MAINTENANCE OF THE COAL SAMPLE BANK AND DATABASE

PDF Version Also Available for Download.

Description

This project generates and provides coal samples and accompanying analytical data for research by DOE contractors and others. The five-year contract has been completed and a six-month no-cost extension is under way; this will continue the limited distribution of samples and data to DOE, its contractors and grantees. All activities specified under the five-year contract have been completed. Eleven DECS samples were collected, processed to a variety of particle sizes, heat-sealed in foil laminate bags under argon, and placed in refrigerated storage. All were analyzed for basic chemical composition, inorganic major and trace element composition including hazardous air pollutant elements, ... continued below

Description

This project generates and provides coal samples and accompanying analytical data for research by DOE contractors and others. The five-year contract has been completed and a six-month no-cost extension is under way; this will continue the limited distribution of samples and data to DOE, its contractors and grantees. All activities specified under the five-year contract have been completed. Eleven DECS samples were collected, processed to a variety of particle sizes, heat-sealed in foil laminate bags under argon, and placed in refrigerated storage. All were analyzed for basic chemical composition, inorganic major and trace element composition including hazardous air pollutant elements, petrographic composition and characteristics, thermoplastic behavior (if applicable), and other properties relevant to commercial utilization. Most were also analyzed by NMR, py/gc/ms, and a standardized liquefaction test; trends and relationships observed were evaluated and summarized. Twenty-two DECS samples collected under the previous contract received further processing, and most of these were subjected to organic geochemical and standardized liquefaction tests as well. Selected DECS samples were monitored annually to evaluate the effectiveness of foil laminate bags for long-term sample storage. Twenty-three PSOC samples collected under previous contracts and purged with argon before storage were also maintained and distributed, for a total of 56 samples covered by the contract. During the five years, 524 samples in 1501 containers, 2075 data printouts, and individual data items from 30327 samples were distributed. In the subject quarter, 23 samples, 16 data printouts, and individual data items from 2507 samples were distributed. All DECS samples are now available for immediate distribution at minus 6 mm (-1/4 inch), minus 0.85 mm (- 20 mesh U.S.), and minus 0.25 mm (- 60 mesh U.S.).
