  • Patent number: 4221654
    Abstract: Compatibility of solvent refined coal and other coal liquids with conventional petroleum fuels is improved by moderate catalytic hydrogenation of the solvent refined coal liquid to a hydrogen to carbon atomic ratio less than that of corresponding petroleum fractions. As degree of hydrogenation of solvent refined coal is increased, compatibility with petroleum fractions of like boiling range increases to a maximum measured by precipitation of sediment from the blend of equal parts of the two fuels. That maximum is achieved at a hydrogen/carbon ratio below that of the corresponding petroleum fractions. As that ratio is increased toward the ratio characteristic of a like petroleum fraction, compatibility is impaired.

  • Patent number: 4178226
    Abstract: Enhanced compatibility of coal liquids with petroleum based fuels is achieved by removing or modifying the 950.degree. F. plus asphaltene-containing fraction of the coal liquid. The separation or modification can be achieved by distillation, deasphalting, hydroprocessing, and the like.
