Effect of nitrogen content of solvent on coal liquefaction
SRC-II recycle solvents contain substantial amounts of heterocyclic compounds such as quinoline: hydrogenated derivatives of such compounds can be good H-donors. Hydrogenation of quinoline is faster than that of the corresponding homocyclic compounds such as naphthalene. Hence, such compounds should aid in maintaining the H-donor capability of recycle solvents at high levels. In a series of coal liquefaction runs to test this premise, there was no effect of tetrahydroquinoline addition to hydrogenated phenanthrene and SRC-II solvent on the product distribution from coal liquefaction, but there was a very pronounced effect with anthracene oil as solvent. Adduction of tetrahydroquinoline led to a net loss of solvent and a very high yield of asphaltenes.
