- The objective of this research project is the development of a unified picture of chemical and mineralogical changes occurring during ashing and slagging of low-rank coals and associated changes in certain slag physical properties during gasification. This project consists of two parts. The first is a study of the effects of ashing conditions on the mineralogical and bulk chemical composition of ashes or slags derived from low-rank coals. The second is a study of two thermophysical properties of coal ash slags under reducing conditions as they relate to composition and temperatures. The slag properties of special interest addressed in this project are viscosity and surface tension. The ashing study involves a suite of approximately fifteen coals ashed at 150/sup 0/C, 750/sup 0/C, and 1000/sup 0/C. The mineralogy and bulk chemical composition of the ash are determined by x-ray diffraction and x-ray fluorescence. 5 refs., 4 tabs.
