- SRI International is conducting studies of the effects of liquid water at temperatures and pressures near its critical point on the behavior of coal. The present study involves the construction and operation of a cell for visual observation of the process. The cell is batch charged with a dispersion of coal particles in solvent; it is designed for continuous flow operation should that mode of operation become desirable. It can be electrically heated to 550°C and can handle pressures to 5000 psi. Direct observation of individual particles takes place through a pair of diamond windows, a lens assembly, and a television monitoring system. A number of runs have been performed during this quarter, including runs with Wyodak and Illinois No. 6 coal with both water and tetralin. A video tape of two runs was submitted with a monthly report during this quarter, and a tape with four runs in included with this report. Unfortunately just as our experience with the cell was developing, one of the diamonds cracked and the replacement is not expected before December. Accordingly we have spent some time operating the cell with a single window and front lighting.
