Establishment and maintenance of a coal sample bank and data base

Description: Headspace oxygen contents of several designated drums containing {minus}l inch and {minus}{1/4} inch coal were measured. These measurements were later discontinued by agreement with the Project Manager, as the leakage of plastic drums and buckets has been well documented. During the current reporting period a total of 65 data printouts were distributed. In addition, 10 special data requests were fulfilled by either search/sort and printout or creation of a data disk, resulting in distribution o… more

Measured energy savings and economics of retrofitting existing single-family homes: An update of the BECA-B database

Description: The energy bill for US single-family households was over $77 billion in 1987 (excluding auto fuel purchases), accounting for approximately 20% of national energy expenditures. Large sums are spent on residential retrofits by individual homeowners, government agencies, and utilities. As of late 1987, over 21 million households indicated that they had added at least one energy-saving measure in the previous two years, while a recent Electric Power Research Institute (EPRI) study estimated that ne… more

Novel nanodispersed coal liquefaction catalysts: Molecular design via microemulsion-based synthesis

Description: The objective of this project is to pursue the development of highly dispersed and inexpensive catalysts for improved coal solubilization and upgrading of coal liquids. A novel study of the synthesis of liquefaction catalysts of nanometer size will be carried out. It is based on the molecular design of reverse micelles (microemulsions). These surfactant-stabilized, metal-bearing microdrops offer unique opportunities for synthesizing very small particles by providing a cage-like effects that lim… more

Liquid Phase Methanol LaPorte Process Development Unit: Modification, Operation, and Support Studies

Description: The LPMEOH process was conceived and patented by Chem Systems Inc. in 1975. Initial research and studies on the process focused on two distinct modes of operation. The first was a liquid fluidized mode with relatively large catalyst pellets suspended in a fluidizing liquid, and the second was an entrained (slurry) mode with fine catalyst particles slurried in an inert liquid. The development of both operating modes progressed in parallel from bench scale reactors, through an intermediate scale … more

Temperature Effects on Waste Glass Performance

Description: The temperature dependence of glass durability, particularly that of nuclear waste glasses, is assessed by reviewing past studies. The reaction mechanism for glass dissolution in water is complex and involves multiple simultaneous reaction proceeded, including molecular water diffusion, ion exchange, surface reaction, and precipitation. These processes can change in relative importance or dominance with time or changes in temperature. The temperature dependence of each reaction process has been… more

OTTER Experiments Pertinent to CADE-10

Description: This Argonne report serves as a companion to our CADE-10 paper. To fulfill promises made in that paper, included here are detailed proofs in clause notation, input files compatible with OTTER, and explanations for the choice of approach. Also included are certain of the original and unpublished proofs (of Winker) that answered four open questions, two in equivalent calculus and two in the R-calculus. The organization parallels that of the CADE-10 paper.

Heavy metal removal and recovery using microorganisms

Description: Microorganisms -- bacteria, fungi, and microalgae -- can accumulate relatively large amounts of toxic heavy metals and radionuclides from the environment. These organisms often exhibit specificity for particular metals. The metal content of microbial biomass can be a substantial fraction of total dry weight with concentration factors (metal in dry biomass to metal in solution) exceeding one million in some cases. Both living and inert (dead) microbial biomass can be used to reduce heavy metal c… more

CO sub 2 emissions from developing countries: Better understanding the role of energy in the long term

Description: This study examines energy use and carbon emissions in the developing world. Based on analyses of present energy-use patterns in 17 developing nations, this study presents high emissions and low emissions scenarios for these nations in the year 2025. These nations combined account for two thirds of the energy-related carbon emissions presently generated in the developing world. The analysis reveals that energy demand expands dramatically by 2025 and grows increasingly carbon intensive. In the h… more
