| dc.description.abstract | Medium-temperature gasifier pitch (MTP) is only partly soluble in acetonitrile, methanol and ethanol. Single-stage pitch extraction with a large quantity of methanol yielded two liquid phases containing 76 wt. % and 27 wt. % pitch respectively. The pitch fractions recovered from these two phases featured similar aromaticity indices. However, the pitch from the pitch-rich phase had a higher average molar mass and gave an improved carbon yield at 1000 °C. Analysis of the methanol-insoluble pitch fraction showed that methanol extraction at reflux temperatures effectively removed boronic acid model compounds from pitch samples spiked with the same. | en_US |
