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 catalyst will also be investigated using an appropriate liquefaction catalyst. The study is being conducted in two parts. In the first part, model compounds are being subjected to high-intensity ultrasound to determine if any chemical bonds are broken under the action of ultrasound. In the second part of the study, the effect of ultrasound on both catalyzed and noncatalyzed coal liquefaction will be determined. Two coals (sub-bituminous and bituminous) will be studied using an appropriate hydrogen donor solvent and molybdenum sulfide as catalyst. 4 refs., 2 tabs.
