B. Chawla et al., MECHANISM STUDIES OF COAL-LIQUEFACTION IN A NONDONOR SOLVENT USING C-14-LABELED 1-METHYLNAPHTHALENE, Energy & fuels, 8(2), 1994, pp. 355-359
Neither methyl nor ring C-14-labeled methylnaphthalene shows extensive
incorporation into the soluble products produced during coal liquefac
tion. The two coals utilized in this study showed as high or even a hi
gher conversion at short reaction times in the nondonor 1-methylnaphth
alene as in the donor solvent tetralin. The data eliminate significant
solvent incorporation as a reason for the high coal conversion in the
nondonor solvent.
