✦ Synopsis
Petroleum heavy oil and anthracene oil were used as hydrogen donor solvents in a coal liquefaction test. A positive synergistic effect was obtained when mixed (petroleum heavy oil; anthracene oil) solvent was employed. The temperature of maximum conversion was also lower for this mixed solvent than for any of the solvents alone. It is shown from the 'H n.m.r. spectral data that petroleum heavy oil acts as a hydrogen donor to anthrdcene oil resulting in hydroaromatic derivatives. These hydroaromatic species donate hydrogen to the coal fragments. The 'H n.m.r. spectral data allow monitoring of the temperature at which the petroleum heavy oils have maximum donor capacity and consequently the temperature for coal liquefaction in this process.
