Melismata: Musical Phansies Fitting the Court, Citie and Countrey Humours. Edition and Commentary

Description: Thomas Ravenscroft, the English composer, editor, and arranger, is known for his participation in the St. Paul's Boys' Choir, as instructor of music at Christ's Hospital School, and as a prodigy. His best-known publications are a setting of the psalter, The Whole Booke of Psalmes, and the treatise, A Brief Discourse,which is an effort to revive mensural notation. Ravenscroft's works contain many examples of popular Elizabethan music which he edited and arranged. Part II of this thesis consists of an edition of his third publication, Melismata, a collection of nine rounds and fourteen partsongs. A list of critical notes is also included. The commentary to the edition includes a biography, a discussion of his works, the background and origin of the songs in Melismata, and an analysis of these songs.

Johnson Noise Thermometry for Advanced Small Modular Reactors

Description: Temperature is a key process variable at any nuclear power plant (NPP). The harsh reactor environment causes all sensor properties to drift over time. At the higher temperatures of advanced NPPs the drift occurs more rapidly. The allowable reactor operating temperature must be reduced by the amount of the potential measurement error to assure adequate margin to material damage. Johnson noise is a fundamental expression of temperature and as such is immune to drift in a sensor s physical condition. In and near core, only Johnson noise thermometry (JNT) and radiation pyrometry offer the possibility for long-term, high-accuracy temperature measurement due to their fundamental natures. Small, Modular Reactors (SMRs) place a higher value on long-term stability in their temperature measurements in that they produce less power per reactor core and thus cannot afford as much instrument recalibration labor as their larger brethren. The purpose of this project is to develop and demonstrate a drift free Johnson noise-based thermometer suitable for deployment near core in advanced SMR plants.

Biomass to Gasoline and DIesel Using Integrated Hydropyrolysis and Hydroconversion

Description: Cellulosic and woody biomass can be directly converted to hydrocarbon gasoline and diesel blending components through the use of integrated hydropyrolysis plus hydroconversion (IH2). The IH2 gasoline and diesel blending components are fully compatible with petroleum based gasoline and diesel, contain less than 1% oxygen and have less than 1 total acid number (TAN). The IH2 gasoline is high quality and very close to a drop in fuel. The DOE funding enabled rapid development of the IH2 technology from initial proof-of-principle experiments through continuous testing in a 50 kg/day pilot plant. As part of this project, engineering work on IH2 has also been completed to design a 1 ton/day demonstration unit and a commercial-scale 2000 ton/day IH2 unit. These studies show when using IH2 technology, biomass can be converted directly to transportation quality fuel blending components for the same capital cost required for pyrolysis alone, and a fraction of the cost of pyrolysis plus upgrading of pyrolysis oil. Technoeconomic work for IH2 and lifecycle analysis (LCA) work has also been completed as part of this DOE study and shows IH2 technology can convert biomass to gasoline and diesel blending components for less than $2.00/gallon with greater than 90% reduction in greenhouse gas emissions. As a result of the work completed in this DOE project, a joint development agreement was reached with CRI Catalyst Company to license the IH2 technology. Further larger-scale, continuous testing of IH2 will be required to fully demonstrate the technology, and funding for this is recommended. The IH2 biomass conversion technology would reduce U.S. dependence on foreign oil, reduce the price of transportation fuels, and significantly lower greenhouse gas (GHG) emissions. It is a breakthrough for the widespread conversion of biomass to transportation fuels.

Long Term Processing Using Integrated Hydropyrolysis plus Hydroconversion (IH2) for the Production of Gasoline and Diesel from Biomass

Description: Cellulosic and woody biomass can be directly converted to hydrocarbon gasoline and diesel blending components through the use of a new, economical, technology named integrated hydropyrolysis plus hydroconversion (IH2). The IH2 gasoline and diesel blending components are fully compatible with petroleum based gasoline and diesel, contain less than 1% oxygen and have less than 1 total acid number (TAN). The IH2 gasoline is high quality and very close to a drop in fuel. The life cycle analysis (LCA) shows that the use of the IH2 process to convert wood to gasoline and diesel results in a greater than 90% reduction in greenhouse gas emission compared to that found with fossil derived fuels. The technoeconomic analysis showed the conversion of wood using the IH2 process can produce gasoline and diesel at less than $2.00/gallon. In this project, the previously reported semi-continuous small scale IH2 test results were confirmed in a continuous 50 kg/day pilot plant. The continuous IH2 pilot plant used in this project was operated round the clock for over 750 hours and showed good pilot plant operability while consistently producing 26-28 wt % yields of high quality gasoline and diesel product. The IH2 catalyst showed good stability, although more work on catalyst stability is recommended. Additional work is needed to commercialize the IH2 technology including running large particle size biomass, modeling the hydropyrolysis step, studying the effects of process variables and building and operating a 1-50 ton/day demonstration scale plant. The IH2 is a true game changing technology by utilizing U.S. domestic renewable biomass resources to create transportation fuels, sufficient in quantity and quality to substantially reduce our reliance on foreign crude oil. Thus, the IH2 technology offers a path to genuine energy independence for the U. S., along with the creation of a significant number of new U.S. ...
