Naphthalene (II), quinoline (III), isoquinoline (IV), 6-methylquinoline (V) and 2-methylquinoline (VI) can be hydrogenated selectively to form 1,2,3,4-tetrahydronaphthalene (VII) (100% yield at 22/degree/C), 1,2,3,4-tetrahydroquinoline (VIII) (73% yield at 22/degree/C), 1,2,3,4-tetrahydroisoquinoline (IX) (70% yield at 90/degree/C), 6-methyl-1,2,3,4-tetrahydroquinoline (X) (100% at 90/degree/C), and 2-methyl-1,2,3,4-tetrahydroquinoline (XI) (76% at 90/degree/C) by use of the Ziegler-type catalyst Co(stearate)/sub 2/-AlEt/sub 3/ (I) in a hexane solvent at a hydrogen pressure of 700 psi. Catalyst (I) does not hydrogenate dibenzothiophene, nitroquinolines or 4-chloro-2-methylquinoline. By extrapolating these results, a maximum yield of hydrogenation product from low sulfur coal using catalyst (I) was achieved by either maintaining the temperatures as low as 100/degree/C for a long period of time or by conducting the process at high temperature (/approximately/150/degree/C) for a short period of time. Hydrogenation of low sulfur coal resulted in a hydrogenated liquid product equal to 20% of the initial coal weight at 100/degree/C and 800 psi hydrogen pressure. Microanalysis of the product showed the hydrogen content had doubled. On the other hand, attempts to hydrogenate high sulfur content coal (Illinois No. 6), gave unsatisfactory results. 27 refs., 3 tabs.
