✦ Synopsis
Petroleum heavy oil was used as the hydrogen donor and anthracene oil as the co-solvent in the liquefaction of some Colombian coals. It was found that the addition of anthracene oil enhanced the hydrogen donor ability of the petroleum heavy oil, as measured by the THF soluble products. The maximum conversion yields were obtained for an anthracene oil/petroleum heavy oil ratio of between 4/6 and 6/4. The THF-soluble products showed a maximum content of oils when the conversion was higher. This trend was also observed when the coals were pre-swollen, indicating that the diffusion mechanism is very important in this type of reaction.
