Short contact time dissolution of Liddell coal

The thermal dissolution of Liddell coal in tetralin at 400 °C proceeds rapidly. The addition of hydrogen to coal under moderate, uncatalysed conditions is significant and initially proceeds without the elimination of nitrogen, oxygen or sulphur. At extended reaction times, however, oxygen is elimina...

Description
Summary:The thermal dissolution of Liddell coal in tetralin at 400 °C proceeds rapidly. The addition of hydrogen to coal under moderate, uncatalysed conditions is significant and initially proceeds without the elimination of nitrogen, oxygen or sulphur. At extended reaction times, however, oxygen is eliminated via hydrogenolysis reactions. The simulation of product distributions from the thermal dissolution of Liddell coal at 400 °C, and short contact times, has been undertaken using a system of second-order pseudo-kinetic equations. Excellent agreement between the experimental data and the calculated conversions has been obtained.
