Selective catalytic hydrogenation of polynuclear heteroaromatic nitrogen compounds with polymer-supported transition-metal compounds. [Quinoline, 5,6- and 7,8-benzoquinoline, acridine and phenanthridine]
The selective catalytic hydrogenation of model coal compounds such as quinoline, 5,6- and 7,8-benzoquinoline, acridine and phenanthridine were studied using transition metal catalysts supported on 2% or 20% cross-linked phosphinated divinylbenzene-polystyrene beads. In all cases, only the nitrogen heterocyclic ring in the above-mentioned polynuclear heteroaromatic nitrogen compounds was reduced, while it was found that the 2% cross-linked beads were three times more active per metal atom than their 20% cross-linked analogues and forty times more active than its homogeneous counterpart using quinoline as the model coal compound and polymer-supported Wilkinson's catalyst. A discussion of these results are presented along with data to show; clearly, the potential of these polymer-supported catalysts in the selective reduction of polynuclear heteroaromatic nitrogen compounds in the presence of known coal liquid constituents such as pyrene, tetralin, methylnaphthalenes, cresols and 2-methylpyridine.
