loads To Reduce Air Emissions From Power Generation, Michelle Marinich Rogers 2012 Wayne State University

Timing Of Residential Electric Loads To Reduce Air Emissions From Power Generation, Michelle Marinich Rogers

Wayne State University Theses

Over the course of a day, power utilities must respond to changing demand by dispatching or shedding output from different generators. Each generator is associated with a unique profile of air emissions, based on the type of fuel consumed, installed pollution controls, and the generator's efficiency. The aim of this study is to determine whether shifting electric demand to times when cleaner generation sources are available would result in overall emissions reduction.

Dynamic wholesale pricing in the electric power market, specifically the Locational Marginal Price (LMP), provides a means to estimate the marginal generator fuel type. This knowledge was used …


Catalytic Effects Of Period Iv Transition Metal In The Oxidation Of Biodiesel, Bradley Clark 2012 Wayne State University

Catalytic Effects Of Period Iv Transition Metal In The Oxidation Of Biodiesel, Bradley Clark

Wayne State University Theses

CATALYTIC EFFECTS OF PERIOD IV TRANSITION METALS IN THE OXIDATION OF BIODIESEL

BRADLEY R CLARK

December 2011

Advisors: Dr. Steve Salley, Dr. Simon Ng, Dr. Naiem Henien

Major: Alternative Energy Technology

Degree: Masters of Science

Transition metals have the ability to catalyze free radical autoxidation of unsaturated fatty acid methyl esters (i.e., biodiesel). The catalytic effects of the eight period IV transition metals: V, Cr, Mn, Fe, Co Ni, Cu and Zn in soybean oil and cottonseed oil-based biodiesel are investigated. All metals produced a reduction of the induction period of biodiesel, although there are considerable differences in their catalytic …


(In, Al) Co-Doped Zinc Oxide As A Novel Material System For Quantum-Well Multilayer Thermoelectrics, Sean C. Teehan 2012 University at Albany, State University of New York

(In, Al) Co-Doped Zinc Oxide As A Novel Material System For Quantum-Well Multilayer Thermoelectrics, Sean C. Teehan

Legacy Theses & Dissertations (2009 - 2024)

Waste heat recovery from low efficiency industrial processes requires high performance thermoelectric materials to meet challenging requirements. The efficiency such a device is quantified by the dimensionless figure of merit ZT=S2σT/қ, where S is the Seebeck coefficient, σ is the electrical conductivity, T is the absolute temperature and қ is the thermal conductivity. For practical applications these devices are only cost-effective if the ZT is higher than 2.


From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt 2012 Colby College

From Pond To Pump: Microalgae As A Feedstock For Biodiesel, Anna H. Leavitt

Honors Theses

The global reliance on fossil fuels is an unsustainable practice that has led to the depletion of finite resources and the accumulation of greenhouse gases in the atmosphere, leading to global climate change (Demirbas 2010). Transportation accounts for about a third of carbon dioxide (CO2) emissions in the United States. Demand for oil continues to increase and resources are becoming more uncertain. Increased production of renewable fuels such as biofuels can help ease the dependence on fossil fuels. Although interest and production in biofuels has been increasing in the past decade, current feedstocks do not meet efficiency needs and some …


Synthesis And Photoluminescence (Pl) Of Gold (I) And Silver (I) Metal Complexes With 1-Methylbenzimidazole Diphenylphosphine (Mbdp): Potential Sensing Applications For Volatile Organic Compounds, Darkus Elizabeth Jenkins 2012 North Carolina Agricultural and Technical State University

Synthesis And Photoluminescence (Pl) Of Gold (I) And Silver (I) Metal Complexes With 1-Methylbenzimidazole Diphenylphosphine (Mbdp): Potential Sensing Applications For Volatile Organic Compounds, Darkus Elizabeth Jenkins

Dissertations

Volatile organic compound(s), VOC(s), detection have become a highly demanding area of research due to potential harmful effects to the ecosystem. The search for methods of VOC sensor devices has led to the examination of photoluminescence and photoluminescent materials such as metal complexes. Their luminescent properties markedly with phosphine and/or nitrogen based ligands, bridging ligands, have the ability to accommodate metal atoms with short metal – metal distances. It is of great interest to accomplish short metal interactions as the photoluminescent properties can be altered. We show the synthesis and structural characterization of the bridging ligand, 1-methylbenzimidazole diphenylphosphine. We examined …
