Techno-Economic Implications Of Fed-Batch Enzymatic Hydrolysis, Ellen Emanuel

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

As ethanol production continues to increase in the United States, cellulosic ethanol continues to gain traction as a viable option for meeting ethanol demands. In this work, a literature review of techno-economic analyses for cellulosic ethanol was conducted. It was found that pretreatment methods greatly affect the ethanol production costs. There is a lack of techno-economic data comparing a batch enzymatic hydrolysis to a fed-batch enzymatic hydrolysis for a separate hydrolysis and fermentation production process. Consequently, a techno-economic analysis comparing cellulosic ethanol production using batch versus fed-batch enzymatic hydrolysis was conducted. SuperPro Designer software (Intelligen, Scotch Plains, New Jersey), a …

Development Of Cardiac Atrial Kick Shear Wave Elastography To Assess Myocardial Stiffness, Aaron J. Engel

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Increased myocardial stiffness, which is characteristic of many cardiovascular diseases, leads to a loss of diastolic function and is a cause of diastolic heart failure. Current methods to estimate myocardial stiffness rely on pressure-volume relationships derived from invasive cardiac catheter measurements. Noninvasive methods to estimate myocardial stiffness include ultrasound-based and magnetic resonance-based shear wave elastography, where the stiffness of the tissue is related to the propagation speed of a shear wave. Currently, ultrasound-based cardiac shear wave elastography includes acoustic radiation force based methods; however, the in vivo generation and detection of the shear waves in myocardium is significantly degraded due …

Rice Hull Bioreactor For Recirculating Aquaculture, Marlon A. Greensword

LSU Doctoral Dissertations

The engineering of floating media biofilters has been optimized over the years. The backwashing process has made them more energy and water efficient. Likewise, moving bed bioreactors (MBBR) are gaining interest and popularity because they are relatively affordable to build. Yet, developing countries’ aquaculture production remains largely excluded from the advances made in recirculating aquaculture systems (RAS). This discrepancy is partially driven by the high costs of media such plastic beads and Kaldnes (KMT) media, commonly used in MBBR.

This dissertation evaluates the usability and profitability of rice hulls (RH), an abundant by-product in many developing nations, as a sinking …

Biofuels From Crop Residue: Soil Organic Carbon And Climate Impacts In The Us And India, Adam Liska

Adam Liska Papers

The transformation of crop residue to soil organic carbon and CO₂ is a conserved process that occurs globally. Due to the mathematics of carbon intensity calculations found in government regulations, the amount of CO₂ emitted from crop residue per unit of energy in biofuel is largely independent of the amount of residue removed and the location of its removal, as shown by results from the US and India.

Soil organic carbon (SOC) levels are at equilibria determined by carbon inputs from plant material (+I_c) and loss from oxidation to CO₂

Are the US results relevant …

Catalytic Oxidation And Depolymerization Of Lignin In Aqueous Ionic Liquid, Lalitendu Das, Siquan Xu, Jian Shi

Biosystems and Agricultural Engineering Faculty Publications

Lignin is an integral part of the plant cell wall, which provides rigidity to plants, also contributes to the recalcitrance of the lignocellulosic biomass to biochemical and biological deconstruction. Lignin is a promising renewable feedstock for aromatic chemicals; however, an efficient and economic lignin depolymerization method needs to be developed to enable the conversion. In this study, we investigated the depolymerization of alkaline lignin in aqueous 1-ethyl-3-methylimidazolium acetate [C₂C₁Im][OAc] under oxidizing conditions. Seven different transition metal catalysts were screened in presence of H₂O₂ as oxidizing agent in a batch reactor. CoCl₂ and …

Rain gardens are a type of green infrastructure designed to mitigate the adverse effects of stormwater runoff by promoting evapotranspiration, reducing peak flows, and retaining pollutants. Rain gardens can provide additional ecosystem services, defined as benefits that ecosystems provide to people. This includes, but is not limited to, increasing biodiversity by providing habitat, creating green spaces for recreation, and storing carbon. To date, little research has been done integrating these multiple services. My research measured water quality, …

Characterization Of High Oleic Acid Biodiesel: Improving Biofuel Properties, James M. Muskat, Nathan Mosier

The Summer Undergraduate Research Fellowship (SURF) Symposium

In 2016, the world produced an amount of biofuel equivalent to 82,306,000 tonnes of oil. A portion of the biofuels produced was categorized as biodiesel. While still growing as a fuel alternative, current biodiesel fuels are at risk for causing increased engine coking, lower engine performance and durability, oil ring sticking, carbon deposits, and gelling of lubricating oil. Due to these primary issues, biodiesel cannot completely replace petroleum diesel as a fuel source. Instead, biodiesel is commonly blended with petroleum diesel at 5% and 20% (B5 and B20) in the U.S. to create a mixture that has acceptable fuel properties. …
