Procedure
When in Example I, Step Two, the hydrogen donor is indane, decaline, di-, tetra-, and octa-hydroanthracene, C12 and C13 acenaphthenes, tetrahydroacenaphthene, partially hydrogenated anthracene, partially hydrogenated phenanthrene, partially hydrogenated pyrene and mixtures thereof instead of tetralin, the same or similar results are obtained in that the sulfur content of the coal is reduced.
