Description: Task Objectives: (1) Support the shakedown of the commercial plant. The plant, which was completed in early 1997, uses the Series C process, which was proven at the pilot-plant scale during Phase I of this project. (2) Improve the Series C process for future plants by completing construction and testing a pilot-scale coal-in-shell processor. This high-throughput, low-cost variation of the process will greatly reduce the cost of future plants using the Series C process. (3) Continue testing the use of foreign coal and high-sulfur US coals to increase the size of the market for the product from the Series C process. (4) Continue work to increase the bulk density of the product by pelletizing. (5) Conduct tests using the Series C Process to upgrade wastes from processing coal and also test upgrading biomass. Quarter Objectives--Continue to support the startup activities of the commercial plant. Support the conduct of bench-scale tests and tests using the Series C pilot plant. Undertake a series of studies to characterize coal. These characterizations could be of use to KFx in developing its commercial processes. The areas studied include a literature review of dust control methods for processed coal; pyrophoricity studies of pyrolized coal; distribution of metals distribution in a swelled coal product; coal briquetting of a KFx product; pretreatment of a feed coal to reduce the sodium content of the ash; and a literature review on techniques to reduce air toxics in the KFx process.
