Abstract
Sequential thermal dissolution (STD) of Geting bituminous coal (GBC) in benzene, methanol, ethanol, and isopropanol was conducted at 150 to 300°C for 2 h. Anthracene was added into the system as the hydrogen acceptor to trace hydrogen transfer (HT) behavior during the STD. All of the soluble portions (SPs) were analyzed with a gas chromatograph/mass spectrometer. The once-through yields of SPs did not fluctuate obviously with raising the thermal dissolution (TD) temperature from 150 to 250°C, but significantly increased over 250°C. HT from GBC to anthracene in benzene, methanol, and ethanol occurred at 300°C and in isopropanol at 250°C. Unlike TD in benzene, alkanolysis significantly proceeded during TD in alkanols at 300°C.
