Supercritical fluids for reaction and extraction of coal and heavy oils. First quarterly progress report, September 1, 1981-November 30, 1981
A program for the study of supercritical extraction of coal and coal liquids is being carried out. The purpose of this study is aimed at developing a fundamental understanding of supercritical extraction with emphasis on extraction of coal liquids with supercritical water and deashing of coal liquids, SRC-bottoms and possibly shale oils. The study will focus on the use of supercritical extraction techniques for extraction and fractionation of heavy residues which are often mixed with mineral matter and other non-volatile matter. The study will also include the supercritical extraction of model compounds and their mixtures. An experimental apparatus and procedure have been designed and ordered. A schematic diagram of the experimental set-up is shown. A special custom-made Autoclave reactor has been designed. The reactor is a 1 liter Magnedrive II agitated autoclave rated at 500 psi and 450/sup 0/C and provided with ports for inlet and outlet for the process components, temperature and pressure measurement and cooling water connections. The reactor will be provided with a multiple zone electric furnace for heating the reactor to operating conditions. The top of the reactor (flange), and sampling tubes will be provided with heating elements so as to maintain a constant temperature throughout the reactor and sampling line assembly.
