ABSTRACT:

Progress reports are presented for the following two tasks: (1) thermal behavior of slurry reactors used for indirect coal liquefaction; and (2) coal liquefaction under supercritical conditions. For task 1, work is being done using three indirect liquefaction routes involving synthesis gas - the Fischer-Tropsch reaction, the one-step conversion to methanol, and the two-step conversion to methanol. Experimental work during the last quarter was concentrated on examining the first step of the two-step process - the carbonylation of alcohols using potassium alcoholates as the catalyst. The alcohol used was methanol; the catalyst used was potassium methoxide. The reaction was very selective to methyl formate. The only observable by-products were a small amount of white precipitate and formaldehyde. The objective of task 2 is to measure transfer rates for naphthalene extraction by carbon dioxide in order to determine how mass transfer coefficients vary with pressure, flow rate and bed height. During this past quarter, the new apparatus worked effectively and mass transfer coefficients were obtained at 20 atm and 25C. 8 figs., 3 tabs. (ERA citation 11:047166)
