Use of ultrasound for enhanced direct coal liquefaction: Quarterly report, August 1988--December 1988
The objective of this project is to investigate whether high-intensity ultrasound is capable of inducing coal liquefaction under mild conditions of temperature and pressure in the presence of a solvent and in the presence or absence of a liquefaction catalyst. The role of high-intensity ultrasound in effective dispersion of solids and/or activation of catalysts will also be investigated using an appropriate liquefaction catalyst. The study will be conducted in two parts. First model compounds (bibenzyl and benzyl phenyl ether) will be subjected to high-intensity ultrasound to determine if any chemical bonds are broken under the action of ultrasound. In the second part, the effect of ultrasound on both catalyzed and non-catalyzed coal liquefaction will be determined. Two coals (sub-bituminous and bituminous) will be studied using tetralin as a hydrogen donating solvent and molybdenum sulfide as catalyst. 3 refs., 3 figs.
