- This DOE contract continued support for the DOE Coal Sample Bank and Data Base at Penn State. At the beginning of the contract, a new type of container was evaluated for long-term storage of coal samples ranging in quantity from a few grams to over 10 kg (22 lbs). Gieseler fluid behavior, oxidation of pyrite to sulfates, loss of heating value, and other properties were monitored over time. Based on preliminary results, these foil and polyethylene laminate bags were believed to be a significant improvement over the drums, buckets and cans previously used. Use of the bags was therefore instituted with DECS-1, the first sample collected under the contract. Twenty-two DECS samples were collected, ranging in rank from lignite to anthracite and representing the five most productive coal provinces of the US. Over 6500 containers of DECS samples were created under the contract and 750 containers of 34 PSOC samples are supported by the contract. Each sample was characterized by proximate and ultimate analysis, petrographic (vitrinite reflectance and maceral) analysis, physical and thermoplastic testing, and inorganic element analysis. The resulting data, and geologic data on each sample, were entered in a data base which can be used to produce a formatted five-page or one-page printout for each sample. An interactively operated data base can be searched, sorted or summarized to produce tables of selected data or to identify samples meeting a requestor`s criteria. During the period covered, 2,313 printouts, and 204 special data reports resulting in distribution of data on 34,086 samples, were provided on request.
