- This report describes progress on research during the third quarter of this contract dealing with applications of coal pretreatment techniques in coal hydroliquefaction by co-processing. The objectives of the project are to investigate various coal pretreatment techniques, such as mild alkylation, and to determine the effect of these pretreatment procedures on the reactivity of the coal. Reactivity enhancement will be evaluated under both direct hydroliquefaction and co-processing conditions. Research during the past quarter focused on the continuation of development for analytical techniques that will be required to rapidly assess the chemical changes in coal brought about by the pretreatment procedures. The tool we have been developing for this purpose is photoacoustic FTIR. Coal liquefaction and liquefaction coprocessing experiments in the microautoclave tubing bomb and 300-cc stirred autoclave reactors were initiated. Also, a procedure by which two-stage close-coupled liquefaction and/or coprocessing can be simulated in the 300-cc stirred autoclave was developed. 1 ref., 7 figs., 2 tabs.
