| Popis: | The effects of microwave receptors to coal (receptor/coal) ratio and the period of heating by microwave energy on the solubilization of Turkish coals (Tuncbilek, Mugla-Yatagan, Beypazari lignites, and Zonguldak bituminous coal) in tetralin have been investigated. V{sub 2}O{sub 5} and TiO{sub 2} were used as microwave receptors. The changes of liquid product yield indicated that it depended significantly on the type and amount of receptor and the type of coal. A significant increase in the lignite conversions to oil fractions was observed by the addition of the V{sub 2}O{sub 5} receptor. The use of TiO{sub 2} receptor decreased the yield of THF soluble coal products. However, both V{sub 2}O{sub 5} and TiO{sub 2} receptors decreased the yield of preasphaltene (PAS) and asphaltene (AS) due to their catalytic effect on the coal liquefaction. 15 refs., 9 figs., 1 tab. |
