Fischer–Tropsch Synthesis: Effect Of Ammonia On Product Selectivities For A Pt Promoted Co/Alumina Catalyst, Venkat Ramana Rao Pendyala, Wilson D. Shafer, Gary Jacobs, Michela Martinelli, Dennis E. Sparks, Burtron H. Davis

Center for Applied Energy Research Faculty and Staff Publications

The effects of co-fed ammonia in synthesis gas on the activity and product selectivities of a typical cobalt catalyst (0.5% Pt–25% Co/Al₂O₃) were investigated during the Fischer–Tropsch synthesis using a continuously stirred tank reactor (CSTR). The product selectivities were compared at a similar CO conversion level for various concentrations (10–1000 ppmv) of ammonia, as well as clean (un-poisoned) conditions. The addition of 10–1000 ppmv ammonia (concentration of ammonia with respect to the syngas feed) significantly decreased activity; the percentage of deactivation was similar (∼40%) for the various concentrations of ammonia used. At similar CO conversions, the …

The Irreversible Momentum Of Clean Energy, Barack Obama

United States Department of Energy: Publications

The release of carbon dioxide (CO₂) and other greenhouse gases (GHGs) due to human activity is increasing global average surface air temperatures, disrupting weather patterns, and acidifying the ocean. Left unchecked, the continued growth of GHG emissions could cause global average temperatures to increase by another 4°C or more by 2100 and by 1.5 to 2 times as much in many midcontinent and far northern locations. Although our understanding of the impacts of climate change is increasingly and disturbingly clear, there is still debate about the proper course for U.S. policy—a debate that is very much on display …

Computational Modeling Of A Williams Cross Flow Turbine, Sajjan Pokhrel

Browse all Theses and Dissertations

Hydropower is not only the most used renewable energy source in the United States, but in the world. While it is well known that large hydropower facilities, like the Hoover Dam, provide large amounts of electrical power, there is also a tremendous opportunity for hydroelectric power generation from small scale facilities that has largely been overlooked. The work being presented here studies a new cross flow turbine called the Williams Cross Flow Turbine (WCFT), which was designed to extract electric energy from low head, run-of-the-river, small hydropower sites. To spur the implementation of the WCFT in small hydropower applications, and …

Evaluation Of Earth-Abundant Monometallic And Bimetallic Complexes For Catalytic Water Splitting, Kenneth Kwame Kpogo

Wayne State University Dissertations

The development of affordable water splitting catalysts from Earth-abundant transition metal ions such as Co and Mn is of immense scientific interest. Aiming to develop an efficient water splitting catalyst, a Co(II) complex featuring an asymmetric, pentadentate quinolyl-bispyridine ligand with a phenylenediamine backbone was synthesized and characterized by spectroscopic, spectrometric, and X-ray analysis. The Co ion was selected because of its ability to undergo redox conversions from 3d5 CoIV through 3d8 CoI thereby making it a suitable catalyst that can withstand harsh structural and electronic changes during catalysis. The electrocatalytic water reduction activity of the catalyst at neutral pH gave …

Evaluation Of Flocculation, Sedimentation, And Filtration For Dewatering Of Scenedesmus Algae, Nicholas A. Rhea, Jack Groppo, Czarena Crofcheck

Biosystems and Agricultural Engineering Faculty Publications

Algae can be used as a feedstock for agricultural fertilizers, livestock and poultry feeds, anaerobic digestion, and biofuel production. For each end product, the requirements for moisture content (or solids content) vary, such that a desirable water removal strategy needs to be adaptable to varying levels of water removal. Flocculation, sedimentation, and filtration were evaluated as possible strategies for thickening and dewatering of algae. The goal of this study was to validate that algae cells treated by such means could be processed by vacuum belt filters and to determine the conditions under which the solids content could be increased to …

People understand and have seen that renewable energy has many advantages over conventional energy sources. Because of these advantages, more and more emphasis has been given to generating electrical energy with renewable sources. Among the many renewable and conventional ways currently available for a society to generate electrical power, wind turbines are one of the cheapest ways of doing this. The main objective of this thesis work is to develop a computer program that assesses the wind resource at a given location, designs a wind turbine rotor for optimum power capture for one wind speed, and analyzes the performance of …

The Decline And Recovery Of Thermal Oxidative Stability Of Ultra-Low Sulfur Diesel Blends, Abigail Schoor Cohen

Electronic Theses and Dissertations

Dissertation supervised by Professor Bruce D. Beaver

The oxidative stability of ultra-low sulfur diesel (ULSD) has generally been expected to continuously decline over time. However, recent studies have suggested that it may fluctuate.^1-2 In this study, the oxidative stability of stored commercially purchased ULSD was monitored with a methanol extraction method.³ In this methodology, proposed by Hardy and Wechter, fuel blends are extracted with methanol before and after thermal stressing.⁴ The methanol-soluble layer contains the oxygenated and oxidizable components of the fuel (SMORS) and the change in this mass upon stressing thus represents the oxidative stability of …

Leadership Strategies For Maintaining Profitability In A Volatile Crude Oil Market, Lucky Anderson Braimoh

Walden Dissertations and Doctoral Studies

Volatile crude oil prices significantly affect the profitability of crude oil firms. The purpose of this single case study was to explore strategies some crude oil and gas business leaders used to remain profitable during periods of crude oil price volatility. The target population comprised 8 crude oil and gas business leaders located in Calgary, Canada, whose company remained profitable despite crude oil price volatility. The transformational leadership theory formed the conceptual framework for the study. Data were collected through the use of semistructured face-to-face interviews, company reports, and field notes. Data analysis involved a modified Van Kamm method, which …

Study Of Surface Complexation And Mineral Dissolution During Water-Rock Interaction In High Salinity Waterflooding At Elevated Temperatures, Sameer Salasakar

Masters Theses

"High salinity waterflooding for carbonate reservoirs is efficient and cheap method used for improved oil recovery. Various mechanisms have been proposed including adsorption/desorption on rock surface, mineral dissolution and precipitation, multicomponent ion exchange, interfacial tension reduction, fine migration and double layer expansion. These all process alter the wettability which leads to improved oil recovery.

Objective of this study was to understand processes that occur during water-rock interaction when high salinity water is flooded into the reservoir. In this work, effect of temperature on water-rock interaction is studied along with effect of pH and specific surface areas of calcite at normal …

Land Trust Response To Renewable Energy Siting Challenges In New York, Collin David Adkins

Bard Center for Environmental Policy

Energy policies promoting energy independence, grid modernization, climate change mitigation, and clean energy standards are a leading driver of land-use change in the United States. This has resulted in an increased pressure to develop land. The recent focus by states to expand renewable energy poses an interesting challenge to organizations dedicated to conserving open space and natural resources, creating a potential tension between competing “green” goals. In response, The Land Trust Alliance, a national organization supporting over 1,100 member land trusts, has recently set a goal to “empower land trusts to encourage the buildout of renewable energy facilities while steering …

Stratigraphic, Geochemical, And Geochronological Analysis Of The Wolfcamp-D Interval, Midland Basin, Texas, Zachary S. Perlman

Theses and Dissertations--Earth and Environmental Sciences

Subsurface data derived from ~388 ft of drill core from Martin County (TX) were used to understand the depositional setting of the Wolfcamp-D, a petroleum producing interval in the Midland Basin. Elemental geochemistry collected via x-ray fluorescence revealed a highly variable depositional history marked by the deposition of diverse siliciclastic and carbonate lithofacies. Integration of multiple datasets resulted in the interpretation of nine lithofacies, whose deposition appears cyclical. Correlations between molybdenum and total organic carbon indicate slow recharge of bottom waters and anoxic/euxinicconditions within the basin. The presence of phosphatic nodules coinciding with siliceous black mudrocks suggested high levels of …

Energy Rebound As A Potential Threat To A Low-Carbon Future: Findings From A New Exergy-Based National-Level Rebound Approach, Paul E. Brockway, Harry Saunders, Matthew K. Heun, Timothy J. Foxon

University Faculty Publications and Creative Works

150 years ago, Stanley Jevons introduced the concept of energy rebound: that anticipated energy efficiency savings may be "taken back" by behavioural responses. This is an important issue today because, if energy rebound is significant, this would hamper the effectiveness of energy efficiency policies aimed at reducing energy use and associated carbon emissions. However, empirical studies which estimate national energy rebound are rare and, perhaps as a result, rebound is largely ignored in energy-economy models and associated policy. A significant difficulty lies in the components of energy rebound assessed in empirical studies: most examine direct and indirect rebound in the …

The Water-Electricity Nexus In California: Drought-Induced Risk To Thermal Electricity Generation, Timothy S. Hyles

Cal Poly Humboldt theses and projects

Investigating the possibility that drought might limit the water supply needed for thermal electricity generation in California, power plant water consumption data was compared to urban and agricultural consumptive demands to identify areas where power plants might contribute to regional water stress. To identify areas where power plants might be impacted by water stress, regional power plant, urban, and agricultural water demands were also compared to the available water supply. A list of power plants that would contribute most to regional water scarcity (individually and in aggregate) was highlighted, based on the plant’s water consumption volume, water-intensity, and water source. …
