The experimental unit for the coal-water experiments has been erected. Some modifications in the inlet and outlet ports of the autoclave have been made. The tranfer lines have been kept to a minimum to avoid any temperature gradients and refluxing of water in the lines. The system has been leak tested and is found to be in proper operating condition. Samples of brown coal have been received and the coal has been crushed and ground under adequate precautionary measures to a desirable particle size. It has been planned to initially carry out the experiments with a coal sample in the -100 mesh range. Major changes in the experimental set-up to study the solubility of solids in supercritical fluids have been made. Two equilibrium cells will be used instead of an autoclave. A metered supply of the supercritical fluid phase will be provided to the two cells and the extracted sample will be collected in a suitable solvent for chromatographic analysis.
